Card unbinding

To unbind a card from recurring (CoF) payments using JSON API, use the following request.

When working with HTML forms, the request to unbind a card from recurring (CoF) payments must consist of the following set of fields:

wsb_version
wsb_seed
wsb_storeid
wsb_customer_id
wsb_operation_type
wsb_recurring_token
wsb_signature

The wsb_signature parameter is calculated by concatenating the following fields into a single string:

wsb_seed
wsb_storeid
wsb_customer_id
wsb_operation_type
wsb_recurring_token
SecretKey

The concatenation order of the fields must not be violated. Then, depending on the specified protocol version (wsb_version), the MD5 (if the version is not specified) or SHA1 (for version 2) of the concatenated string is calculated.
