 `payload` must be a string. If you want to send JSON then you need to format/escape it properly. Like:
 
-```json
-{
-  "topic": "home-assistant/light/1/state",
-  "payload":"{\"Status\":\"off\", \"Data\":\"something\"}"
-}
+```yaml
+topic: home-assistant/light/1/state
+payload: "{\"Status\":\"off\", \"Data\":\"something\"}"
 ``` 
 
 Example of how to use `qos` and `retain`:
 
-```json
-{
-  "topic": "home-assistant/light/1/command",
-  "payload": "on",
-  "qos": 2,
-  "retain": true
-}
+```yaml
+topic: home-assistant/light/1/command
+payload: on
+qos: 2
+retain: true
 ```
