Fathom Webhooks & Events

Prerequisites

• A verified callback endpoint, signature/authentication rule, idempotency store, redaction policy, and event owner.

Instructions

1. Validate signatures before parsing payloads and acknowledge within the documented timeout.
2. Deduplicate events using stable opaque IDs and record only necessary redacted metadata.
3. Apply bounded retry/backoff for transient errors and quarantine malformed terminal failures.

Output

• A signed, idempotent webhook/event flow with redacted observability, recovery ownership, and a safe replay decision path.
