I finished my PayPal REST API integration yesterday for executing simple payments through my website. My script does the following things:
- gets a bearer token
- creates a payment (allowing paypal as the only payment method)
- sends to user to PayPal for authorisation
- executes the payment
This was all working perfectly in the Sandbox yesterday.
Today I tried it (still in the Sandbox) and the execute command is returning an "INTERNAL_SERVICE_ERROR" message. The debug_id from my most recent attempt was 93a4116223d6e.
What is particularly strange is that the payment has been processed correctly. When I log in to the sandbox accounts for the buyer and seller the transaction shows up there as usual.
Any idea why I am suddenly getting these error messages?
