The processes of bankcard authorization (payment operation) and financial transaction (financial confirmation) in the double-stage operation mode are split.
Bankcard payment operation
At the first stage, the bankcard is authorized, its credit status is verified and the funds at the client's account are blocked. If the enterprise uses the double-stage operation mode, then, besides the mandatory and additional payment parameters (as described in section "Payment request"), there is a need to send the parameter Delay=1 in the authorization request.
