spec_type: Webhooks
notes: >-
  Form3 delivers asynchronous processing results and lifecycle events through Event
  Notifications. A consumer creates a subscription describing which record types/events to
  receive and a destination; Form3 then POSTs signed notifications to that destination.
  Form3 does not publish an AsyncAPI document, so this captures the webhook surface derived
  from the Event Notifications API operations and tutorials.
delivery:
  transport: https-webhook
  signing: >-
    Notifications are signed and must be verified by the consumer (see the "verify event
    notifications" tutorial) using the HTTP Message Signatures scheme.
  format: application/vnd.api+json (json:api envelope)

    and their status changes.
