What do rate limit errors from the API look like?

[dhughes]

I'm trying to write a test for my application that mimics being rate limited by the weather.gov API. The documentation is a bit vague on what to expect. So, what's actually in a rate limit error? Does it have a 429 status? I've seen things that suggest that it might be a 403 error. Are there any headers telling us how long to back off? Is there anything predictable in the body of the response?

Any info will help. Thanks!

Expect 403 response status error with a Reference ID # in the body.
