Lỗi thường gặp và cách sửa

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.
