  note: >-
    No AsyncAPI document is published. The event surface is real and documented in prose, so it is
    captured here as a webhook catalog. Nothing below is generated — every event name and every
    delivery rule is copied from the provider's own docs.
description: >-
  One has TWO distinct event surfaces and they should not be confused. (1) Platform webhooks —
  subscriptions to events inside your One account, catalogued below. (2) Relay — inbound webhooks
  from 80+ third-party platforms, normalised and forwarded; that is an ingress product, not an
  outbound event catalogue, and its event types are the upstream platform's own
  (list_webhook_relay_event_types enumerates them per connector at runtime).
webhooks:
  transport: HTTPS POST to a subscriber-supplied endpoint
  management: https://app.withone.ai/webhooks (dashboard) and the Webhook Subscriptions API
  signature:
    header: X-Webhook-Signature
    mechanism: >-
      Signed when a secret is supplied at subscription creation. The upsert schema notes the delivery
      path "only signs when a subscription has one, so a secretless listener would receive bodies a
      client cannot verify" — which makes the secret effectively mandatory in practice.

  payload_note: >-
    The docs name the events but publish no payload schema for any of them, and the OpenAPI declares
    no `webhooks:` block (OpenAPI 3.1 supports one; this spec's is empty). A consumer cannot generate
    a typed listener from anything One publishes.
