$connect

The $connect route is invoked when a client first connects to the WebSocket API. This is where authentication and authorization occur. The connection is established only if the integration returns a successful response. Query string parameters and headers from the initial HTTP upgrade request are available to the integration.

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.
