type: Webhooks
spec_type: none
notes: >-
  Upsun publishes no AsyncAPI document; this captures the documented webhook
  (activity) event surface. A webhook integration POSTs the full activity
  payload for every activity triggered on a project, filterable by activity
  type and branch.
setup:
  create: upsun integration:add --type=webhook --url=<URL_TO_RECEIVE_JSON>
  update_secret: upsun integration:update <INTEGRATION_ID> --shared-key=<SECRET_KEY>
  validate: upsun integration:validate
delivery:
  method: POST
  payload: full project activity state as JSON (same payload as activity scripts)
  filtering: by activity type and by environment/branch
security:
  signing: >-
    Optional shared key enables an X-JWS-Signature header carrying a JWS
    (RFC 7515) with detached, unencoded payload per RFC 7797; algorithm HS256
    (HMAC-SHA256), protected header {"alg":"HS256","b64":false,"crit":["b64"]}.
    Receivers verify the HS256 MAC over the raw request body bytes.
  header: X-JWS-Signature
