Continuous Monitoring webhooks

For a minimal integration, subscribe to monitoring.delta.detected. Add monitoring.run.failed when your operations team must react to an incomplete check. Do not subscribe to high-volume monitoring.run.completed unless your system needs every successful run.

Events

Event	When it fires
`monitoring.subscription.started`	Monitoring becomes active for an Entity.
`monitoring.subscription.paused`	Scheduled monitoring is paused.
`monitoring.subscription.resumed`	A paused subscription becomes active.
`monitoring.subscription.ended`	A subscription is permanently turned off.
`monitoring.subscription.updated`	An Entity's policy or frequency changes.
`monitoring.run.completed`	One monitoring run completed.
`monitoring.run.failed`	One monitoring run could not complete.
`monitoring.delta.detected`	Monitoring found one or more material changes.

monitoring.failed is not a public event name.

Public data contract

Field	Events	Meaning
`subscriptionId`	All	Customer-addressable monitoring subscription.
`entityId`, `externalUserId`, `subject`	Entity-related events	Customer correlation without internal source data.
`status`	Subscription lifecycle	`active`, `paused` or `ended`.
`frequency`	Subscription updated	Effective frequency, policy default, Entity override and source.
`materialChange`, `completedAt`	Run completed	Whether the successful run found a material change and when it completed.
`failureCode`, `failedAt`	Run failed	Stable failure classification and time.
`deltas`, `detectedAt`	Delta detected	Customer-visible material changes and detection time.

Internal policyVersionId, monitoringRunId and assessmentId fields are not included. Read current state and history from GET /api/v1/monitoring/subscriptions/{subscriptionId}.

Verify the raw request body, deduplicate by envelope id, return 2xx quickly, and use the read API whenever current state matters.
