github.com/plutov/paypal/v3 (go): Package paypal provides a wrapper to PayPal API (https://developer.paypal.com/webapps/developer/docs/api/). The first thing you do is to create a Client (you can select API base URL using paypal contants).  Then you can get an access token from PayPal:  After you have an access token you can call built-in functions to get data from PayPal. paypal will assign all responses to go structures.
