Online API Testing Tool

Application Programming Interfaces, or APIs, enable software components to exchange data over HTTP. An online testing tool emulates a client, allowing you to craft and send requests manually. Understanding request methods, headers, and bodies clarifies how services respond. Clear definitions prepare you to inspect responses confidently and diagnose integration issues.

This tool’s purpose is to streamline exploration of any endpoint without writing code. You define URLs, choose methods, and adjust query parameters within seconds. Real-time feedback highlights status codes, headers, and body content. Interactive tabs organise parameters, headers, body, and authentication. Comprehensive insight accelerates development cycles and simplifies troubleshooting tasks.

Practical value emerges when you share formatted requests with teammates, replicate reported bugs, or log performance benchmarks. Built-in saving stores configurations for later reuse. Clipboard functions copy responses into documentation instantly. Since processing occurs locally in your browser, no sensitive tokens leave your device. The card layout remains readable on mobile screens.
