Frequently Asked Questions
A REST Request Builder is a visual developer utility that allows you to construct, inspect, and format HTTP requests (including methods, target URLs, query parameters, custom headers, authentication credentials, and request bodies) without manually writing raw HTTP syntax or complex command line flags.
No. This tool is strictly a request builder and specification generator. It operates 100% client-side inside your browser sandbox and never executes network calls or sends your data to any remote server.
Never. All input credentials (Bearer tokens, Basic Auth credentials, API keys, and OAuth parameters) exist solely in your browser's temporary state memory. Nothing is ever saved to localStorage, cookies, or transmitted over any network.
You can export your completed request specification as raw HTTP/1.1 syntax, executable cURL shell commands, downloadable JSON configuration files, or generate shareable link hashes with embedded parameters.
When credential masking is enabled, Authorization headers and API keys in the live HTTP preview card are automatically obscured (e.g. 'Authorization: Bearer sample_•...'). You can toggle masking on or off at any time.
