Callback in "payment successful" case (iframe and host-2-host)

If the payment is successful, the payment data will be sent to the process_url store server using the POST method:

Callback contains the fields:

Field	Description
co_inv_id	unique transaction number;
co_inv_crt	transaction creation date and time;
co_inv_prc	transaction processing date and time;
co_inv_st	payment processing status (“success”);
co_order_no	transaction number in the merchant system (transferred by the merchant when payment is making);

co_cur	transaction currency;
co_merchant_id	unique merchant number;
co_merchant_uuid	unique merchant ID;
co_sign	digital signature with the merchant’s key (for more details read the “Digital signature in callback” section);
co_card_number	transfer of the card mask. This field is not present in the response by default. In order to receive it in response, you must set YES in the field Cardmask in callback in the merchant’s settings;
co_error_resolution	payment error description.

If an internal conversion is performed, additional fields may be present in the callback:

Field	Description
co_base_amount	the base amount received in the request;
co_base_currency	the base currency used in the payment request;
co_rate	conversion rate.

During the converting, the co_cur field will include the processing currency, and the co_amount and co_to_wlt fields will include the amounts in the processing currency.

In response to the package received, the merchant’s server must respond with two English letters OK.
