Verify a webhook signature
Paste a HelloHop delivery's raw body, its signature header, and your signing secret. The page recomputes the HMAC-SHA256 and compares it with the signature you pasted.
Paste the body exactly as your endpoint received it. Do not pretty-print or re-indent it. One changed space or line ending gives a different signature.
What you paste is checked in your browser and is not sent to HelloHop or anyone else. The secret is dropped when you leave or reload this page.
