Capture Workflow

The capture workflow begins when you send a request for a capture.

The merchant sends a request for a capture to Barclays.

For online captures, Barclays validates the order information then sends an online capture to the payment processor.

For offline captures, Barclays stores the capture request in a batch file and sends the batch file to the payment processor after midnight.

The processor validates the request and forwards it to the issuing bank.

The issuing bank transfers funds to the acquiring bank.
