In my web app (PHP) the user should be able to connect his paypal account and every time he sold a product from our catalog we will charge him the price. Since the user might sell lot of products I want to make the payment part automatically so he won't have to approve every transaction.
Unfortunately I don't find a way to do this with Paypal SDK.
Currently the app is using the OAuth flow so the user is redirected to Paypal from where I get the access_token for him.
Question: Having the access_token for an user how can I create a (background) payment without the Paypal redirect?
Thank you
