HTTP status codes / 2xx — Success
The request succeeded; the response carries the result.
The standard success response. What "success" means depends on the method: a GET returns the resource, a POST returns the result of the action, a PUT/PATCH usually returns the updated representation or confirmation.
curl -i https://httpbin.org/get
Same request, no terminal: paste this into the cURL converter for native code, or straight into ReqPad on your phone.
A 200 with an unexpected body (e.g. an HTML error page from a proxy) is a classic trap — always check the response content, not just the status.
The fastest way to pin down a 200 is to reproduce the exact request and inspect what actually went over the wire — status, headers, timing and body, without your app code in the way. That is what an API client is for; ReqPad does it from your phone, with every request saved to history.
