verification
This postback is intended for Server-to-Server (S2S) API users.
It's used to inform you about the final status of a verification transaction.
This postback will be posted to your Postback URL when verification processes are successful.
If a verification failed then you need to start the payment process again.
If a verification was successfully processed then you need to post the second API call to confirm the transaction that you initiated.
