Data
API Tester
Test HTTP APIs with headers, body and params. Send GET, POST, PUT, PATCH, DELETE requests and view responses.
How it works
A powerful HTTP API testing tool that lets you send requests to any REST endpoint and analyze the response.
Supports all common HTTP methods including GET, POST, PUT, PATCH, and DELETE. Add custom headers as key-value pairs, send JSON body with POST and PUT requests, and append query parameters to your URLs.
The response panel displays status code with color coding (green for 2xx, amber for 3xx, red for 4xx/5xx), response time in milliseconds, and all response headers. JSON responses are automatically formatted for easy reading.
Perfect for developers testing APIs, debugging webhook integrations, or checking endpoint responses. No signup required - use it directly from your browser.
