I have what seems to be an uncommon situation. I need to accept payments on my website and send them to various merchants that do their business though my app.
So the payment flow is:
Payer -> My App -> My Customer
This flow seems to be exactly facilitated by paypal's adaptive payments api and while I have pored over all their integration guides, there doesn't seem to be any documentation for even simple email to account verification.
My question is, how can I verify that an email belongs to a verified paypal business account, or perform some other hand shake verification? Is there a way to do that, or even a good workaround? Thanks!
