After the customer has submitted credit card data, right before sending this data to the payment gateway, X-Payments connects to the store to verify the cart total and contents.

The HTTP POST request is sent to the callbackURL defined in the Payment initialisation request.

Note: As of API v1.3, the store must respond to this callback request. The response must be an encrypted XML document (i.e. the same way as for other communication between the store and X-Payments).

Data which is received in the POST request from X-Payments

Field Value Type Description
action check_cart fixed string Identifies the check-cart callback request
txnId (mixed) string (MD5 hash) A unique ID of the payment on the side of X-Payments
refId (mixed) string Order ID (or any other reference) in the online store
