Keep receiving 404 Error with Rest API when doing a capture - paypal

Question

This is an edit to my original post. I think the paypal rest api sandbox is down.
The error just started and I haven't had it before:
here is the capture URL:
https://api.sandbox.paypal.com/v1/payments/payment/PAY-8EN83459YH6921921KJ4QNHQ
Its a 404 error. Here is the body:
{
name: "INVALID_RESOURCE_ID"
message: "The requested resource ID was not found"
information_link: "https://developer.paypal.com/webapps/developer/docs/api/#INVALID_RESOURCE_ID"
debug_id: "e56bae98dcc26"
}
The payment was properly created and I used the same credentials and the payment link provided in the returned payment creation response.
Here was the response from the original payment creation call:

Answer 1

There is a reported problem at the moment with REST API. PayPal are working on it.

Answer 2

I was hitting my head against the wall for a while thinking that this PayPal bug was the cause of my problems. However, it turns out that PayPal generates the same error when you are using the wrong configuration in your client. In my case, I had the Android library set to use ENVIRONMENT_NO_NETWORK, and not ENVIRONMENT_SANDBOX. This produces real-looking transaction IDs, which (of course) are not registered with the server.
