app/messages
Custom application messages broadcast between clients. Clients publish with `useBroadcastWebsocketMessage` (setting a `target`) and subscribe with `useOnWebsocketMessage`. A trusted server broadcasts the same message shape with `whopApi.websockets.sendMessage`.

application/jsonAbout 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.
