Hi, we are designing our payment system. We will be doing our custom app on the clover mini and use payment connector to do the payments.
My question is, after we issue a call to sale, -- between the steps where the user can tap the credit card and the time that the user hits OK after putting the signature (we will require a signature on the device), Is there a way to cancel this transaction from our code?
To give more context, our payment app (that uses the payment connector), is talking to our backend server where it may get a command telling it to cancel the transaction.
I'm not sure if this is still considered semi-integration or considered to be app market developer platform, but this app will only be used by us and will not be shown in the app market
