Reach for this tool when debugging webhook payloads, validating headers, formatting JSON, or preparing HTTP snippets before you wire up a tunnel for live provider callbacks. It is especially useful when staging is unavailable or too slow for quick iteration.
Passo a passo no navegador
Exemplos Stripe, GitHub; PT-BR (validador, assinatura, webhook).
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.

Start with realistic webhook or API samples from your provider docs. The webhook verificador assinatura hmac sha256 highlights syntax errors, missing fields, and encoding issues so you can fix problems before events hit your local server.
Erros comuns e correções
Exemplos Stripe, GitHub; PT-BR (validador, assinatura, webhook).
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.
Segurança e privacidade (processamento no cliente)
Exemplos Stripe, GitHub; PT-BR (validador, assinatura, webhook).
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.
