sync run. The payload's `action` field identifies whether the call is
a full membership load (`members`), an incremental add
(`add_members`), or an incremental removal (`remove_members`).
Full membership snapshot of a cohort, sent on first sync and on refresh.

About AsyncAPI
The AsyncAPI specification describes event-driven APIs the way OpenAPI describes request/response APIs. A channel is the named pipe — a webhook URL, a Kafka topic, a WebSocket route, an MQTT subject — that producers and consumers publish or subscribe to. Each channel carries one or more messages with structured payloads, and an operation declares whether a given party sends or receives on that channel.
