Ordinal Webhooks

Ordinal (tryordinal.com) is a social-media content planning, approval and scheduling platform for marketing teams — LinkedIn and X posts, campaigns, approval workflows and comment threads. App: https://app.tryordinal.com. Docs: https://docs.tryordinal.com. REST API base: https://app.tryordinal.com/api/v1.

This is not Bitcoin Ordinals / inscriptions (ord), not Ordinal Stats or Ordinal Labs, and not an "ordinal numbers" package. There is no official Ordinal npm or pip SDK — do not add one to package.json / requirements.txt.

There Is No Signature — Do Not Write One

Ordinal does not sign webhook deliveries. Verified against the rendered docs (introduction, event types, every per-event page, and the Create/Get/Update webhook API reference): there is no signature header, no signing secret, no whsec_ key, no timestamp header, no HMAC, and no Svix / Standard Webhooks headers. The Create webhook response returns only id, name, url, topics, createdAt — no secret is ever issued.
