Toolpaper

Convert a cURL DELETE request to Kotlin

Paste any curl DELETE command and get clean Kotlin code using OkHttp. Runs entirely in your browser — headers, auth, and JSON bodies map to idiomatic Kotlin.

Quick answer

To convert a cURL command to Kotlin, paste it into the Toolpaper workbench below. It parses the command in your browser and emits idiomatic Kotlin 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 Kotlin 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 DELETE https://api.example.com/users/42 \
  -H "Authorization: Bearer YOUR_TOKEN"

Implementation notes

  • Request-line method (DELETE) and target URL are extracted from the curl command exactly as written — no case-folding, no path rewriting.
  • Every -H header maps to a Kotlin 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 OkHttp supports it.
  • DELETE with a body (some REST APIs require it) is preserved — many generators mistakenly strip it, Kotlin keeps the payload attached.
  • 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 DELETE 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.

Common questions

How do I send a DELETE request in Kotlin?
Paste your curl DELETE command above. Toolpaper generates Kotlin using OkHttp with headers, query string, and (where applicable) request body wired up.
Does the DELETE generator handle authentication?
Yes — Authorization headers, Bearer tokens, Basic auth (-u), and API keys pass through to the generated Kotlin 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).
