# Webhook Automation Webhooks provide push delivery for runtime events and lifecycle updates. ## Delivery Notes - Generic webhooks receive signed JSON and should validate x-cosantoir-signature on every request. - Slack incoming webhooks use Slack message payloads instead of the generic signed JSON envelope. - PagerDuty Events v2 destinations require the official /v2/enqueue endpoint plus a routing key instead of a Cosantoir signing secret. - Return 2xx quickly and process asynchronously. - Configure replay handling with idempotency keys. ## Troubleshooting Use delivery logs and replay endpoints for failed events.
