Create Request from Code

Paste a code snippet — a cURL command, a Postman-generated C# HttpClient call, a Python requests script, a JavaScript fetch, and more — and Rostyman turns it into a ready-to-send request: method, URL, query parameters, headers, and body. It runs entirely offline using built-in parsers — no AI required.

Opening the dialog​

There are two ways in:

  • Toolbar — click the </> (Create from Code) icon in the request toolbar.
  • Sidebar — right-click a collection or folder → Import from Code.

Paste, detect, preview​

  1. Paste your snippet into the box.
  2. Rostyman auto-detects the language (shown above the preview); override it any time with the language dropdown.
  3. A live preview shows exactly what will be created — method, URL, params, headers, and body — and flags anything it couldn't map.

Import vs Create​

When you confirm, you choose how the parsed request lands:

  • Import — replaces the current request tab with the parsed request. Useful for dropping a snippet into the tab you're already working in; the scripts on that tab are preserved.
  • Create — opens the parsed request in a new tab. (When you started from a collection or folder right-click, it's saved as a new request there instead.)

Supported languages​

17 languages are recognized:

cURLHTTPie
C# HttpClientPowerShell Invoke-WebRequest
Python requestsPython httpx
JavaScript fetchaxios
Node.js fetchPHP cURL
Go net/httpRuby net/http
Java HttpClientKotlin OkHttp
Swift URLSessionDart http
Rust reqwest

Rostyman also generates snippets in these same languages (from a request, via the Code panel) — so you can round-trip: copy a snippet out of any tool, paste it in here, and send it.

What gets parsed​

  • Method and URL — query-string parameters are split out into the Params tab.
  • Headers — including auth headers like Authorization.
  • Request body — raw JSON, text, and XML, plus common form bodies. Multi-line and nested JSON is handled.

Where a snippet contains something Rostyman can't map cleanly, the preview tells you what was skipped, so nothing is silently lost.

Tips​

  • Leading/trailing whitespace and shell line-continuations (\) are handled automatically.
  • If auto-detect picks the wrong language, set it manually — the preview updates instantly.
  • Nothing leaves your machine: parsing is local, with no network or AI call.
