Introducing Web v6

Improvements

The Web v6 library introduces the following improvements:

  • Reduced bundle size through tree shaking
  • Enhanced design
  • Enhanced Typescript developer experience
  • Better alignment of express payment methods
  • Added support for 6 localizations
  • Support for Apple Pay Order tracking
  • Improve AVS checks for Google Pay and Apple Pay

To update your existing integration, see Migrate to Adyen Web v6.

How it works

From an implementation perspective, a Drop-in integration contains:

  • Server-side: a single API call which creates the payment sessions.
  • Client-side: Drop-in, which uses the payment session data to make the payment request and to handle any other actions like redirects or 3D Secure authentication.
  • Webhook server: receives webhook notifications which tell you what is the outcome of each payment.

If you need to handle additional use cases, you need to implement additional endpoints and client-side configuration.

Integration steps

To integrate Drop-in in your web application:

  1. Install an API library on your server.
  2. Create a session from your server.
  3. Install the Adyen Web library on your front end.
  4. Create a DOM element for Drop-in.
  5. Configure and create an instance of AdyenCheckout.
  6. Configure and create an instance of Drop-in.
  7. Handle redirects.
  8. Show the payment status to your shopper.
  9. Update your order management system.
  10. Test your integration and go live.

Payment flow

The payment flow is the same for all payments:

  1. The shopper goes to the checkout page.
  2. Your server uses the shopper's country and currency information from your client to create a payment session.
  3. Your client creates an instance of Drop-in using the session data from the server.
  4. Drop-in shows the available payment methods, collects the shopper's payment details, handles additional actions, and presents the payment result to the shopper.
  5. Your webhook server receives the notification containing the payment outcome.

Requirements

Before you begin to integrate, make sure you have followed the Get started with Adyen guide to:

  • Get an overview of the steps needed to accept live payments.
  • Create your test account.

After you have created your test account:

Install an API library

We provide server-side API libraries for several programming languages, available through common package managers, like Gradle and npm, for easier installation and version management. Our API libraries will save you development time, because they:

  • Use an API version that is up to date.
  • Have generated models to help you construct requests.
  • Send the request to Adyen using their built-in HTTP client, so you do not have to create your own.
Try our example integration

Requirements

  • Java 11 or later.

Installation

You can use Maven, adding this dependency to your project's POM.

import java.io.IOException;
public class Snippet {
public Snippet() throws IOException, ApiException {
// Set up the client and service.
Client client = new Client("ADYEN_API_KEY", Environment.TEST);
}
}

Create a session

A payment session is a resource with information about a payment flow initiated by the shopper. This resource has all the information required to handle all the stages of a payment flow. You can configure this resource with information like available payment methods, payment amount, or line items.

To create a payment session, make a /sessions request, including:

Parameter name Required Description
merchantAccount -white_check_mark- Your merchant account name.
amount -white_check_mark- The currency and value of the payment, in minor units. This is used to filter the list of available payment methods to your shopper.
returnUrl -white_check_mark- URL to where the shopper should be taken back to after a redirection.
If the URL to return to includes non-ASCII characters, like spaces or special letters, URL encode the value.
The URL must not include personally identifiable information (PII), for example name or email address.
reference -white_check_mark- Your unique reference for the payment. Minimum length: three characters.
countryCode The shopper's country code. This is used to filter the list of available payment methods to your shopper. If not set, setting the locale is required in the front-end global configuration.
channel The platform where the payment is taking place. Use Web.
expiresAt The session expiry date in ISO8601 format, for example 2023-11-23T12:25:28Z, or 2023-05-27T20:25:28+08:00. When not specified, the expiry date is set to 1 hour after session creation. You cannot set the session expiry to more than 24 hours after session creation.
shopperLocale The language that the payment methods will appear in if the locale in your front-end global configuration isn't set. Set it to the shopper's language and country code. The default is en-US.
shopperEmail The shopper's email address. Strongly recommended because this field is used in a number of risk checks, and for 3D Secure.
shopperReference Your reference to uniquely identify this shopper. Strongly recommended because this field is used in a number of risk checks.
applicationInfo If you are building an Adyen solution for multiple merchants, include some basic identifying information, so that we can offer you better support.

Here is an example of how to create a session for a payment of 10 EUR:

}

API error handling

If you do not get an HTTP 201 response, use the errorCode field and the list of API error codes to troubleshoot.

Prepare your front end

Use Drop-in to show the available payment methods, and to collect payment details from your shoppers.

Install Adyen Web

Use the Adyen Web npm package, or embed the Adyen Web script and stylesheet into your HTML file:

We offer two ways of importing with npm:

Drop-in resources are available on the window global variable.

Create a DOM element for Drop-in

Create a DOM container element on your checkout page where you want Drop-in to be rendered and give it a descriptive id. We strongly recommend that you do not put it in an iframe element, because it may cause issues.

Copy link to code block
Copy code
Copy code
<div id="dropin-container"></div>

If you are using JavaScript frameworks such as Vue or React, make sure that you use references instead of selectors and that you do not re-render the DOM element.

Create Drop-in

Drop-in consists of:

  • AdyenCheckout: represents one payment session.
  • Dropin: represents the interface where a shopper completes their payment.

With the AdyenCheckout instance, you can create a Dropin instance.

Create your instance of AdyenCheckout

Create a global configuration object that you use to create the instance of AdyenCheckout. The object contains configuration parameters and event handlers.

  1. Add configuration parameters.

    Parameter name Required Description
    session -white_check_mark- The payment session object from your call to /sessions. Contains a session.id and session.sessionData.
    environment -white_check_mark- Use test. When you are ready to accept live payments, change the value to one of our live environments
    amount -white_check_mark- An object representing the amount to be displayed on the Pay Button. Its properties are value (the amount in the currencies smallest unit, for example cents for EUR) and currency.
    countryCode -white_check_mark- The shopper's country code. This is used to filter the list of available payment methods to your shopper.
    locale -white_check_mark- The language used in the Drop-in UI. For possible values, see the list of available languages.
    By default, this is the either the shopperLocale from your /sessions request or, if this locale is not available on Drop-in, en-US.
    showPayButton Shows or hides a Pay Button for each payment method. Defaults to true.
    When set to false, you must override it in paymentMethodsConfiguration .
    The Pay button triggers the onSubmit event when payment details are valid. If you want to disable the button and then trigger the submit flow on your own, set this to false and call the .submit() method from your own button implementation.
    PayPal Smart Payment Buttons doesn't support the .submit() method.
    secondaryAmount Shows the payment amount in an additional currency on the Pay button. You must do the currency conversion and set the amount.
    This object has properties:
  2. Add event handlers, to handle events that get triggered during the payment.

    Event handler name Required Description
    onPaymentCompleted(result, component) -white_check_mark- Create an event handler, called when the payment is completed.
    onPaymentFailed(result, component) -white_check_mark- Create an event handler, called when the payment failed. A failed payment has result code Cancelled, Error or Refused.
    onError(error) Create an event handler, called when an error occurs in Drop-in.
    beforeSubmit(data, component, actions) Create an event handler, called when the shopper selects the Pay button. Do not use if you are implementing an additional use case.
    Allows you to add details which Drop-in will send in the payment request to Adyen's servers. For example, you can add shopper details like billingAddress , deliveryAddress , shopperEmail , or shopperName . When the beforeSubmit event is triggered, you need to continue or stop the payment flow using methods available in the event handler:
    • Continue the payment flow (actions.resolve()): You should call the actions.resolve() method regardless of the resultCode, including when the payment is unsuccessful.
    • Stop the payment flow (actions.reject()): Stop the payment flow only when your server-side API request to Adyen failed, or when experiencing network connection issues.
    onSubmit(state, component, actions) Required if you need to update the payment amount after rendering Drop-in. For this additional use case, you need to integrate additional endpoints.
    Creates an event handler, called when the shopper selects the Pay button and payment details are valid.
    When the onSubmit event is triggered, you need to continue or stop the payment flow using methods available in the event handler:
    • Continue the payment flow (actions.resolve()): You should call the actions.resolve() method regardless of the resultCode, including when the payment is unsuccessful.
    • Stop the payment flow (actions.reject()): Stop the payment flow only when your server-side API request to Adyen failed, or when experiencing network connection issues.
    onActionHandled Create an event handler, called when an action, for example a QR code or 3D Secure 2 authentication screen, is shown to the shopper. The following action.type values trigger this callback:
    • threeDS
    • qr
    • await
    Returns data that contains:
    • componentType: The type of component that shows the action to the shopper.
    • actionDescription: A description of the action shown to the shopper.
    onAdditionalDetails(state, component, actions) Required if you need to confirm an additional action on your server. For this additional use case, you need to integrate additional endpoints.
    Create an event handler, called when a payment method requires more details, for example for native 3D Secure 2, or native QR code payment methods.
    onChange(state, component) Create an event handler, called when a change happens in the payment form.

    If an error occurs, the onError event returns an object which contains details about the error:

    Error field Description
    error.name The type of error. Use the values it returns to configure localized error messages for your shoppers:
    • NETWORK_ERROR: a call that Drop-in made to the server has failed, for example because of a timeout, or if there is missing information in the request. Ask the shopper to try again.
    • CANCEL: the shopper cancelled the payment. Only applies for payment methods that allow explicit cancellation in the UI, for example Apple Pay or PayPal.
    • IMPLEMENTATION_ERROR: the method or parameter is incorrect or not supported.
    • ERROR: generic catch-all error. Tell the shopper something went wrong and ask them to try paying again, maybe with a different payment method.
    error.message Gives more information for each type of error. The message is technical so you shouldn't show it to your shoppers.
    For error.name: NETWORK_ERROR, the information in the message field depends on the environment:
    • test: you get a message with a generic error code to help you troubleshoot.
    • live: the message from the response.
    component The name of the variable where you created the instance of Drop-in, for example dropinComponent.

    The error object may contain additional fields inherited from the Error() constructor.

    Combine the configuration parameters and event handlers into your global configuration object.

    },
    environment: 'test', // Change to 'live' for the live environment.
    amount: {
    value: 1000,
    currency: 'EUR'
    },

    onPaymentCompleted: (result, component) => {
    console.info(result, component);
    },
    onPaymentFailed: (result, component) => {
    console.info(result, component);
    },
    onError: (error, component) => {
    console.error(error.name, error.message, error.stack, component);
    }
    };
  3. Use this global configuration object to create an instance of AdyenCheckout.

    Copy link to code block
    Copy code
    Copy code
    // All of the resources that you imported are properties of the window.
    // In this example you imported Card, GooglePay, and Paypal individually.
    const { AdyenCheckout, Dropin, Card, GooglePay, PayPal } = window.AdyenWeb;
    const checkout = await AdyenCheckout(globalConfiguration);

Create your instance of Drop-in

  1. Create another configuration object for Drop-in. You can add the following configuration:

    Parameter name Required Description
    paymentMethodComponents If you imported Drop-in with individual payment methods. An array of the payment methods that you imported. For example: [Card, PayPal, GooglePay, ApplePay, Ideal].
    paymentMethodsConfiguration Configuration for individual payment methods. The payment method page for the individual payment method shows required and optional configuration.
    If you include this in the configuration on your instance of Dropin, it overrides global payment method configuration on your instance of AdyenCheckout.
    openFirstPaymentMethod When enabled, Drop-in opens the first payment method automatically on page load. Defaults to true.
    openFirstStoredPaymentMethod When enabled, Drop-in opens the payment method with stored card details on page load. This option takes precedence over openFirstPaymentMethod. Defaults to true.
    openPaymentMethod.type Automatically selects the specified payment method when Drop-in renders. Set the payment method type that you want to be automatically selected as the value.
    showStoredPaymentMethods Shows or hides payment methods with stored card details. Defaults to true.
    showRemovePaymentMethodButton Allows the shopper to remove a stored payment method. Defaults to false.
    If using this prop, you must also implement the onDisableStoredPaymentMethod callback.
    showPaymentMethods Shows or hides regular (not stored) payment methods. Set to false if you only want to show payment methods with stored card details. Defaults to true.
    paymentMethodsConfiguration Configuration for individual payment methods. The payment method guides have configuration options specific to each payment method.
    If you include this in the configuration on your instance of DropIn, it overrides global payment method configuration on your instance of AdyenCheckout.
    redirectFromTopWhenInIframe If your Drop-in is inside of an iframe element, set to true if you want redirects to be performed on the top-level window.
    We recommend that you do not put Component in an iframe.
    instantPaymentTypes Moves payment methods to the top of the list of available payment methods. This is available for Apple Pay and Google Pay.
    disableFinalAnimation When enabled, disables the final animation after a shopper completes the payment (whether successful or failed). This lets you implement your own Defaults to false.
    showRadioButton When enabled, payment methods in the Drop-in have a radio button. Defaults to false.
  2. Optionally add event handlers.

    Event handler name Description
    onReady() Called when Drop-in is initialized and is ready for use.
    onSelect(component) Called when the shopper selects a payment method.
    onDisableStoredPaymentMethod(storedPaymentMethodId, resolve, reject) Called when a shopper removes a stored payment method. To remove the selected payment method, make a /disable request using the storedPaymentMethodId. Then call either resolve() or reject(), depending on the /disable response.
    Drop-in configuration (when importing individual payment methods)

    const dropinConfiguration = {
    // Required if you import individual payment methods.
    paymentMethodComponents: [Card, PayPal, GooglePay, ApplePay, Ideal],
    // Optional configuration.
    onReady: () => {},
    instantPaymentTypes: ['applepay', 'googlepay']
    };
  3. For some payment methods, you must add additional configuration. You can also add optional configuration for some payment methods. For example, you can add additional configuration for cards.

    Payment method configuration

    card: {
    // Optional configuration.
    hasHolderName: true, // Show the cardholder name field.
    holderNameRequired: true, // Mark the cardholder name field as required.
    }
    }
    }

    Configuration for payment methods overrides global configuration. In the following example, the onError() configuration for card overrides the global onError() configuration.

    Override global configuration
    Expand view
    Copy link to code block
    Copy code
    Copy code
    // The global configuration object.
    const globalConfiguration = {
    // Global configuration for onError.
    onError: () => {}
    }
    // Drop-in configuration.
    cons dropInConfiguration = {
    // Configuration for individual payment methods.
    paymentMethodsConfiguration: {
    card: {
    // onError configuration for card payments. Overrides the global configuration.
    onError: () => {}
    }
    }
    };
  4. Create an instance of Drop-in, passing the instance of AdyenCheckout and the Drop-in configuration object that you created. Then mount the Drop-in to the DOM element you created.

    Create an instance of Drop-in
    Expand view
    Copy link to code block
    Copy code
    Copy code
    const dropin = new Dropin(checkout, dropinConfiguration).mount('#dropin');

The following methods are available on your instance of Drop-in:

Method name Description
mount(selector) Mounts the Drop-in into the DOM returned by the selector.
The selector must be either a valid CSS selector string or an HTMLElement reference.
unmount() Unmounts the Drop-in from the DOM. We recommend to unmount in case the payment amount changes after the initial mount.
closeActivePaymentMethod() Closes a selected payment method, for example if you want to reset the Drop-in.
update() Updates the properties and remounts Drop-in into the DOM, for example, if you want to change the properties of the configuration object after Drop-in is mounted.

Drop-in orders the payment methods by popularity, the most popular payment methods in the shopper's country appearing at the top.

In your Customer Area, you can configure which payment methods are rendered based on the shopper's country. If you want to customize rendered payment methods for specific transactions, you can do this on the server side.

Customize based on shopper's country

To configure which payment methods are rendered (and in which order) based on the shopper's country:

  1. Log in to your Customer Area.

  2. Go to Settings > Checkout settings.

    If Checkout settings does not appear in the Settings menu, ask your admin user to give you the Change payment methods user role.

  3. Select a Shopper country.

  4. Drag the payment methods into the order you want them to appear to shoppers in this country.

  5. To hide a payment method from shoppers in this country, drag it to the Other configured payment methods box.

Customize for specific transactions (server side)

When making a /sessions request, you can include one of the following parameters:

To refer to payment methods, use their paymentMethod.type from Payment methods overview.

The following example shows how to make a request to only show iDEAL and credit cards in the payment form:

/sessions request
Expand view
Copy link to code block
Copy code
Copy code
curl https://checkout-test.adyen.com/v70/sessions \
-H 'x-api-key: ADYEN_API_KEY' \
-H 'content-type: application/json' \
-d '{
"merchantAccount": "YOUR_MERCHANT_ACCOUNT",
"allowedPaymentMethods": ["ideal", "scheme"],
"countryCode": "NL",
"amount": {
"currency": "EUR",
"value": 1000
},
"channel": "Web",
"shopperLocale": "NL"
}'

Drop-in includes a pre-styled payment form. The styling of fonts, colors, layouts, and buttons can be customized using CSS custom properties to match your website and brand.

You can customize elements that are not inside an iFrame, by overriding the CSS property styles:

  1. Create a CSS file override.css, with the CSS variables you want to style:

    override.css
    Expand view
    Copy link to code block
    Copy code
    Copy code
    :root {
    --adyen-checkout-input-wrapper-focus-border-color: #ff8888;
    }
  2. Import the override.css file after importing the Adyen library's main CSS file:

    Your checkout code
    Expand view
    Copy link to code block
    Copy code
    Copy code
    import '@adyen/adyen-web/styles/adyen.css';
    import './override.css';

Supported languages

We include UI localizations for some languages. The fields and text are in the files for the included locales.

To use a language or localization that isn't included, create your own.

Change the language

The language of the UI is based on the locale set when creating your instance of AdyenCheckout.

If no locale is set when creating an instance of AdyenCheckout, the language displayed matches the shopperLocale from your /sessions request.

If neither language is set or supported, the UI language defaults to US English.

Customize the localization

The text displayed in each localization can be customized, allowing you to replace the default text with your own.

To customize a localization:

  1. Create a translations object on your payments page.

  2. In this object, specify the locale you want to customize, and add key-value pairs corresponding to any text you want to customize.

    The following example shows how to customize the US English (en-US) translation so that:

    • Shipping Address appears instead of Delivery Address (the default en-US text).
    • State appears instead of State or Province (the default en-US text).

    Copy code
    const translations = {
    "en-US": {
    "deliveryAddress": "Shipping Address",
    "stateOrProvince": "State"
    }
    };
  3. To use the customized localization in your payment form, provide the following parameters in the configuration object:

    Parameter name Required Description
    locale -white_check_mark- The locale you customized in the previous step.
    translations -white_check_mark- Use translations

    The following example shows how to use a customized en-US localization in Drop-in.

    Example of US English localization

    Copy code
    Copy code
    const configuration = {
    locale: "en-US",
    translations: translations,
    ...
    };

Create your custom localization

To use a language or localization that we do not included, create your own.

  1. Create a translations object on your payments page.

  2. In this object, specify the locale you want to create. For example, you can use the locale nl-BE to create a Belgian Dutch localization, and add key-value pairs corresponding to text shown in the UI.

    The example below shows a translation object for creating a nl-BE localization.

    British English translations example
    Expand view
    Copy link to code block
    Copy code
    Copy code
    const translations = {
    "nl-BE": {
    "paymentMethods.moreMethodsButton": "Meer betaalmethoden",
    "payButton": "Betaal",
    "storeDetails": "Bewaar voor mijn volgende betaling",
    ...
    }
    };

    The ellipsis (...) in the translations object above indicate the code sample isn't complete. For missing key-value pairs in your configuration, the translation defaults to en-US.

  3. To use your localization in your payment form, provide the following parameters in the configuration object:

    Parameter name Required Description
    locale -white_check_mark- The locale you created in the previous step.
    translations -white_check_mark- Use translations

    The example below shows how to use a created localization for nl-BE.

    Expand view
    Copy link to code block
    Copy code
    Copy code
    const configuration = {
    locale: "nl-BE",
    translations: translations,
    ...
    };
    const checkout = await AdyenCheckout(configuration);

Text direction

The default text direction is left-to-right. Text direction is independent from the locale you set in the configuration object. So even if you set the locale to a right-to-left language, like Arabic, you still need to set the text direction.

To change the text direction to right-to-left, use the HTML dir attribute on the parent element for the checkout container.

Handle the payment

When you create and mount Drop-in, the shopper interacts with the interface to complete the payment. The whole payment flow is handled by Drop-in you configured and created, except for when a redirect happens.

Handle the redirect

Some payment methods, like iDEAL and some 3D Secure flows, will redirect the shopper back to your website. When the shopper comes back to your website, show them the payment result, based on the result code. To get the resultCode, you can either:

  • Create an instance of AdyenCheckout after the redirect, as described below.
  • Confirm the redirect result on your server, for which you need to implement an extra API endpoint.

The shopper comes back to the returnUrl specified when creating the payment session. The returnUrl has query parameters appended to it, which you need to handle the redirect:

  • sessionId: the unique identifier for the shopper's payment session.
  • redirectResult: details you need to submit to handle the redirect.

If the shopper doesn't return to you website, you do not get a redirectResult. You do not need to do anything to handle the redirect in this case. Instead, wait for the webhook that we send to your server.

Example return URL

Copy code
Copy code
// The return URL has query parameters related to the payment session.
https://your-company.com/?sessionId=CSD9CAC34EBAE225DD&redirectResult=X6XtfGC3!Y...

Extract the values from the query string parameters and create a function which handles the redirect result. The function needs to:

  1. Create an instance of Adyen Checkout using the sessionId value you extracted.
  2. Submit the redirectResult value you extracted from the returnUrl.
handleRedirectResult

Copy link to code block
Copy code
Copy code
// Create an instance of AdyenCheckout to handle the shopper returning to your website.
// Configure the instance with the sessionId you extracted from the returnUrl.
const checkout = await AdyenCheckout(configuration);
// Submit the redirectResult value you extracted from the returnUrl.
checkout.submitDetails({ details: { redirectResult: redirectResult } });

If the shopper doesn't return to your website, do not call submitDetails, because the result doesn't change when you attempt the request.

After you submit the redirectResult value, Drop-in calls the onPaymentCompleted(result, component) event. Use the result code in result.resultCode to inform the shopper.

To update your order management system, wait for the webhook that we send to your server.

Get the outcome

Inform the shopper

Depending on whether the payment was successful, the onPaymentCompleted or onPaymentFailed event is triggered.

From the relevant event, you can get the resultCode to inform the shopper about the current payment status.

You can also get the result of the payment session on your server.

  1. Get the id from the /sessions response.
  2. Get sessionResult from the onPaymentCompleted or onPaymentFailed event.
  3. Make a GET /sessions/{id}?sessionResult={sessionResult} request including the id and sessionResult. For example:

    Request for result of payment session
    Expand view
    Copy link to code block
    Copy code
    Copy code
    curl -X GET https://checkout-test.adyen.com/v70/sessions/CS12345678?sessionResult=SOME_DATA

    The response includes the result of the payment session (status). For example:

    Response with result of the payment session
    Expand view
    Copy link to code block
    Copy code
    Copy code
    {
    "id": "CS12345678",
    "status": "completed"
    }

    Possible statuses:

    status Description
    completed The shopper completed the payment. This means that the payment was authorized.
    paymentPending The shopper is in the process of making the payment. This applies to payment methods with an asynchronous flow.
    canceled The shopper canceled the payment.
    expired The session expired (default: 1 hour after session creation). Shoppers can no longer complete the payment with this sessionId.

The status included in the response doesn't get updated. Do not make the request again to check for payment status updates. Instead, check webhooks or the Transactions list in your Customer Area.

Update your order management system

You get the outcome of each payment asynchronously, in an AUTHORISATION webhook. Use the merchantReference from the webhook to match it to your order reference.
For a successful payment, the event contains success: true.

Example webhook for a successful payment
Expand view
Copy link to code block

Copy code
{
"live": "false",
"notificationItems":[
{
"NotificationRequestItem":{
"eventCode":"AUTHORISATION",
"merchantAccountCode":"YOUR_MERCHANT_ACCOUNT",
"reason":"033899:1111:03/2030",
"amount":{
"currency":"EUR",
"value":2500
},
"operations":["CANCEL","CAPTURE","REFUND"],
"success":"true",
"paymentMethod":"mc",
"additionalData":{

"pspReference":"NC6HT9CRT65ZGN82",
"eventDate":"2021-09-13T14:10:22+02:00"
}
}
]
}

For an unsuccessful payment, you get success: false, and the reason field has details about why the payment was unsuccessful.

Test and go live

Before going live, use our list of test cards and other payment methods to test your integration. We recommend testing each payment method that you intend to offer to your shoppers.

You can check the status of a test payment in your Customer Area, under TransactionsPayments.

To debug or troubleshoot test payments, you can also use API logs in your test environment.

When you are ready to go live, you need to:

  1. Apply for a live account. Review the process to start accepting payments on Get started with Adyen.
  2. Assess your PCI DSS compliance by submitting the Self-Assessment Questionnaire-A.
  3. Configure your live account
  4. Submit a request to add payment methods in your live Customer Area .
  5. Switch from test to our live endpoints.
  6. Load Drop-in from one of our live environments and set the environment to match your live endpoints:

    Endpoint region Value
    Europe (EU) live live
    United States (US) live live-us
    Australia (AU) live live-au
    Asia Pacific & Southeast (APSE) live live-apse
    India (IN) live live-in
