See what your payment provider actually sent.

Point a sandbox webhook at a throwaway URL, watch requests land live, and learn which wrong rule your signature code applied — not just that it failed.

• CaptureAny method, any path. Headers and bytes exactly as received.
• VerifyYour passphrase or signing secret lives for one request and is never written down.
• DiagnoseThe trace names the rule your code got wrong.

The verifiers here are the payments kit's own, from its core module, so a trace here is the verdict the kit would reach.
