Payment request

This table lists the fields to be passed in an HPP payment request.

Field		Type	Description
`allowedMethods`		String	A comma-separated list of the allowed payment methods to filter the payment method options that would normally be available through the skinned HPP. Only the listed payment methods are shown, if available; all other payment methods are ignored. Spaces are not allowed. If you do not include this optional parameter, the corresponding value in the `merchantSignature` computation is an empty string.
`blockedMethods`		String	A comma-separated list of the not allowed payment methods to filter the payment method options that would normally be available through the skinned HPP. The listed payment methods are not made available on the HPP. Spaces are not allowed. If you do not include this optional parameter, the corresponding value in the `merchantSignature` computation is an empty string.
`brandCode`		String	Defines the specific payment method used to process the payment. This field is required in a payment request call to `skipDetails.shtml` to skip the payment method selection. The `brandCode` values are case sensitive. For information on available `brandCode` values, refer to Payment methods overview .
`captureDelayHours`		Int	The delay between the authorisation and scheduled auto capture, specified in hours.
`countryCode`		String	By default, the payment methods offered to a shopper are filtered based on the country the shopper's IP address is mapped to. In this way, shoppers are not offered payment methods that are not available in the country they are carrying out the transaction from. This IP-to-country mapping is not 100% accurate, so if you have already established the country of the shopper, you can set it explicitly in the `countryCode` parameter. The `country` value format needs to adhere to the ISO 3166-1 alpha-2 standard. An invalid country code results in a transaction/request rejection. You can look up country codes on the ISO website. This field may be required in a payment request call to `directory.shtml` to perform a directory lookup.
`currencyCode`		String	The three-character ISO currency code.
`issuerId`		String	Defines the specific issuer ID used to process the payment. This field is required for iDEAL payments.
`merchantAccount`		String	The merchant account identifier you want to process the (transaction) request with.
`merchantReference`		String	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.
`merchantReturnData`		String	This field value is appended as-is to the return URL when the shopper completes, or abandons, the payment process and is redirected to your webshop. Typically, this field is used to hold and transmit a session ID. Maximum allowed character length: 128 characters. If by including `merchantReturnData` in a request causes it to exceed the allowed maximum size, the payment can fail.
`merchantSig`		String	The signature in Base64 encoded format. It is generated by concatenating the values of payment session fields, and by computing the HMAC using the shared secret, as configured in the skin. For more information, refer to HMAC signature calculation.
`metadata`		Class	Metadata consists of entries, each of which includes of key and value. Limitations: Error "177", "Metadata size exceeds limit"
	`Key`	String	Key for the information to be provided. Example: key = 'storeCountry' Limitations: Error "178", "Metadata key size exceeds limit"
	`value`	String	Information value. Example: value = 'US' Limitations: Maximum length: 80 characters, the value is truncated to 80 characters with '...' appended to it.
`offset`		Int	An integer value that adds up to the normal fraud score. The value can be either a positive or negative integer.
`orderData`		String	An HTML fragment containing the order details to display to the shopper on the payment review page, just before the shopper proceeds to the final order confirmation. Data is compressed and encoded in the session to prevent data corruption, for example in case the locale is set to non-Latin character sets. Compression: GZIP Encoding: Base64
`paymentAmount`		Int	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.
`resURL`		String	Defines the result URL, i.e. the default result landing page shoppers are redirected to when they complete a payment on the HPP. 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.
`sessionValidity`		String	The payment deadline; the payment needs to occur within the specified time value. This is especially useful for tickets and reservations, where you want to hold items for sale for a short, limited period of time. Format: ISO 8601; YYYY-MM-DDThh:mm:ssTZD Example: 2017-07-17T13:42:40+01:00
`shipBeforeDate`		String	The date within which the ordered goods or services need to be shipped or provided to the shopper. This field is also used to set the expiration date of an offline payment like boletos and 7 eleven. Format: ISO 8601; YYYY-MM-DDThh:mm:ssTZD Example: 2017-07-17T13:42:40+01:00
`shopperEmail`		String	The shopper's email address. We recommend providing this information, as it is used in velocity fraud checks. Depending on your integration this field may be mandatory for you, check with the Support Team.
`shopperLocale`		String	locale = language code + country code It specifies the language to use during the transaction. For example: `en_GB` sets the locale preferences to British English. When it is not necessary to include the country-specific part, use only the language code. For example: `it` instead of `it_IT` to set the locale preferences to Italian. If not specified, the locale preference is set to `en_GB` by default.
`shopperReference`		String	A unique identifier for the shopper, for example, a customer ID. We recommend providing this information, as it is used in velocity fraud checks. It is also the key in recurring payments. This field is mandatory in recurring payments.
`shopperStatement`		String	Set this field in your payment request if you want to include a variable shopper statement. You can include placeholders for the references. For example: `${reference}` for the merchant reference `${pspReference}` for the PSP reference. Note: Not all acquirers support dynamic shopper statements. Maximum allowed character length: 135 characters. For Visa/Mastercard: 25/22 respectively. Allowed characters: a-zA-Z0-9.,-?\| If you set the `shopperStatement` field, it is included in the HMAC calculation. Not supported for all payments methods, for further information contact Support Team.
`skinCode`		String	A unique code to identify the skin you want to apply to the HPP in use to process the transaction. Note: You can skin your hosted payment page to make it consistent with your brand look and feel. You can create multiple skins in your merchant account to provide tailored branding experiences to your shoppers.

Payment response

This table lists the fields to be passed in an HPP payment response.

Field	Type	Description
`additionalData.acquirerReference`	String	This field is returned for open invoice in the result URL.
`authResult`	String	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.
`merchantReference`	String	The reference you assigned to the original payment.
`merchantReturnData`	String	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 back office. 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.
`merchantSig`	String	The signature in Base64 encoded format. It is generated by concatenating the values of payment session fields, and by computing the HMAC using the shared secret, as configured in the skin. For more information, refer to HMAC signature calculation.
`paymentMethod`	String	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.
`pspReference`	String	Adyen's 16-character 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 `PENDING`, `ERROR` or `CANCELLED`, the `pspReference` may not yet be known; therefore, it may be empty or not included.
`reason`	String	Only applicable for iDEAL payment method. If a shopper cancels a payment, this field returns a random number. If the transaction results in an error, this field returns either of the possible following values: authentication_error format_error invalid_field invalid_request invalid_amount system_failure unknown_account unknown_error unknown_id
`shopperLocale`	String	The `shopperLocale` value provided in the payment request. If no value is specified in the request, the default value `en_GB` is returned.

They are visible in the Customer Area when either a `billingAddressType` value is provided, or when Billing Address Fields (AVS) is configured for a skin.

Risk fields

Adyen's API for payment requests contains several optional fields that can be provided by the merchants.
