HTTP Request Builder

Compose a request — method, URL, query parameters, headers, auth and body — and get copy-ready code for seven languages. This tool only generates code: it never sends a network request.

→ https://api.example.com/v1/users?page=1&limit=25

Query parameters
Headers
Authentication
Body
Variables (use {{name}})
curl -X POST 'https://api.example.com/v1/users?page=1&limit=25' \
  -H 'Authorization: Bearer eyJhbGciOi...' \
  -H 'Accept: application/json' \
  -H 'Content-Type: application/json' \
  --data-raw '{
  "name": "Ada Lovelace",
  "role": "engineer"
}'

Environment / collection export

Exports the variables, request, auth and body as a portable JSON document you can keep in version control or import into another tool.

About this tool

Build an HTTP request and translate it into cURL, fetch, Axios, Python, Go, PHP or PowerShell code. URL templates such as {{baseUrl}} are substituted from the variable table, query parameters are URL-encoded, and the JSON body is validated and can be formatted. Everything runs in your browser — no request is ever sent anywhere.
