List delivery webhooks

We POST to you. This is the surface for an application that has no process to keep running — a Cloud Function, a Lambda, anything that wakes on a request. GET /v1/events needs a held connection; a flow answers for you but cannot consult your own model. This does neither: it hands the event to your endpoint and lets you decide.

Not to be confused with PUT /v1/agents/{id}/webhook, which points Google at a URL instead of at Cadence and switches off flow handling entirely.
