Hi,
I'm currently trying to integrate the PayPal Payments API into one of my processes.
At the moment I'm only working in the sandbox environment.
I test this on localhost, so there is no real testing domain.
I'm using the PayPal-PHP-SDK to create the payment and redirect the user to the approval page.
After that, PayPal returns the user to my return url, where I try to execute the Payment.
The Problem is, that I get an error 400 (UNAUTHORIZED_PAYMENT), when just trying to get the Payment from the API. I don't even try to execute it.
Here is the DebugID: b204748d5081
