cURL Command Builder & Code Exporter

Interactive HTTP request builder and code generator. Configure HTTP methods, endpoint URLs, headers, query parameters, Bearer & Basic Authentication, and JSON/Form request payloads. Automatically exports matching cURL commands alongside native code snippets for JavaScript fetch(), Axios, Python requests, Go net/http, and Node.js.

Preset:

HTTP Request Headers

curl -X POST "https://api.example.com/v1/users?version=2026" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -H "Authorization: Bearer your_secret_api_token_here" \
  -d "{
  \"name\": \"Jane Doe\",
  \"email\": \"jane@example.com\",
  \"role\": \"administrator\"
}"

How to use

  1. Select the HTTP Request Method (GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS).
  2. Enter the target API Endpoint URL (e.g., https://api.example.com/v1/users).
  3. Configure HTTP Request Headers, Query Parameters, and Authentication credentials (Bearer Token or Basic Auth).
  4. Input your JSON or Form Data request body if applicable.
  5. Copy the generated cURL CLI command or switch target language to export JavaScript fetch(), axios, Python requests, or Go code.

Understanding the output

The builder formats standard cURL CLI flags (-X method, -H header, -d body, -u auth) and translates your HTTP request structure into native code snippets for popular backend and frontend programming languages.

Common issues & tips

  • Ensure your API endpoint URL includes the protocol (https:// or http://).
  • When sending JSON request bodies, ensure your JSON string is valid and that the Content-Type header is set to application/json.
  • For APIs requiring CORS authorization in browser environments, verify that your API server emits Access-Control-Allow-Origin headers.

Frequently asked questions

Which programming languages and libraries are supported for export?
The tool exports cURL CLI commands, JavaScript fetch(), Axios, Python requests, Go net/http, and Node.js native fetch.
Is my API key or password sent to any server?
No. Code generation happens 100% locally in your browser. Tokens and request credentials never leave your machine.
How do I add Bearer token authentication?
Switch to the Authentication tab, select 'Bearer Token', and enter your API token. The tool automatically constructs the 'Authorization: Bearer <token>' header across all code exporters.
