Sent by the server to the client as soon as possible after they connect to the gateway.
JSON data format:
| Field | Description |
| - | - |
| pingInterval | Every *pingInterval*, the client must send a packet simply containing `7@1`. This is the ACTION_PING payload. If the client does not send this payload at the right time, it is disconnected. |
| supportedAttributes | An array of attributes supported by the server. If a client requests an unsupported attribute, it is disconnected from the server. |
This payload contains a `pingInterval` property. Every *pingInterval*, the client must send a packet simply containing `7@1`. This is the ACTION_PING payload. If the client does not send this payload at the right time, it is disconnected.
Example:
```json
0@{"pingInterval":14750,"supportedAttributes":["PRESENCE_UPDATES"]}
0@{"pingInterval":14750}
