If I create my own app, can I get a user to authenticate their Venmo/PayPal OR allow access to their Venmo/PayPal, so that their balance shows up on their account on my app?
I want to be able to pay users within my app, and have their Venmo/PayPal balance reflect that change. Without them needing to leave my app to check their Venmo / PayPal app to see if the payment arrived.
Venmo might have a similar API: https://venmo.com/docs/users/ (this shows a access_balance permission). Not familiar with it though.
PayPal's API also provide you with their transactions to search through so you might be able to actually verify/highlight your payment directly.
