  ThreatLocker publishes NO AsyncAPI document and no API-level webhook subscription endpoint. It DOES
  ship a real outbound event surface: ThreatLocker Detect policies fire configurable response actions
  when a detection condition is met, and two of those actions post to a customer-supplied HTTP
  endpoint. This is a policy-driven webhook, configured in the portal per Detect policy, not a
  subscription managed through the PortalAPI — so there is no channel catalog or message schema to
  harvest. No AsyncAPI pointer is wired in apis.yml; only `Webhooks`.
surface:
  kind: policy-triggered outbound HTTP
  product: ThreatLocker Detect
  configured_in: ThreatLocker Portal — Detect policy response actions
  docs: https://threatlocker.kb.help/forwarding-information-to-your-siem-using-threatlocker-detect/
  subscription_api: false
  replay: false
  signing: 'not documented — authentication is whatever custom headers or OAuth bearer token the operator configures'
actions:
- name: Call Webhook
  description: Sends data to a predefined URL when the Detect policy condition is met. Dispatched from the ThreatLocker cloud.
  target: operator-supplied URL
- name: Call Webhook (Client)
  description: >-
    The ThreatLocker agent on the endpoint triggers the webhook directly. ThreatLocker recommends the
    Client variants because delivery is faster, straight from the agent.
  target: operator-supplied URL
- name: Call Rest API
  description: Makes an HTTP request (GET/POST/PUT/DELETE/PATCH) to an arbitrary endpoint when the condition is met. Dispatched from the ThreatLocker cloud.
  target: operator-supplied URL
- name: Call Rest API (Client)
  description: Same as Call Rest API, dispatched from the endpoint agent.
  target: operator-supplied URL
delivery:
  http_methods: [GET, POST, PUT, DELETE, PATCH]
  body: >-
    Fully operator-defined. The documented SIEM example uses a body shaped like
    {"event":"", "sourcetype": ""} where `event` carries the logged data and `sourcetype` is
    operator-chosen; ThreatLocker variables are substituted into the body at dispatch time.
  headers: Custom headers supported for authorization tokens; an optional OAuth Bearer token can be configured.
  targets: Any SIEM HTTP Event Collector or HTTP endpoint the operator configures.
event_sources:
  note: >-
    Triggering conditions are authored per Detect policy against ThreatLocker telemetry. The
    documented example fires on a "Deny (Option to Request)" policy action. The equivalent event
    corpus is readable over the PortalAPI via the ActionLog and SystemAudit resources.
