Usage info
This method pins a message to a particular conversation or channel.
Both the channel
and timestamp
arguments are functionally required. The provided channel
should be the ID of a public or private channel you want to pin to and the timestamp
should be the ts
value of a message within that conversation.
In the past, files and file comments could be pinned to a channel as well.
Response
After processing, a pin_added
event is broadcast via the Events and RTM APIs.
Some objects cannot be pinned: channel join messages, files, and file comments. A not_pinnable
error is thrown when we "no can do."
Typical success response
{
"ok": true
}
Typical error response
{
"error": "channel_not_found",
"ok": false
}
