I'm using paypal's rest API
https://developer.paypal.com/webapps/developer/docs/api/
Whenever I use API to fetch orders etc I need a id and secret key to request access token. Then I can fetch them.
I'm thinking is there anyway to get the id and secret key via OAuth? Just like storenvy.com does. They connect with paypal login. Then fetches the orders / transactions.
Any idea?
