  openapi/_original/oracle-cloud-notifications-openapi.yaml
provider: Oracle Cloud Infrastructure
providerId: oracle-cloud
asyncapi_published: false
asyncapi_note: >-
  Oracle publishes NO AsyncAPI document for OCI Events, Notifications, Streaming or Queue. The
  event surface is real and well documented, but its contract is expressed as CloudEvents envelopes
  plus per-service event-type reference pages, and its control plane is REST (Swagger 2.0). Nothing
  is fabricated here — this file is the webhook/event catalog, not a synthesized AsyncAPI.
event_surface:
  service: OCI Events
  control_plane_spec: openapi/_original/oracle-cloud-events-openapi.yaml
  control_plane_operations: [ListRules, CreateRule, GetRule, UpdateRule, DeleteRule, ChangeRuleCompartment]
  model: >-
    OCI services emit events onto a tenancy-wide bus. A Rule matches events by a filter over
    eventType / compartment / tags and routes matches to one or more Actions: a Notifications topic,
    a Streaming stream, or a Function.
  envelope:
    standard: CloudEvents
    version: '0.1'
    hosted_by: Cloud Native Computing Foundation
    docs: https://docs.oracle.com/en-us/iaas/Content/Events/Reference/eventenvelopereference.htm
    statement: >-
      Verbatim from Oracle: "The structure of the envelope follows the CloudEvents industry
      standard format hosted by the Cloud Native Computing Foundation (CNCF)." and "Events uses
      version 0.1 specification of the CloudEvents event envelope."
    fields:
      - {name: cloudEventsVersion, example: '0.1'}
      - {name: eventID, description: Unique event identifier.}
      - {name: eventType, example: com.oraclecloud.objectstorage.deletebucket}
      - {name: eventTypeVersion, example: '1.0'}
      - {name: source, example: objectstorage}
      - {name: eventTime, example: '2019-01-10T21:19:24Z'}
      - {name: contentType, example: application/json}
      - {name: extensions, description: 'Mandatory in Oracle''s implementation; carries compartmentId and tenancy context.'}
      - {name: data, description: Service-specific payload including resourceId and additionalDetails.}
    deviation: >-
      CloudEvents 0.1 predates the 1.0 attribute names. OCI uses cloudEventsVersion / eventID /
      eventTime rather than specversion / id / time, and adds a mandatory `extensions` object. A
      consumer written against CloudEvents 1.0 will not parse an OCI event without a shim.

webhooks:
  supported: true
  mechanism: OCI Notifications subscription with the HTTPS (Custom URL) protocol
  control_plane_spec: openapi/_original/oracle-cloud-notifications-openapi.yaml
  control_plane_operations: [CreateSubscription, ListSubscriptions, GetSubscription, UpdateSubscription, DeleteSubscription, GetConfirmSubscription, ResendSubscriptionConfirmation, GetUnsubscription, PublishMessage]
  endpoint_field:
    name: endpoint
    max_length: 512
    description: >-
      Verbatim from the Notifications contract: "A locator that corresponds to the subscription
      protocol... HTTP-based protocols use URL endpoints that begin with 'http:' or 'https:'. A URL
      cannot exceed 512 characters."
  confirmation:
    required: true
    operations: [GetConfirmSubscription, ResendSubscriptionConfirmation]
    note: >-
      A new subscription is created in PENDING state and must be confirmed via the confirmation URL
      Oracle delivers to the endpoint before messages flow. Unsubscribe is a matching
      GetUnsubscription call.
  protocols:
    - {name: EMAIL, kind: email}
    - {name: HTTPS (Custom URL), kind: webhook}
    - {name: Function, kind: compute}
    - {name: PagerDuty, kind: integration}
    - {name: Slack, kind: integration}
    - {name: SMS, kind: sms}
  delivery_guarantees_documented: false
  delivery_note: >-
    Retry policy, delivery timeout and signature verification for HTTPS subscriptions are not
    stated on the pages fetched in this pass, so nothing is asserted about them here.
alternative_streams:
  - {service: OCI Streaming, kind: kafka-compatible, spec: not harvested in this pass}
  - {service: OCI Queue, kind: message-queue, spec: not harvested in this pass}
