​
Successful Transaction

Pay Connect client creates a transaction, the terminal processes payment, then the client retrieves the outcome via polling or webhook.

​
Transaction Cancel

Pay Connect client cancels a transaction. If the transaction is still INITIATED it is cancelled immediately. If IN_PROGRESS, a cancel signal is sent to the terminal.

​
Transaction Success & Revert

After a successful transaction, the Pay Connect client requests a revert (void). The terminal processes the revert asynchronously. The client polls the operation status.

​
Transaction Success & Refund

After a successful transaction, the Pay Connect client requests a partial or full refund. A new refund transaction is created and processed by the terminal.

​
