API Request Builder

What Is an API Request Builder?

An API request builder lets you construct and send HTTP requests to test REST, GraphQL, or any HTTP-based API directly from your browser. Unlike the cURL Builder which generates curl commands, this tool actually sends the request through our server and displays the live response — including status code, response headers, body content, and timing information.

This is ideal for quickly testing API endpoints during development, debugging webhooks, verifying authentication, inspecting response formats, and troubleshooting integration issues — all without leaving your browser or installing any software.

How to Use

1. Select the HTTP method — Choose from GET, POST, PUT, PATCH, DELETE, HEAD, or OPTIONS.
2. Enter the URL — Paste the full API endpoint URL including the protocol (https://).
3. Add query parameters — Key-value pairs appended to the URL for filtering and pagination.
4. Set headers — Add custom headers like Accept, Authorization, or custom API keys.
5. Provide a body — For POST, PUT, and PATCH methods, enter the request body and select the Content-Type.
6. Configure authentication — Choose Basic Auth or Bearer Token for protected endpoints.
7. Click Send Request — The request is proxied through our server and the full response is displayed.
