- 訂閱WISE-IoTSuite/Notification需要先綁定RabbitMQ服務方可使用此功能

1. 建立一個通知群組, 並複製群組ID (groupId)  

2. 從 Management Portal 取得 MQTT連線資訊

```auto
host: {credentials.externalHosts}
port: {credentials.protocols.mqtt.port}
username: {credentials.protocols.mqtt.username}
password: {credentials.protocols.mqtt.password}

```

1. 以MQTTBox工具為例, 發送MQTT訊息

- Topic: /wisepaas/notify/send
- Payload: 與API格式相同

```auto
[{
    "groupId": "i6t2LAIwKrRf",
    "useTemplate": false,
    "message": "for demo"
}]

```
