View payment status on a terminal
Open the menu on your device:
On a non-Android terminal, open the Transactions menu > Transactions. On an Android terminal, select Transactions > History.
The terminal will display a list with the last 100 processed transactions on the device. Each transaction shows its current status (Approved, Refused, Canceled). You can click on the payment to see more details about the transaction.
View payment status in the cash register system
Every cash register system is different. Please reach out to your cash register provider for instructions on how to cancel an ongoing transaction with their system.
If you're a cash register provider and wish to implement the cancel option into your Adyen integration then consult this page.
