+If you choose to fetch message information from an endpoint, the output format should be:
+
+```json
+{
+       "style": null,
+       "title": "Lorem ipsum 42",
+       "content": "LA LA LA Lorem ipsum dolor sit amet, ....."
+}
+```
+
+`null` value or missing keys will be ignored and value from the `config.yml` will be used if available.
+Empty values (either in `config.yml` or the endpoint data) will hide the element (ex: set `"title": ""` to hide the title bar)
