OK

The request succeeded. The meaning depends on the method used.

200 OK is the standard response for a successful HTTP request. What 'success' means depends on the method: a GET returns the resource, a POST returns the result of the action, and so on. If you're debugging an API and seeing 200 when you expected an error, check the response body - some services return a 200 with an error payload inside instead of a proper 4xx or 5xx code.
