About the Webhook Request Inspector

Paste a raw HTTP request captured from a webhook to see its parsed method, path, headers, and pretty-printed JSON body. Signature headers like X-Hub-Signature and Stripe-Signature are highlighted, with a built-in HMAC-SHA256 verification box. This tool does not receive live traffic — it only inspects requests you paste in.
