In implementing a server Paypal integration, the POST Create call works correctly to https://api.sandbox.paypal.com/v1/payments/payment with the response object matching that found in the API. The server successfully returns the result to the Client, and res.id for the .then(res) function of paypal.request.post is: PAY-76T970067E989851JLPLCMKA
After the user authorizes payment, the client sends a request to my server's execute endpoint with a payload of:
{ "paymentID" : "PAY-76T970067E989851JLPLCMKA", "payerID" : "3LSD3Q8J7T3ZL" } The server then remodels the payload for a query to paypal's POST Execute endpoint as follows:
headers:
Content-Type = "application/json" Authorization = "Bearer " + accessToken // checked not expired and a body payload of:
{"payer_id" : "3LSD3Q8J7T3ZL"} The post is then made to:
https://api.sandbox.paypal.com/v1/payments/payment/PAY-76T970067E989851JLPLCMKA/execute
at which point, the paypal server responds with: The remote server returned an error: (400) Bad Request.
Form what I can see, this matches the API requirements outlined here: https://developer.paypal.com/docs/api/payments/v1/#payment_execute
As a side note, I setup an endpoint on my own server to check the headers and JSON payload being submitted to the Paypal execute endpoint are correct.
Any suggestions would be greatly appreciated.
