Should parameters go in the URL or the body?
Use the URL for routing and query semantics, and use the body for structured payloads such as JSON or form submissions.

About this tool
HTTP Request Builder helps you assemble API requests from structured fields instead of hand-writing commands. You can set method, URL, headers, query parameters, and payload, then generate ready-to-run cURL and fetch snippets in one click. This reduces command syntax mistakes during backend integration, incident debugging, and QA reproduction. It is especially useful when teammates use different tools but need the same request blueprint. Everything runs locally in your browser without sending request content to any server.

Can this help build a reproducible bug report?
Yes. A complete request block with method, URL, headers, and body is often the fastest path to a reliable reproduction.
