About the cURL Generator
curl is the lingua franca of API debugging — every API doc, bug report, and incident channel eventually contains a curl command. This builder assembles correct commands from structured inputs: method, URL, headers, body, and auth, so you get proper quoting and flag usage without memorizing syntax.
It is particularly useful for translating a request you can describe ("POST this JSON with a bearer token") into a command you can paste into a terminal, a CI script, or a runbook — with the right -H, -d, and --data-raw flags every time.
Frequently asked questions
What is the difference between -d and --data-raw?
-d (--data) interprets a leading @ as "read from file", which silently breaks payloads that legitimately start with @. --data-raw sends the string exactly as given. For JSON bodies built by hand, --data-raw is the safer habit. Both default the request to POST with Content-Type: application/x-www-form-urlencoded unless you override it.
Why does my curl POST send the wrong Content-Type?
curl defaults to application/x-www-form-urlencoded for -d payloads. APIs expecting JSON will reject or misparse the body unless you add -H "Content-Type: application/json" explicitly. This is the single most common curl mistake in API debugging.
How do I debug what curl actually sent?
Add -v to see the full request and response including headers and TLS negotiation, or -i to include response headers in output. For redirect-heavy APIs, -L follows redirects and -v shows each hop — useful when a 301 silently converts your POST to a GET.
