What Is HTTP Request Builder?
HTTP Request Builder is a visual tool for constructing HTTP requests and instantly generating ready-to-use code snippets in curl, JavaScript fetch, and axios. Configure the method, URL, headers, query parameters, request body, and authentication — then copy the generated code directly into your project.
How to Use
- Select an HTTP method (GET, POST, PUT, PATCH, DELETE, etc.)
- Enter the request URL
- Add query parameters, headers, or a request body as needed
- Configure authentication (Bearer token, Basic auth, or API key)
- Switch between curl, fetch, and axios tabs to see the generated code
- Click Copy to copy the snippet to your clipboard
Features
- Supports GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS methods
- Query parameter builder with enable/disable toggles
- Custom header editor with per-row toggles
- Request body: JSON, form-encoded, or plain text
- Auth: Bearer token, HTTP Basic, or custom API key header
- Generates curl, fetch, and axios code in real time
FAQ
Does this tool send the actual request?
No. This is a code generator only — it builds the snippet but does not execute the request. Use the generated code in your terminal or application.
How is Basic auth encoded?
The username and password are combined as username:password and Base64-encoded, then sent as the Authorization: Basic ... header — the standard HTTP Basic authentication scheme.
Can I use this for REST API testing?
Yes. Build your request visually, copy the curl command, and run it in your terminal. It is also useful for generating boilerplate fetch/axios code to paste into your codebase.
Are my credentials stored anywhere?
No. Everything runs in your browser. No data is sent to any server.
