Sends a message to a channel. Channel may be specified via ID or username. Messages are markdown-enabled. Users may only send messages to channels for which they are the owner or an administrator.
|
|||
|
|
|
|||
|
|
The following markdown syntax is supported:
|
|||
|
|
*bold text*
|
|||
|
|
_italic text_
|
|||
|
|
[text](URL)
|
|||
|
|
`inline fixed-width code`
|
|||
|
|
```pre-formatted fixed-width code block```
|
|||
|
|
|
|||
|
|
Due to the frequent dysfunction and incompletion of the API method used to determine the administrators of a channel, this command may not work for the owners of some channels.
