We need a notificationsystem for our QR Code payment Method on the App.
The website generates an invoice, which the app can fetch and we need a notification for the final payment.
Client buys something
Website generates QR Code
App shows Invoice+QR Code
Client scans QR Code and is transfered to his banking app
AND HERE we need a notification on the App after the client has made the payment
Its a native app on android
[login to view URL]
This is our qr source code which we implemented, and this sends the user to his banking app, where he can make the payment. But our current developers are not able to implement the notification part. So thats why you come into the process. Can you check, if there is a way in the source code to transfer the notification data to the app from the qr code invcoice?
We have admin (me) merhcant (business client from me) and user side
User need to pay invoice of our business client
you basically need to only make the function of notification nothing else.
