# `message:get_meta(KEY)`
|
|
|
|
Messages are associated with some metadata. You can think of this metadata
|
|
as being equivalent to a JSON object.
|
|
|
|
The `get_meta` method allows you to retrieve a field of that object.
|
|
|
|
```lua
|
|
msg:set_meta('foo', 'bar')
|
|
print(msg:get_meta 'foo') -- prints 'bar'
|
|
```
|
|
|
|
