Payment Options Inquiry

Request to retrieve the options available for processing a payment, for example, the credit cards and currencies.

You can also use this operation to perform a Rate Quote for Dynamic Currency Conversion or to calculate the applicable Surcharge for an order.

Warning! This operation must not be called directly from the browser, as it would reveal the integration password to customers.

This operation may not be needed if such values rarely change and can be hard-coded into the website handling the transaction. However, the operation is useful for populating and validating transaction fields (for example) if these values can change in real time for a business's website.

If the operation is called with no parameters, all values that could apply for all fields are returned: all of the possible currencies, all of the possible card types, and so on. Non-complex websites can use this unmodified data set for building a website's presentation and input validation.

Some websites require more complex configuration (for example, where USD and EUR currencies are supported on MasterCard and Visa, but only USD on American Express). Call the operation with parameters to restrict the returned values. If a sourceOfFunds.provided.card.prefix is passed in, only currencies applicable to the card brand identified by the prefix are returned. If an order.currency is passed in, only payment options applicable for that currency are returned.

A language identifier or IETF language tag to control the language of the payment interaction with the payer (e.g. en_US, es, fr-CA).

By default, the language is determined from your configuration. Supply a value for this field only if you wish to override the default behavior. If the language you specify is not supported by the gateway, the payment is displayed in the best matching language.

See Dynamic Currency Conversion for more detail.

Min length: 2 Max length: 5
session.id ASCII Text OPTIONAL

Identifier of the payment session containing values for any of the request fields to be used in this operation.

Values provided in the request will override values contained in the session.

Data consists of ASCII characters

Min length: 31 Max length: 35
session.version ASCII Text OPTIONAL

Use this field to implement optimistic locking of the session content.

Do this if you make business decisions based on data from the session and wish to ensure that the same data is being used for the request operation.

To use optimistic locking, record session.version when you make your decisions, and then pass that value in session.version when you submit your request operation to the gateway.

If session.version provided by you does not match that stored against the session, the gateway will reject the operation with error.cause=INVALID_REQUEST.

See Making Business Decisions Based on Session Content.

Note:

  • You can only override the default value if you have the requisite permission.
