APIVoid Request Tester

Send HTTP requests to test API endpoints. Save reusable request profiles, set custom headers, and inspect responses.

Send and test HTTP API requests directly from your browser, with full control over headers, body, and method. Five request body formats: • None - for GET, HEAD, and other body-less requests • JSON - pretty input with automatic Content-Type • Form-urlencoded - for classic form submissions • Raw text - send any payload as-is • Custom headers - add, edit, and remove headers freely Save any request as a named profile and re-run it later with a single click. All seven HTTP methods are supported (GET, POST, PUT, DELETE, PATCH, HEAD, OPTIONS). Inspect responses with status code, total time, payload size, full response body (JSON is auto-formatted and syntax-highlighted), and a complete response headers table. Copy or save the body and headers to a file in one click. No uploads, no external servers, no telemetry, everything runs locally in your browser. Saved profiles live only in your local extension storage. Very simple to use: • Click the pinned icon on the toolbar • Enter a URL, pick a method, add headers or a body if needed • Click "Send Request" to see the response • Click "Save Profile" to store it for later • Re-run any saved profile from the "Saved Profiles" tab Built for developers who frequently test API endpoint.
