PayPal Sandbox API endpoint returning 503 “Internal Service Error” error

问题

I'm working with the PayPal REST API on the sandbox endpoint at https://api.sandbox.paypal.com/v1/ and nearly every single time I try to POST to payments/payment with a valid request (taking care not to be flagged as a duplicate attempt) it keeps returning a 503 error.

Only very occasionally does the request go through but it only did that earlier and now every request is failing with a 503 response. Even when I use PayPal's REST Playground at https://devtools-paypal.com/hateoas/index.html?interactive=ON&env=sandbox to build their sample template request I get the following response:

Response Header

  ],

}

Response Body

{
  "name": "INTERNAL_SERVICE_ERROR",
  "information_link": "https://api.sandbox.paypal.com/docs/api/#INTERNAL_SERVICE_ERROR",
  "debug_id": "56fbd9db69555"
}

This is so incredibly annoying I can't stand it. Does anyone know if the sandbox site goes down from time to time? Has anyone run into this happening and realized they were doing something wrong in their request? Again, after I ran into the issue I tried submitting to the API using PayPal's very own example template in the REST Playground page.

回答1:

Regarding "INTERNAL_SERVICE_ERROR", in sandbox environment, the testing credit card in your API request is a generic one and there are lots of accounts attached to this credit card, when PayPal execute your API request, we need to load all the related accounts during transaction, so it caused time out error and internal service error, please try some rarely used card number, such as below:

VISA 16 digit
