A single partner endpoint receives every subscribed event type. Alto sends one HTTP POST per notification with Content-Type application/json. The partner routes on the CloudEvents `type` field and, where one endpoint serves several integrations, on data.integrationId.
Alto POSTs a CloudEvents 1.0 notification to the partner endpoint.

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.
