All documentation I can find for PayPal development is focused on capturing payments from a customer. Even IPN and Webhook events are all about taking action when payments are received.
I operate a small press and my primary use of PayPal is to send payments to authors. I need to take certain actions when payment is sent from my PayPal account to many different recipients.
Using any PayPal API, how do I programmatically retrieve a list of recent payments I have sent? Alternatively, how can I receive a webhook notification when I send a payment through PayPal instead of when I receive one?
