We reviewed all the API Docs and still have this question:
We are working on an Hybrid App. Basically its web pages served by the app. Its still an app downloadable from the store but the code beyond authentication is not Xamarin.
Situation: We have our iPad/tablet on which both the app will be installed. This is only active for our employees who will login and set it up as self-pay kiosk.
According to the Point of Sale API Flow on https://developer.squareup.com/docs/pos-api/how-it-works, we are able to follow upto #5. What is confusing is how does the Square app can invoke the mobile web app back? When the button click happens, that JS is waiting for the call to complete with no return values.. And the callback URL will go back to the website and not the Mobile Web app.
This is the confusing part..
