I created a Web app for REST API on Clover sandbox environment. My app id is JTMD54WMQH4JT on same developer account i created 3 merchants and authorize that all 3 merchant and it works.
But when i done same authorization process with another sandbox merchant account then it shows NO Found error. I searched for this and it shows that merchant need to install my Webapp first.
So, another question is how we can ask Merchant to Install this app or that one will handle by Auth API itself?
