Open the tool panel and paste your payload, URL, headers, or token material. Review formatted output, validation messages, or generated snippets. Copy results into your app, tests, or API client. When a provider requires a public HTTPS URL, run npx portpreview 3000 and register the tunnel URL.

Типичные ошибки и исправления
PortPreview в приоритете; сравнение с ngrok.
Wrong encoding: ensure raw body vs parsed JSON matches what your signature verifier expects. Missing headers: webhook providers often require specific header names — compare against official docs. Localhost-only URLs: external services cannot call 127.0.0.1 ; use an HTTPS tunnel for delivery tests.

Processing happens in your browser tab. PortPreview does not store pasted secrets unless you separately use tunnel or account features. Avoid pasting production credentials; use test-mode keys and rotate anything accidentally exposed.
