description: HelixML outbound webhooks send signed, durable notifications when Helix creates a spec task, changes a task status, or publishes
an artifact.
events:
- event: spec_task.created
description: Sent when a spec task becomes available in a project.
- event: spec_task.status_changed
description: Sent when a spec task moves to another status.
- event: artifact.published
description: Sent when Helix creates an artifact or publishes a new version.
delivery:
signature: Standard Webhooks signatures included in the `webhook-signature` header; verify using the `whsec_...` secret.
retries: Automatic retries use exponential backoff with jitter, defaulting to eight attempts over several days; a 2xx response marks success,
410 disables the endpoint, and a valid `Retry-After` header can postpone the next attempt.
note: Each delivery includes `webhook-id`, `webhook-timestamp`, `webhook-signature`, and `webhook-type` headers for verification.
