Sometimes, during an ongoing transaction
process, the PayServer asks you to do some additional actions, e.g., ask the
shopper for a signature. When this happens the ongoing process stops and will not
continue until you submit the correct message or, potentially, abort the process.
In this case the PayServer is
asking you to submit the customer's signature. You can do this by making a
, in which you can either
submit a digital signature or tell the transaction process that the shopper will
sign the printed receipt. To keep the standard request-response flow, the
PayServer responds to this by sending a
, which can have
in case something was wrong with the request.
The diagram below shows a transaction with signature sequence message flow.
Abort a Transaction During Action
When the PayServer indicates an
action, you can also respond with a normal abort flow. The diagram below shows a
transaction aborted on signature action sequence message flow.
