  Census (Fivetran Activations) publishes no AsyncAPI document for this surface. This file is the
  webhook catalogue captured verbatim from the published Sync Lifecycle Webhooks page; it is NOT an
  AsyncAPI document and no AsyncAPI pointer is emitted in apis.yml.
name: Census Sync Lifecycle Webhooks
description: >-
  Outbound webhooks that notify an external system about the lifecycle of an Activations sync run and
  about sync alerts. Webhooks are configured per workspace (Workspace settings -> Webhooks tab) and
  are also manageable through the Management API workspace webhooks endpoints.
transport: HTTPS POST to a subscriber-provided endpoint
management:
  ui: Workspace settings -> Webhooks tab -> Add Webhook
  api_resource: Workspace APIs -> webhooks (list, create, fetch, update, delete)
