Debug REST API Requests from cURL Without Leaving the Browser
Import cURL commands, tweak auth and headers, switch around CORS issues, and inspect the live response from one workspace.
Why this workflow matters
Most API debugging gets split across terminal, browser tabs, token tools, and copied payloads. This workflow keeps the request, auth, response, and JSON inspection steps together.
What success looks like
- Replay failing requests faster than rebuilding them from scratch.
- Check headers, auth, and response shape in one place.
- Shorten the loop between request changes and validated responses.

Recommended workflow
- 1
Paste the cURL command into API Explorer or rebuild the request manually with the right method, URL, headers, and body.
- 2
Send it in browser mode when CORS allows it, or switch to proxy mode when the endpoint is blocked.
- 3
Inspect the formatted response, compare runs, or decode bearer tokens when auth is part of the failure.
