description: 'CrowdStrike has a real event surface and publishes NO AsyncAPI for it. The Falcon Event Streams API
  is a PULL-shaped streaming feed: the consumer discovers available streams over REST, then holds open a long-lived
  connection to the returned datafeed URL and refreshes the session periodically. CrowdStrike does not publish an
  outbound webhook catalog on its developer surface, so no Webhooks pointer is emitted for this provider — the event
  surface is subscribe-and-stream, not callback-and-deliver.'
surfaces:
- name: Falcon Event Streams
  transport: long-lived HTTP stream (datafeed URL)
  direction: provider-to-consumer, consumer-initiated
  discovery:
    operationId: listAvailableStreamsOAuth2
    method: GET
    path: /sensors/entities/datafeed/v2
    params:
    - name: appId
      note: consumer connection label, max 32 alphanumeric characters
    - name: format
      values:
      - json
      - flatjson
    scope: 'Event streams: READ'
  session:
    operationId: refreshActiveStreamSession
    method: POST
    path: /sensors/entities/datafeed-actions/v1/{partition}
    scope: 'Event streams: READ'
  content: detections, audit events and platform notifications as they happen
  tooling: CrowdStrike publishes an Event Driven Ansible rulebook source plugin for this stream
- name: Falcon Data Replicator (FDR)
  transport: bulk export to cloud storage
  direction: batch
  collection: FDR
  operations: 5
  note: Bulk telemetry replication rather than an event feed.
- name: Next-Gen SIEM / LogScale ingest
  transport: query + ingest
  note: CQL search over ingested events; parsers must follow the CrowdStrike Parsing Standard (ECS-mapped).
