What is an API Tester?
An API Tester is a tool that allows developers to interact with APIs by sending HTTP requests and inspecting the responses. It's an essential utility for developing, debugging, and learning about APIs without writing any code.
How to Use This Tool
Simply enter the API endpoint URL, select the HTTP method (GET, POST, etc.), and add a JSON body if required. Click 'Send Request,' and the response status, headers, and body will be displayed in the response panel.
Features
- Supports all major HTTP methods: GET, POST, PUT, PATCH, and DELETE.
- View formatted JSON responses and raw response bodies.
- Inspect response headers easily in a separate tab.
- No installation required - everything runs in your browser.
Frequently Asked Questions

Currently, this tool supports sending a JSON body but does not have a feature for adding custom headers like 'Authorization'. This is a planned feature for a future update.
Yes. This API tester is a client-side tool, meaning all requests are made directly from your browser to the API endpoint. No request data is ever sent to our servers.
