Attio webhook events.

15 events emitted by Attio in the team-ops webhook catalog. Each event below carries the canonical event name, payload schema (field names and types only), auth method, signature header, retry policy, and a link back to Attio's docs.

Auth mix: 15 hmac-sha256 · Source extraction: 2026-10-12

v1 verification gap

Audit gap: docs URLs returned 404/redirect or were too thin to cross-check on 2026-05-13. Plausible but unconfirmed. Planned re-extraction in v1.1.

All 15 events

Direct anchors. Each event header links to its own URL.
