Cancel Authorization

POST 
/api/v1_0/cards/payment/:transaction_id/cancellation

Cancel (void) a card authorization that has not been fully captured yet, releasing the held funds. Supports full cancellation (omit amount) and partial cancellation. Only the uncaptured remainder can be cancelled.

Authentication: the request must be signed with the service Hash key - sha256(cancellation|service|transaction_id|amount|hash). The payment ID alone is not enough (the payer knows it too); without a valid checksum the request fails with HTTP 401 before anything happens.
