description: >-
  Harbor's event surface is a per-project webhook policy: a project administrator registers
  an endpoint and Harbor POSTs a JSON notification when one of ten documented events occurs
  in that project. There is no AsyncAPI document and no streaming/queue surface — Harbor
  publishes NO AsyncAPI specification, and none is authored here. What follows is the
  published event catalog, the two payload formats, and the API operations that manage
  subscriptions.
asyncapi_published: false
delivery:
  transport: HTTP(S) POST
  endpoint_kinds:
  - http
  - slack
  scope: per project — multiple endpoints may be registered per project
  payload_formats:
  - name: Default
    note: Harbor's original payload shape, unchanged across versions. Fields — type, occur_at, operator, event_data{resources[], repository{}}.
  - name: CloudEvents
    note: 'Same data wrapped per CloudEvents 1.0 — specversion, id, requestid, source (/projects/{id}/webhook/policies/{policy_id}), type (e.g. harbor.artifact.pushed), datacontenttype, time, data.'
    spec: https://cloudevents.io
  retries: not published
  signing: not published
  note: The docs describe no signature header and no retry/backoff policy for webhook delivery.

    method: POST /projects/{project_name_or_id}/webhook/policies
    purpose: Register an endpoint and select the events and payload format.
  - operationId: ListWebhookPoliciesOfProject
