I am trying to figure out what the errors endpoint is used for, so I can I can implement it in my API.

I have been trying things like:

And I am getting a File Not Found Error in Firefox.

All the errors help page says is:

Simulates an error given a code

What are valid error codes? And, can we get some sort of response telling us that we supplied a bad error code?

The /errors method was requested to make it easier to test libraries. Finding questions/users/etc. that result in certain error cases can be... trying, and potentially quite brittle.

Defined Error Codes:

Invalid error codes result in a 404 error (NotFound).

Could you please provide me with an example link for a working error call to the api? –  jjnguy Jun 1 '10 at 2:54

Pass the parameter ?type=jsontext to see error JSON



Note: if you don't put ?type=jsontext, error code is simulated only in http response header, so firefox just give you error page.

This is incorrect, the JSON body is always returned. Firefox just doesn't show it to you by default. Either view source, or watch the HTTP traffic in a sniffer to see the error message. –  Kevin Montrose Jun 1 '10 at 6:55
@Kevin, You're right, I've crossed-out that part, my firefox just gave me alert Firefox can't find the file at http://api.stackoverflow.com/0.8/errors/4005., view-source was not viewable, so I assumed it was only in http headers. didn't watch with HTTP traffic, I stand corrected. –  YOU Jun 1 '10 at 7:24
