How to assemble a curl command from URL + method + headers + body

1. URL and method

   "URL" is the full target (with scheme — `https://api.example.com/v1/users`). "Method" is the HTTP verb (GET, POST, PUT, PATCH, DELETE, …). Methods other than GET are emitted with `-X METHOD`.

2. Headers (one per line)

   "Headers (Key: Value per line)" accepts standard `Key: Value` pairs, one per line. Each non-empty trimmed line becomes `-H 'Key: Value'`. Lines without a colon are silently skipped.

3. Body

   "Body" (optional) is the raw request body — JSON, form-urlencoded, or anything you'd POST. Non-empty body becomes `--data '…'` with the body single-quoted (literal single quotes in the body aren't auto-escaped — watch out).

4. Press Run

   Result is a single `command` field — `curl 'URL' [-X METHOD] [-H 'K: V']... [--data '…']`. Paste into a terminal that supports POSIX single-quoting (bash, zsh). For PowerShell or cmd.exe you'll need to re-quote.
