I am using intent to fire up my custom tender app. I am using clover mini 2 and a merchant facing setup. So the flow is:
1.A sale amount is entered in the sale app.
2.The payment option button for my custom tender is pressed.
3.The payment completes in my custom tender app and it returns to sale app.
4.Sale app shows the transaction is completed and shows "Done" and "Void" button at side.
My actual question is, when the "Void" button is pressed, how to let my custom tender app know that the transaction has been voided? Is there any intent for it?
