I'm developing a delivery app and want to implement paypal to payment options. I'm having difficulty to find the correct API topic that would fit with what I want.
For example, I want the user to add the paypal as payment method, "accepting the application" and from there, I have permission to make payments on his behalf (the same as what happens in Uber).
I can already authorize the user in the application by making a request for http://www.sandbox.paypal.com/signin/authorize and then https://api.sandbox.paypal.com/v1/oauth2/token. I get an access_token, but don't know if this is the correct way.
I have already lost a few days reading the library and I still have no solution.
