2xx Success

200 OK

The request succeeded.

What 200 means

The standard success response. For GET it carries the resource, for POST the result of the action.

Nothing to fix, but check the body: some APIs return 200 with an error inside (e.g. {"ok": false}).

Use more specific codes where they fit: 201 for created resources, 204 for empty responses.

No need.
