How do I send a PUT request in Go?

Paste your curl PUT command above. Toolpaper generates Go using net/http with headers, query string, and (where applicable) request body wired up.

Does the PUT generator handle authentication?

Yes — Authorization headers, Bearer tokens, Basic auth (-u), and API keys pass through to the generated Go code unchanged.

Is my curl sent to a server?

No. Parsing and code generation run in your browser. Nothing is uploaded.

Can I also convert this to other languages?

Yes. Once you paste your command, the language picker lets you switch between 18 targets (fetch, axios, Python, Go, PHP, Ruby, Rust, Java, Kotlin, C#, PowerShell, Swift and more).

Convert a cURL PUT request to Go

Paste any curl PUT command and get clean Go code using net/http. Runs entirely in your browser — headers, auth, and JSON bodies map to idiomatic Go.

Quick answer

To convert a cURL command to Go, paste it into the Toolpaper workbench below. It parses the command in your browser and emits idiomatic Go code — headers, query string, request body, authentication (Bearer, Basic, API key), and cookies are all wired up automatically. No data is uploaded; conversion is fully client-side.

Prefer a different target? See the full cURL to Go reference, or jump to the same guide in JavaScript, Node.js, or Python.

Example

A representative curl command for this scenario. Paste your own above to convert an exact match.

curl input

curl -X PUT https://api.example.com/users/42 \
  -H "Content-Type: application/json" \
  -d '{"name":"Ada Lovelace"}'

Implementation notes

Request-line method (PUT) and target URL are extracted from the curl command exactly as written — no case-folding, no path rewriting.
Every -H header maps to a Go header entry; duplicates are preserved so servers that read multi-valued headers keep behaving.
Query strings in the URL stay in the URL; -G with --data-urlencode is promoted to a structured params argument where net/http supports it.
Request bodies are parsed against Content-Type: JSON bodies use idiomatic serialization (net/http), form bodies use URL-encoding, multipart uses -F semantics with file@ handling.
TLS flags (--insecure, --cacert, --cert) surface as inline notes so you don't ship an insecure client to production by accident.

Common mistakes

Forgetting that -X PUT without a body still sends an empty body — the generated code mirrors that exactly.
Assuming curl auto-follows redirects: it doesn't. Add -L (or the generator's follow-redirects flag) if you actually need to chase 3xx responses.
Copying a Cookie header from DevTools that already encodes session state — use the Clean panel to strip session cookies before you share.
