  openapi/social-fetch-openapi.json (/v1/monitors, /v1/webhook-endpoints,
  /v1/webhook-deliveries), docs/monitors/quickstart.mdx, and the live MCP tool
  descriptions for monitors_* / webhookEndpoints_* (read 2026-09-11).
type: Webhooks
asyncapi_spec: null
detail: >-
  Social Fetch ships an event/webhook surface via "Monitors": you watch a social
  account or search, and when a new item appears the monitor delivers a SIGNED
  webhook to a configured endpoint. Baseline checks establish what already exists
  (those do not fire), so only subsequent discoveries deliver events. There is no
  published AsyncAPI document — the event surface is described by REST management
  routes and prose docs.
delivery:
  semantics: at-least-once
  deduplication: event id (consumer-side dedup)
  signing: true
  signing_detail: >-
    Deliveries are signed; the docs state a delivery can be verified "the same way
    as in production". Signing secret is rotated via
    POST /v1/webhook-endpoints/{id}/rotate-secret with a 24h overlap window.
    Exact signature header name not enumerated in the docs excerpt.
  retries: automatic with manual redelivery via POST /v1/webhook-deliveries/{id}/redeliver

notes: >-
  Events are also available by pull (GET /v1/monitors/{id}/events), so the webhook
  is a push convenience over a queryable event log rather than the only path. No
  streaming firehose. AsyncAPI: N/A (none published) — not fabricated.
