### Messaging format
The framework uses JSON messages internally and in exposed APIs as well.
These messages must comply some rules.
Don't worry, we are not too fond of rules around these parts.
The TFW message format:
```json
{
"key: "some identifier used for addressing",
"data":
{
...
JSON object carrying anything, preferably cats
...
},
"trigger": "FSM action"
}
```
- The `key` field is used by TFW for addressing and every message must have one (it can be an empty string though)
- The `data` object can contain anything you might want to send
- The `trigger` key is an optional field that triggers an FSM action with that name from the current state (whatever that might be)
