The provisioning WebSocket channel used during the device linking flow. A new device connects to this channel and receives a provisioning UUID. The primary device then sends an encrypted provisioning message containing the account identity key and other credentials needed to complete the linking process.

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.

Browse every event-driven channel on the APIs.io network or compare with the broader Agent Skill and MCP server surfaces of the same providers.
