About API Tester
Send HTTP requests (GET, POST, PUT, DELETE and more) with custom headers and a JSON body, then inspect the response status, headers and body. It's a lightweight alternative to heavy API clients for quick checks. Requests run from your browser with CORS applied.
Common uses
- Quickly check an API endpoint
- Debug webhook payloads
- Test request/response pairs during development
