Easy Encryption

Integrate with Adyen using our Easy Encryption (EE) solution to accept payments while the payment data is encrypted in the shopper's browser or application. This integration provides stricter security protocols.

Implementing EE in a mobile payment flow offering payment cards results in faster load times and an overall improvement of the shopper experience.

Main benefits

Security

EE uses only PCI/NIST approved cryptographic algorithms. The RSA key size is 2048 bits, and it is unique to your user account.

The client generates a unique AES 256-bit key at each transaction. This key is used in CCM mode for both encryption and authentication.

  • The public key (RSA) can be downloaded from the Adyen Customer Area (CA)

    For this, log in the Customer Area using your company-level account, go to Settings / Users, filter the list of users by System in the drop-down box, and then open the Web Service (ws) user page. On this page you can find the public key on the Easy Encryption pane, or (if the key is not available yet), click Generate and then Save (at the page bottom) to create a new key.

  • The secret key (RSA) is known only to Adyen, and it is stored in encrypted form on Adyen's servers.

  • All card data is end-to-end encrypted, and it is never visible to the merchant.

  • Payment authorisation occurs through a server-to-server API call to the Adyen platform where you pass the encrypted card data.

  • The encrypted data is valid for a period of 24 hours, and its validity is tied to your public key.

Easy Encryption code examples

Have a look at code examples showing sample Easy Encryption implementations on GitHub.

Adyen hosted

In this case an Easy Encryption library is hosted by Adyen with your public key injected into JavaScript code. You retrieve this library from the unique URL provided to you by Adyen, and thus you don't need to download and host the adyen.encrypt.min.js on your own servers.

Log in the  Adyen Customer Area (CA) using your company-level account.
  1. Go to Settings → Users and filter the list of users by System in the drop-down box.
  2. Navigate to the Web Service (ws) user page.
  3. Go to Easy Encryption → Library location.
    If the library is not available yet, click Generate and then Save to create a new URL.

Form template

Build your payment form using this template and add a way to reference to this form from JavaScript. For example, define a unique  id attribute value for this form by adding  id="adyen-encrypted-form".
<form method="POST" action="#handler" id="adyen-encrypted-form">
    <input type="text" size="20" autocomplete="off" data-encrypted-name="number" />
    <input type="text" size="20" autocomplete="off" data-encrypted-name="holderName" />
    <input type="text" size="2" maxlength="2" autocomplete="off" data-encrypted-name="expiryMonth" />
    <input type="text" size="4" maxlength="4" autocomplete="off" data-encrypted-name="expiryYear" />
    <input type="text" size="4" maxlength="4" autocomplete="off" data-encrypted-name="cvc" />
    <input type="hidden" value="generate-this-server-side" data-encrypted-name="generationtime" />
    <input type="submit" value="Pay" />
</form>

Also, do the following:

  • For the form.action attribute, replace #handler to the payment handler URL on your server.
  • Card input fields should not have a name attribute, but are annotated by the data-encrypted-name attribute, to mark them for encryption.

    Replacing name with data-encrypted-name restricts raw card data from being posted to your servers and avoids impact transaction security and violate PCI regulations.

  • Add a hidden  generationtime field to include a server-side timestamp in the data you submit with the form. It determines whether a payment request is valid or not: transactions submitted later than 24 hours from the timestamp value are refused. 

    The generation time value must be created server-side, because the client browser system clock may not be correctly synchronised, which would cause the payment transaction to fail.

JavaScript

<script type="text/javascript" src="https://test.adyen.com/hpp/cse/js/{your Test WS user's library token}.shtml"></script>
<!-- For live: 
   <script type="text/javascript" src="https://live.adyen.com/hpp/cse/js/{your Live WS user's library token}.shtml"></script>
   Note that this token is not your public key, but a library token instead.
-->

Initialise the easy encryption form as in the normal HTML Form based integration. Note that the AMD style is not yet available for the hosted EE library.

// The form element to encrypt.
var form    = document.getElementById('adyen-encrypted-form');

// Form and encryption options. See adyen.encrypt.simple.html for details.
var options = {};

// Create the form.
// Note that the method is on the adyen object, not the adyen.encrypt object.
adyen.createEncryptedForm(form, options); 
</script>


If you have implemented a single-page interface and do not want the form to reload the page when the payment gets submitted, implement the onsubmit option.

After including the JavaScript cryptographic library, you can use JavaScript or AJAX to customize the POST submission behaviour.

For example, you can:

  • Pass an additional options parameter in the createEncryptedForm method.
  • Change the name of the encrypted data container. Its default name is adyen-encrypted-data.
  • Submit the form using AJAX instead of the default submit action, as shown in this example:
var encryptedBloblFieldName = "myFieldName";

options.name = encryptedBlobFieldName;
options.onsubmit = function(e) {
    var encryptedData = form.elements[encryptedBlobFieldName].value;
    // ... Your AJAX code here ....
    e.preventDefault();
};

adyen.createEncryptedForm(form, options);

Merchant hosted

This integration binds to existing HTML in the page, adding a hidden input containing the encrypted card data to the form on the moment the form is submitted. The complete integration requires HTML markup to be present in the page, as well as accompanying JavaScript to enable the behaviour.

  1. Download adyen.encrypt.min.js and host it yourself. Both HTML-based and JavaScript-only integrations are supported.
  2. Download adyen.encrypt.nodom.min.js and host it yourself. Only supports JavaScript-only integration.

Form template

Build your payment form using this template and add a way to reference to this form from JavaScript. For example, define a unique  id attribute value for this form by adding  id="adyen-encrypted-form".
<form method="POST" action="#handler" id="adyen-encrypted-form">
    <input type="text" size="20" autocomplete="off" data-encrypted-name="number" />
    <input type="text" size="20" autocomplete="off" data-encrypted-name="holderName" />
    <input type="text" size="2" maxlength="2" autocomplete="off" data-encrypted-name="expiryMonth" />
    <input type="text" size="4" maxlength="4" autocomplete="off" data-encrypted-name="expiryYear" />
    <input type="text" size="4" maxlength="4" autocomplete="off" data-encrypted-name="cvc" />
    <input type="hidden" value="generate-this-server-side" data-encrypted-name="generationtime" />
    <input type="submit" value="Pay" />
</form>

Also, do the following:

  • For the form.action attribute, replace #handler to the payment handler URL on your server.
  • Card input fields should not have a name attribute, but are annotated by the data-encrypted-name attribute, to mark them for encryption.

    Replacing name with data-encrypted-name restricts raw card data from being posted to your servers and avoids impact transaction security and violate PCI regulations.

  • Add a hidden  generationtime field to include a server-side timestamp in the data you submit with the form. It determines whether a payment request is valid or not: transactions submitted later than 24 hours from the timestamp value are refused. 

    The generation time value must be created server-side, because the client browser system clock may not be correctly synchronised, which would cause the payment transaction to fail.

JavaScript

Accompanying the above the HTML template, there are two variants to including the EE library. The original plain JavaScript variant relies on a global adyen.encrypt object, while on popular demand a AMD style module has been added.

Include the Adyen Client-Side Encryption library to your page.

<script type="text/javascript" src="js/adyen.encrypt.min.js"></script>

Enrich a form in your page with the EE on submit and (optionally) validation behaviours.

// The form element to encrypt.
var form    = document.getElementById('adyen-encrypted-form');
 
// The public key.
var key     =   "your key as retrieved from the Customer Area Web Service user page";

// Form and encryption options. See adyen.encrypt.simple.html for details.
var options = {};

// Bind encryption to the form.
adyen.encrypt.createEncryptedForm(form, key, options);

Make sure you include require.js or an alternative AMD module loader in your page.

<script src="path/to/libs/require.js/2.1.17/require.min.js"></script>

You can either rename the adyen.encrypt.min.js into adyen/encrypt.js, or add a paths configuration:

// Your paths config, or rename the adyen.encrypt.min.js to adyen/encrypt.js require.config({ paths: { 'adyen/encrypt' :
'../simple/js/adyen.encrypt.min' } });

In the main.js or a similar file, enrich the form using a require call.

require(['adyen/encrypt'], function(adyenEncrypt) {
    // The form element to encrypt.
    var form    = document.getElementById('adyen-encrypted-form');
 
    // The public key.
    var key     =   "your key as retrieved from the Customer Area Web Service user page";
 
    // Form and encryption options. See adyen.encrypt.simple.html for details
    var options = {};
 
    // Bind encryption to the form.
    adyenEncrypt.createEncryptedForm(form, key, options);
});
</script>

If you have implemented a single-page interface and do not want the form to reload the page when the payment gets submitted, implement the onsubmit option.

After including the JavaScript cryptographic library, you can use JavaScript or AJAX to customize the POST submission behaviour.

For example, you can:

  • Pass an additional options parameter in the createEncryptedForm method.
  • Change the name of the encrypted data container. Its default name is adyen-encrypted-data.
  • Submit the form using AJAX instead of the default submit action, as shown in this example:
var encryptedBloblFieldName = "myFieldName";

options.name = encryptedBlobFieldName;
options.onsubmit = function(e) {
    var encryptedData = form.elements[encryptedBlobFieldName].value;
    // ... Your AJAX code here ....
    e.preventDefault();
};

adyen.createEncryptedForm(form, options);

The public key is associated with the Web Service (ws) user account you use to submit the API payment request. If no key has been generated yet, you can create one from Adyen Customer Area (CA).

For this, log in the Customer Area using your company-level account, go to Settings / Users, filter the list of users by System in the drop-down box, and then open the Web Service (ws) user page. On this page you can find the public key on the Easy Encryption pane, or (if the key is not available yet), click Generate and then Save (at the page bottom) to create a new key.

JavaScript only

In case the HTML integration does not fulfill your setup requirements, the library has been split up into two parts since release V0_1_11. The newly introduced part is an HTML-independent encryption.

As with all EE integrations, make sure that no card data is sent to your server unencrypted.

<script type="text/javascript" src="js/adyen.encrypt.nodom.min.js"></script>
<script type="text/javascript">
(function() {
    var key     =   "your key as retrieved from the Adyen Customer Area Web Service user page"; 
    var options = {}; // See adyen.encrypt.nodom.html for details

    var cseInstance = adyen.encrypt.createEncryption(key, options);

    function encryptMyData() {

        var postData = {};

        var cardData = {
            number : cardNumber,
            cvc : cvc,
            holderName : holderName,
            expiryMonth : expiryMonth,
            expiryYear : expiryYear,
            generationtime : generationtime
        };

        postData['adyen-encrypted-data'] = cseInstance.encrypt(cardData);

        // AJAX call or different handling of the post data.
    }

})();
</script>


The public key is associated with the Web Service (ws) user account you use to submit the API payment request. If no key has been generated yet, you can create one from Adyen Customer Area (CA).

For this, log in the Customer Area using your company-level account, go to Settings / Users, filter the list of users by System in the drop-down box, and then open the Web Service (ws) user page. On this page you can find the public key on the Easy Encryption pane, or (if the key is not available yet), click Generate and then Save (at the page bottom) to create a new key.

Make a card payment

In easy encryption integration, the additionalData object in the payment authorisation request needs to include the encrypted data that stores the credit card information. 

  • The card.encrypted.json object needs to be nested inside the additionalData element.
  • To use the encrypted data in a payment request, assign the adyen.encrypted.data value to the card.encrypted.json key element when you send the request.
  • The Adyen client encryption library encrypts the card data when the shopper submits the payment form, and it sends the encrypted data to the payment form action handler as an adyen.encrypted.data string.
Name Type Required Description
card.encrypted.json String (tick)

Holds encrypted card data and timestamp:

  • Card holder
  • Card number
  • CVC
  • Expiry date
  • Generation time

card.encrypted.json

In this context, so as a child element of additionalData, card.encrypted.json is a name key in a key-value pair.

(tick)

It represents a name key, and as such it takes a corresponding string value.

{
    "additionalData" : {
       "card.encrypted.json" : "adyenjs_0_1_10$aKV"
    }
}
(error)

It does not represent a nested JSON object.

{
    "additionalData" : {
        "card" : {
            "encrypted" : {
                "json" : "adyenjs_0_1_13$WuTY9g"
            }
        }
    }
}

When the shopper clicks Pay, the encrypted data is sent to your server. Make a server-to-server call to request a payment to Adyen.  

The below examples show you how to make a payment request using JSON and SOAP.

curl -u "ws@Company.YourCompany":"YourWsPassword" \
   -H "Content-Type: application/json" \
   -X POST \
   --data \
   '{
       "additionalData": {

       }
     ,
       "amount" : {
           "value" : 20000,
           "currency" : "EUR"
       },

Payment response:

Go to API playground

If the message passes validation, a risk analysis is performed. Depending on the outcome, an authorisation is attempted. You receive a response with the following fields:

Name Type Returned by default Description
pspReference
String (tick)

Adyen's 16-digit unique reference associated with the transaction/the request. This value is globally unique; quote it when communicating with us about this request.

resultCode
String (tick)

The outcome of the payment. The possible values are:

  • Authorised
  • Refused
  • Error
  • Cancelled
  • Received
  • RedirectShopper
authCode String

(tick)

Authorisation code: 

  • When the payment is authorised successfully, this field holds the authorisation code for the payment. 
  • When the payment is not authorised, this field is empty.
refusalReason
String (error)
When the payment is not authorised, it is refused, or if an error occurs, this field holds Adyen's mapped reason for the refusal or a description of the error.
  • The additionalData object can include standard, as well as acquirer raw data.
    You can implement the additionalData object to include extra fields and receive additional information in your response.
  • When a payment authorisation response includes resultCode and refusalReason, the transaction failed or was declined.
    Check their values for further details about any issues that affected the operation.

Payment request fields

Name Type Required Description
merchantAccount String (tick)
The merchant account identifier you want to process the (transaction) request with.
amount String (tick)
A container object for the payable amount information for the transaction.

It contains the following elements:

  • currency
  • value
currency String (tick)
The three-character ISO currency code.
value int (tick)

The payable amount that can be charged for the transaction, in minor units.

The transaction amount needs to be represented in minor units according to the Currency codes table. Some currencies do not have decimal points, such as JPY, and some have 3 decimal points, such as BHD. For example, 10 GBP is submitted as 1000, whereas 10 JPY is submitted as 10.

reference
String (tick)
A reference to uniquely identify the payment. This reference is used in all communication with you about the payment status. We recommend using a unique value per payment; however, it is not a requirement.

If you need to provide multiple references for a transaction, you can enter them in this field. Separate each reference value with a hyphen character ("-").

This field has a length restriction: you can enter max. 80 characters.

shopperIP String (error)

The shopper's IP address.

We recommend you provide this data, as it is used in a number of risk checks. For example: number of payment attempts, location based checks.

shopperEmail String (error)

The shopper's email address.

We recommend you provide this data, as it is used in velocity fraud checks.

shopperReference String (error)

The shopper's reference for the payment transaction.

We recommend you provide this data.

This field is required for recurring payments.

fraudOffset int (error)

An integer value that is added to the normal fraud score. The value can be either positive or negative.

selectedBrand String (error)

Some payment methods require defining a value for this field to specify how to process the transaction.

For the MisterCash payment method, it can be set to:

  • maestro (default), to be processed like a Maestro card, or
  • bcmc, to be processed like a MisterCash card.
deliveryDate Date (error) This specifies the date and time the goods of the order would be delivered, in ISO 8601 format: YYYY-MM-DDTHH:mm:ss.sssZ

 

merchantOrderReference String (error)

This reference allows to link multiple transactions to each other.

shopperInteraction

  • Whether the shopper is a returning customer.

By default, for the web service API Adyen assumes Ecommerce shopper interaction.

This field has the following possible values:

  • Ecommerce - Online transactions where the card holder is present (online). For better authorisation rates, we recommend sending the card security code (CSC) along with the request.
  • ContAuth - Card on file and/or subscription transactions, where the card holder is known to the merchant (returning customer). If the shopper is present (online), you can supply also the CSC to improve authorisation (one-click payment).
  • POS - Point-of-sale transactions where the shopper is physically present to make a payment using a secure payment terminal.
  • Moto - Mail-order and telephone-order transactions where the shopper is in contact with the merchant via email or telephone.

Custom endpoints

Although generic URL endpoints for our APIs are still supported (payment API, recurring API), we recommend setting up merchant-specific endpoints. This is the default endpoint configuration option for new merchants.

Merchant-specific endpoints are available only for API integrations, and only in our live environment.

For test purposes, you can use our generic test points.

Merchant-generic API URL endpoint

The standard, generic payment API URL endpoints to communicate with the Adyen payment API are built as shown in this example:

https://pal-live.adyen.com/pal/servlet/Payment/v25/capture

The example shows the standard, generic URL endpoint to make a payment capture request.

Merchant-specific API URL endpoint

Each company account is provided with a unique hostname to communicate with Adyen's APIs.

By connecting to this merchant-specific hostname, Adyen has more control over the routing of transactions. This allows Adyen to improve service robustness and availability for our merchants.

By default all transactions for a merchant-specific endpoint are routed to the same infrastructure as the standard endpoint, however in case of an infrastructure problem on the standard endpoint, especially if the cause is outside of Adyen's scope of control, alternative routing can be enabled to backup infrastructure and new infrastructure can be provisioned on demand.

Example

Convert the generic API endpoint with path “/pal/servlet/Payment/v25/authorise” from:

https://pal-live.adyen.com/pal/servlet/Payment/v25/authorise

to:

https://f96e63be5147-TestCompany.pal-live.adyenpayments.com/pal/servlet/Payment/v25/authorise

Endpoint format

The custom endpoint has the following format:

https://[random]-[company name].pal-live.adyenpayments.com
random

A random string of hex-encoded bytes to make the hostname unpredictable.

company name

The company name is included in the URL endpoint.

  • If the name is too long:
    it is shortened.
  • If the name includes underscores or hyphens:
    any underscores and/or hyphens are stripped.

Endpoint settings

You can access the API endpoint(s) of your company account through the Adyen Customer Area (CA):

  • Log in to the Adyen Customer Area (CA) using your credentials.
  • In the left navigation sidebar, select Settings.
  • On the Settings page, click API URLs.
  • On the API URLs page, you can see the configured endpoint(s) for your company account.

Click API URLs to access the endpoint overview page.

In this example, the TestCompany account has two API URL endpoints: one is configured to communicate with our European servers, whereas the other is set up to exchange data with our US-based servers.
This setup allows you to optimize data traffic depending on the region you operate in.

Support local payment methods

Create a new skin and configure the local payment methods and configure HMAC to be used when calculating your payment request's signature.

Retrieve a list of the available local payment methods and offer to your active shopper in the country they are carrying out the transaction from.

Some payment methods restrict WebView in the app for security reasons. We recommend using the following if you want to display local payment method in your app: . We recommend using the following if you want to display local payment method in your app:

For Directory lookup call:

For alternative methods, the shopper is redirected to the issuer's page for making the payment.

Make a POST to directory.shtml.

All the fields mentioned in the request example (currencyCode, merchantAccount, paymentAmount, skinCode, merchantReference, sessionValidity and merchantSig), except countryCode, are mandatory.

It is recommended that you provide the countryCode field, to accurately state the actual location of the payment so that the correct payment methods for that location are retrieved.

The directory lookup returns the available payment methods for the shopper based on the country they are shopping from, the amount and currency and skin code you provided. The returned data is a JSON object containing an array of the payment methods. You can parse the response and provide the list of payment methods to your shopper. 

Directory lookup request:

curl --data \
     'countryCode=DE&currencyCode=EUR&merchantAccount=TestMerchant&merchantReference=Test_directory_lookup&paymentAmount=2000&sessionValidity=2015-12-25T10%3A31%3A06Z&skinCode=sH9qpMyS&merchantSig=94AwPXSxs0ECicXi1UDdKEmdzHQ6rf7EF9CC%2FzUO5Tg%3D' \

Payment response

After shoppers complete a payment, they are redirected to a default result page. You can set a custom result page in the skin configuration section.

We append URL parameters to the resultURL value to inform you about the payment status of the payment.

When you direct shoppers to the Adyen platform, you need to cryptographically sign the payment session with a shared secret key. When we return to you the payment status as URL parameters, we use the same shared secret key to sign the data. This ensures that the data has not been tampered with.

Example of a redirect URL to a result page:

http://yourSite.com/pRes.jsp

Example of a corresponding resultURL:

http://yourSite.com/pRes.jsp?merchantReference=Internet%20order%2012345&skinCode=4aD37dJA&shopperLocale=en_GB&authResult=AUTHORISED&pspReference=1211992213193029&merchantSig=CPb2cObMxmIIE0khO8WhEYyKDJs%3D

<!-- Appended URL parameters:
* merchantReference = Internet order 12345
* skinCode = 4aD37dJA
* shopperLocale = en_GB
* authResult = AUTHORISED
* pspReference = 1211992213193029
* merchantSig = CPb2cObMxmIIE0khO8WhEYyKDJs%3D
 -->

Response fields

These are the parameter that are returned with a payment response:

Name Type Returned by default Description
authResult String (tick)

Returns the outcome of the payment.
It can take one of the following values:

  • AUTHORISED: the payment authorisation was successfully completed
  • REFUSED: the payment was refused. Payment authorisation was unsuccessful.
  • CANCELLED: the payment was cancelled by the shopper before completion, or the shopper returned to the merchant's site before completing the transaction.
  • PENDING: it is not possible to obtain the final status of the payment.
    This can happen if the systems providing final status information for the payment are unavailable, or if the shopper needs to take further action to complete the payment.
  • ERROR: an error occurred during the payment processing.
pspReference String (error)

Adyen's 16-digit unique reference associated with the transaction/the request. This value is globally unique; quote it when communicating with us about this request.


When authResult equals PENDINGERROR or CANCELLED, the pspReference may not yet be known; therefore, it may be empty or not included.
merchantReference String (tick) The reference you assigned to the original payment.
skinCode String (tick) The code that identifies the skin used to process the payment.

merchantSig

String (tick)
The signature in Base64 encoded format.

The signature is generated by concatenating the values of a number of the payment session fields, and by computing the HMAC using the shared secret, as configured in the skin.

paymentMethod String (error) The payment method used in the transaction.
When authResult equals CANCELLED, the payment method may not be known; in this case, it is not included.
shopperLocale String (tick)

The  shopperLocale value provided in the payment request.

If no value is specified in the request, the default value en_GB is returned.

merchantReturnData

String (error)

If you define this field in the payment session setup, the value is returned as is.
This information is useful to build a custom result page, and it integrates seamlessly with the shopper's session on your server.
When the payment status is defined, we send you a server-to-server notification. This notification is the recommended way to update the payment status in your backoffice.
The notification system is more reliable in its delivery because the  resultURL parameter relies on the shopper's browser/computer/Internet connection, any of which could fail at any time.

We recommend setting a fixed resultURL in the skin configuration.
However, sometimes it may be preferable to set the result URL on a per-payment basis: to override the resultURL value specified in the skin configuration, you need to set the result URL for the payment session with the  resURL parameter.

additionalData.acquirerReference String (error)

This field is returned for open invoice in the result URL.

Modifications EE

You can submit modifications through your merchant account through the Adyen Customer Area (CA). If you are processing more than a handful of payments on a daily basis, we recommend automating this process; to do this, we make available a web service that accepts the modification requests from your server.

To submit modification messages through our API, you need to provide valid authentication credentials:

  • The user name format is ws@Company.[YourCompanyAccount].
  • To set the corresponding password, go to the the Adyen Customer Area (CA), then select Settings  -> Users.

Adyen replies to modification requests with an appropriate response message, for example captureReceivedcancelReceived or refundReceived. This message acknowledges your modification request; however, it does not serve as a modification confirmation. After your request is processed, you receive a notification to inform you if the payout was successful.

These are the modification request types you can submit. You can also see the endpoints for these requests:

You can capture payments only for payment methods that support distinct authorisations and captures.

After authorising a payment, you can capture it to complete the transaction and collect the payment.

Request

To capture an authorised payment, you send a modification request to the capture action, where you pass the fields described below.

To define a capture delay, go to the Adyen Customer Area (CA), then select Settings | Merchant Setting | Capture Delay.

The Adyen Customer Area (CA) offers an option to configure an automated capture process to automatically capture payments after a specified number of days, ranging from no delay, i.e. immediate capture, up to 14 days.

Name Type Required Description
merchantAccount String (tick)

The merchant account where the transaction, for which the request needs to be initiated, was processed.

modificationAmount Class (tick)

The amount to capture. It consists of:

  • value
  • currency
The  currency must match the currency used in the original payment request.

The value must be smaller than or equal to the authorised amount.

value int (tick)

The payable amount that can be charged for the transaction, in minor units.

The transaction amount needs to be represented in minor units according to the Currency codes table. Some currencies do not have decimal points, such as JPY, and some have 3 decimal points, such as BHD. For example, 10 GBP is submitted as 1000, whereas 10 JPY is submitted as 10.
currency String (tick)

The three-character ISO currency code.

The  currency value must match the corresponding  currency value used in the original payment request.
originalReference String (tick)
The  originalReference value corresponds to the  pspReference value assigned to the original payment.

You receive the pspReference with:

  • The payment status, or
  • The authorisation notification.
reference String (error)
If you want, you can specify your reference for the modification request.
The reference is visible in the Merchant Backoffice and in the reporting section.
This field has a length restriction: you can enter max. 80 characters.

Response

If the message you send with the call is syntactically valid you receive a captureReceived response with the following fields:

Name Type Returned by default Description
pspReference String (tick)

Adyen's 16-digit unique reference associated with the transaction/the request. This value is globally unique; quote it when communicating with us about this request.

response String (tick)
  • If the request is successful, the returned value is [capture-received].
  • If it fails, an error message is returned.

Capture final result

In most cases, the final result of a capture is sent with a notification message whose eventCode value is CAPTURE.

The  pspReference in this notification is the same as the  pspReference in the capture modification response.

The success field in the response indicates if the capture was successful or not:

  • true: the capture was successful
  • false: the capture failed. In this case, the notification message includes a reason field with a short description of the problem.

Offline capture

Some payment methods handle the capture process offline. Sometimes, we may receive a failure. In such a scenario, we send a notification message whose eventCode value is CAPTURE_FAILED.

The pspReference of this notification is the same as the pspReference in the capture modification response.

The success field in the response is set to true.

Request:

merchantAccount=TestMerchant&originalReference=9313547924770610&reference=YourModificationReference&modificationAmount.currency=EUR&modificationAmount.value=500

Response:

pspReference=8312534564722331&response=%5Brefund-received%5D

If you are not sure whether a payment has been correctly captured, and at the same time you want to reverse the payment authorisation, you can issue a cancel or refund.

Request

To initiate a cancellation or refund of an authorised payment that may or may not have been captured, you send a modification request to the cancelOrRefund action, where you pass the fields below.

Name Type Required Description
merchantAccount String (tick) The merchant account where the transaction, for which the request needs to be initiated, was processed.
originalReference String (tick)
The  originalReference value corresponds to the  pspReference value assigned to the original payment.

You receive the pspReference with:

  • The payment status, or
  • The authorisation notification.
reference String (error)
If you want, you can specify your reference for the modification request.
The reference is visible in the Merchant Backoffice and in the reporting section.
This field has a length restriction: you can enter max. 80 characters.

Response

If the message you send with the call is valid and if the specified merchantAccount is correct, you receive a cancelOrRefundReceived response with the following fields:

Name Type Returned by default Description
pspReference String (tick)

Adyen's 16-digit unique reference associated with the transaction/the request. This value is globally unique; quote it when communicating with us about this request.

response String (tick)
  • If the request is successful, the returned value is [cancelOrRefund-received].
  • If it fails, an error message is returned.

Cancel or refund scenarios

The final result of a refund is sent with a notification message whose eventCode value is REFUND.

The pspReference of this notification is the same as the pspReference in the refund modification response.

The success field in the response indicates if the refund was successful or not:

  • true: the refund was successful
  • false: the refund failed. In this case, the notification message includes a reason field with a short description of the problem.

Payment authorised but not captured

If the payment is authorised, but not yet captured, it is cancelled.

 If the selected payment method for the transaction does not support cancellation, the transaction amount us fully refunded.

Cancellation

If the cancel or refund modification request produces a cancellation, the final result is sent with a notification message whose eventCode value is CANCEL_OR_REFUND.

The pspReference of this notification is the same as the pspReference in the cancel or refund modification response.

The success field in the response indicates if the cancellation was successful or not:

  • true: the cancellation was successful
  • false: the cancellation failed. In this case, the notification message includes a reason field with a short description of the problem.

Refund

If the cancel or refund modification request produces a refund, the final result is sent with a notification message whose eventCode value is CANCEL_OR_REFUND.

The pspReference of this notification is the same as the pspReference in the cancel or refund modification response.

The success field in the response indicates if the refund was successful or not:

  • true: the refund was successful
  • false: the refund failed. In this case, the notification message includes a reason field with a short description of the problem.

Failure

If the cancel or refund modification request fails, the final result is sent with a notification message whose eventCode value is SUCCESS=FALSE.

The pspReference of this notification is the same as the pspReference in the cancel or refund modification response.

The success field in the response is set to false: the refund failed.

The notification message includes a reason field with a short description of the problem.

Notifications EE

We send you notifications to inform you about the outcome of an action: for example, when a payment is made, a modification is processed, or a report is available for download, etc. We notify you about the action and whether it was successful or not.

The purpose of notifications is to sync your backoffice system, so that payment and modification statuses are always up to date.

(tick) You receive capture notifications for capture requests submitted via your web service or the Adyen CA.
(error) You do not receive capture notifications for automatic captures initiated by the Adyen platform.

Notification configuration

To configure notifications, go to Adyen Customer Area (CA)  → Settings → Server communication. On this page select one of existing notifications (if there are any) or add a new notification (by default, choose Standard Notification).

Then, on the notification settings page, do the following:

  • Specify the URL to submit notifications to.
  • Set the communication method (SOAP, JSON, HTTP POST).
  • Enter a user name and a password for HTTP basic authentication.

Ports to use:

Port Transport layer Application layer
80 TCP HTTP
Default port for HTTP traffic
443 TCP

HTTPS
Default port for HTTPS traffic

8080 TCP HTTP

Notification server

You need to set up a server to receive and accept the notifications we send you with a JSON/SOAP call or through HTTP POST. Your system needs to be able to handle requests and responses containing additional fields, as well as duplicate notifications for the same transaction.

Depending on the message payload, notification messages can include a number of different fields.
The fields included in a notification message can vary, depending on the event types that trigger it.

Adyen reserves the right to introduce new fields in the future.
Therefore, make sure your listening service does not expect a fixed, predefined set of values.

A notification message can refer to one or more transactions.
These are the fields that can be included in a notification message.

Name Type Returned by default Description
live Boolean (tick)

Informs about the origin of the notification:

  • true: the notification originated from the live environment.
  • false: the notification originated from the test environment.
notificationItems List (tick) A container object for the details included in the notification.
notificationItems list includes one or more NotificationRequestItem objects.

  • eventCode
  • eventDate
  • merchantAccountCode
  • operations
  • merchantReference
  • originalReference
  • paymentMethod
  • reason
  • success
additionalData Object (error)

The additionalData object is a generic container that can hold extra fields.

It contains the following elements:

  • shopperReference
  • shopperEmail
  • authCode
  • cardSummary
  • expiryDate
  • authorisedAmountValue
  • authorisedAmountCurrency

shopperReference

String (tick) The ID that uniquely identifies the shopper. This shopperReference is the same as the shopperReference used in the initial payment.
shopperEmail String (tick) The shopper's email address.
authCode String (error)

Authorisation code: 

  • When the payment is authorised successfully, this field holds the authorisation code for the payment. 
  • When the payment is not authorised, this field is empty.
cardSummary String (error)

Returns the last 4 digits of the credit card.

Only digits allowed. No alphabetic characters.
expiryDate String (error)

Returns the card expiry date.

  • Format: MM/YYYY

authorisedAmountValue

String (error)

Value of the amount authorised.

Scenario 1 - Zero value auth transaction

Some issuers don't allow a zero value transaction. In this case Adyen authorises a minimum amount, for example Euro 1.00, to verify the shoppe's card. After successful authorisation, Adyen's system automatically cancel the authorisation. The actual authorised amount is returned in this field which may differ from the amount sent in in the payment request.

Scenario 2 - Available amount

A shopper makes a transaction of Euro 10 using a gift card but the card contains only Euro 06. In this case Adyen deducts the available amount and keeps the pending amount open to be completed with other payment options. The authorised amount is returned in this field.

You can enable this feature using Adyen Customer Area (CA)Merchant accountSettingsServer CommunicationAdditional Settings.

authorisedAmountCurrency String (error)

Currency of the authorised amount.

amount String (tick)

A container object for the payable amount information for the transaction.

It contains the following elements:

In case of HTTP POST notifications, currency and value are returned as URL parameters.

currency String (tick)
The three-character ISO currency code.
value int (tick)

The payable amount that can be charged for the transaction, in minor units.

The transaction amount needs to be represented in minor units according to the Currency codes table. Some currencies do not have decimal points, such as JPY, and some have 3 decimal points, such as BHD. For example, 10 GBP is submitted as 1000, whereas 10 JPY is submitted as 10.

This field displays the amount sent in the payment request.

pspReference

String

(tick)

Adyen's 16-digit unique reference associated with the transaction/the request. This value is globally unique; quote it when communicating with us about this request.

In REPORT_AVAILABLE response you receive a file name in this field.

In PAIDOUT_REVERSED event code pspsreference is for Capture's pspsreference.

eventCode String (tick)

The type of event the notification item refers to.

When eventCode returns AUTHORISATION , it does not necessarily mean that the payment authorisation request has been successfully processed.

The authorisation is successful if successtrue.

If success = false, check the  the reason value for further information on the authorisation failure cause.

This can occur, for example, if an error occurs or if the transaction is refused.

eventDate Date (tick)

The time when the event was generated.

merchantAccountCode

String

(tick) The merchant account identifier used in the transaction the notification item refers to.
operations List (tick)

This field holds a list with the modification operations supported by the transaction the notification item refers to.

The available operations in the list give information on the follow-up actions concerning the payment.
You may be requested to:

  • Capture the payment (for example, if auto-capture is not set up),
  • Cancel the payment (if the payment has not been capture yet), or
  • Refund the payment (if the payment has already been captured).

This reference is used in all communication with you about the payment status.
We recommend using a unique value per payment; however, it is not a requirement.

If you need to provide multiple references for a transaction, you can enter them in this field.
Separate each reference value with a hyphen character ("-").

This field has a length restriction: you can enter max. 80 characters.

By default, merchantReference is always returned with payment notifications,
as merchantReference returns the reference field value of the corresponding payment request.
In this case, returned by default = (tick)

Modification requests do not require sending a merchant reference value along with the call.
Therefore, the corresponding notifications do not include it by default.
In this case, returned by default = (error)

An empty merchantReference field in a notification message takes null as a value.

originalReference String (error)
If the notification item is about a... ...then:

success Boolean (tick)

Informs about the outcome of the event (eventCode) the notification refers to:

  • true: the event (eventCode) the notification refers to was executed successfully.
  • false: the event was not executed successfully.

When eventCode returns AUTHORISATION , it does not necessarily mean that the payment authorisation request has been successfully processed.

The authorisation is successful if successtrue.

If success = false, check the  the reason value for further information on the authorisation failure cause.

This can occur, for example, if an error occurs or if the transaction is refused.

Event codes

eventCode holds information about the type of event the notification is informing you about. The following table gives an overview of some of the values this field can take.

This notification comes always after the CAPTURE notification with Success = True.

REFUND_FAILED( ** )

Whenever a capture or refund actually failed after it was processed by the third party we return this notification. It basically means that there was a technical issue which needs to be further investigated. Most of the times it is need to be retried to make it work.

PAIDOUT_REVERSED ( * )

When we receive back the funds because it couldn't be paid to the shopper, we book the transaction to PaidOutReversed.

Dispute events
REQUEST_FOR_INFORMATION(**) Whenever a shopper opens an RFI (Request for Information) case with the bank we will send this notification. You should upload defense material which gives the information to the shopper to understand the charge.
CHARGEBACK( ** ) Whenever the funds are really deducted we send out the chargeback notification.

The presence of a transaction in this notification does not have direct financial consequences, nor is action required by the merchant. This is only the case if a chargeback is received (which is eventually sent out separately). Use this notification, for example, to identify fraudulent transactions with a 3D secure liability shift, which are not a (and may not be) chargeback.

( *** ) AUTHORISATION does not necessarily reflect a successful authorisation, see success in the Notification fields table to know more.

Response

Our server expects the following response value, square brackets included:

[accepted]

When our server receives this response to a sent notification message, all notification items in that message are marked as successfully sent.

Our server needs to receive an [accepted] response within 10 seconds, and there should be no interruptions or breaks in the process.
Therefore, we recommend that you handle accepting and replying to notifications separately from processing them, and that you generate an [accepted] response when a notification is stored.

Reply-to URL

In the Adyen Customer Area (CA) you can configure the reply-to URL to send notification responses to, and the necessary authentication details.

You can test your configuration to verify that your server can correctly receive our notifications.

If you receive a notification message that you cannot handle, either because the original transaction is not recognised or because of an unknown  eventCode, you should accept the message and store the item, or at least log it.
If you do not accept the message, the notification process is suspended. To resume it, you need to accept the message.

At-least-once delivery

If the notification delivery fails, or in case it is not possible to determine whether the message was delivered successfully or not, notifications are sent multiple times. This at-least-once delivery rule means  that you may receive the same notification multiple times.

Retries

Whenever a successful response is not explicitly received, notifications are sent multiple times at regular, increasing time intervals:

  • 2 minutes
  • 5 minutes
  • 10 minutes
  • 15 minutes
  • 30 minutes
  • 1 hour
  • 2 hours
  • 4 hours
  • 8 hours

A system message is displayed in the Adyen Customer Area (CA) after the third unsuccessful attempt, i.e. after 2 + 5 + 10 = 17 minutes.
Then, the system continues retrying every 8 hours during the following 7 days.

If you want to trigger a resend attempt, you can send a test notification to yourself:

  • In the Adyen Customer Area (CA), go to Settings | Server Communications.

If the operation is successful, all queued notifications are resent.
Otherwise, you get an overview of the current errors our system has recorded until then.

Disabling notifications

If you disable the notification endpoint, Adyen will store notifications for you until you re-enable the endpoint again. If you re-enable the endpoint, all pending notifications will be sent, including any duplicates that may arise from configuring more than one endpoint.

Duplicate notifications

Due to the structure of the Adyen platform, an authorisation notification may be sent twice.
Duplicate notifications have the same corresponding values for the eventCode and pspReference fields.
If you receive a duplicate notification whose success field is set to true, it overrides and supersedes the previous identical notification.
In all other cases, you do not need to take any action on duplicate notifications.

The following code examples show notification message requests you can receive from Adyen, and the responses you need to send back to us to confirm that you accepted the corresponding notifications. Examples are in JSON, FORM, and SOAP.

Hash-based Message Authentication Codes ( HMAC) can be used as an extra layer of security for data verification and message authentication for notifications. Using the HMAC, the notification recipient can be certain that the transaction variables have not been altered by a malicious third party.

Furthermore, the identity of the sender can be confirmed through a shared key that only the host (Adyen) and the client (you) have stored.

Buckets for Notification Messages

The notification system is an integral part of the Adyen payment platform. When new features are added, the notifications may change due to additional variables being added to the system. In order to maintain backwards compatibility, the fields in notifications are divided into three buckets.

This bucket holds the variables that define the state of a transaction. The uniqueness of the payment and the state of the transaction as reflected on the shopper statement is determined by the variables in this bucket, the entire bucket is signed as the notification HMAC.

The following variables are signed:

  • pspReference
  • originalReference
  • merchantAccountCode
  • merchantReference
  • amount -> value
  • amount -> currencyCode
  • eventCode
  • success

This bucket holds the variables that characterize the payment in terms of risk, fraud, and conversion. Every notification has different characteristics. These variables are not critical to the payment state and typically used for analysis and categorisation.

The fields in this bucket are not signed as part of the notification HMAC.

  • bin
  • last4digits
  • paymentMethod
  • rawAcquirerResult
  • reason
  • risk result
  • shopperInteraction
  • subvariant
  • live

This bucket holds the remaining notification variables, mostly meta-data variables, and variables provided by the merchant. These variables are not critical to the payment state and/or already known to the merchant.

For this reason, this bucket is excluded from the notification HMAC.

  • additional information (/ custom information)
  • eventDate
  • issuerCountryCode
  • operations
    ** any new, non-critical fields **
