Extend Payment Request

The guide illustrates how to extend the request sent to Adyen

The payment request to Adyen may be extended with custom attributes via the buildCustomPaymentAttributes property, which is a function that returns the desired attributes along with their values. The attributes will be concatenated to the already built base payload.

The buildCustomPaymentAttributes can be added to the adyen.configuration object inside the middleware.config.js

The basic pattern is the same for all properties.

Here's an example:

{
  adyen: {
    // ...
    configuration: {
      // ...
      buildCustomPaymentAttributes(params) {
        return {
          nameofProperty: [
            "could",
            "be",
            "an",
            "array"
          ],
          additionalCustomProperty: {
            "now": "this one is an object"
          },
          thirdCustomProperty: "can also be a string"
        };
      }
    }
  }
}

Check the Adyen Doc section on Sessions where you can find available properties to add to your payment requests.

Available params

The first argument of the buildCustomPaymentAttributes function called params has the following type:

export type BuildCustomPaymentAttributesParams = {
  payload: CreateSessionRequestPayload;
  payment: PaymentWithFields;
  cart: Cart;
  shopperLocale?: string;
  customerId?: string;
};
