Usage info
Create a public or private channel using this Conversations API method.
Use conversations.open to initiate or resume a direct message or multi-person direct message.
The team_id is only relevant when using an org-level token. This field will be ignored if the API call is sent using a workspace-level token.
Naming
Channel names may only contain lowercase letters, numbers, hyphens, and underscores, and must be 80 characters or less. When calling this method, we recommend storing both the channel's id and name value that returned in the response.
Channel names are always validated by this method.
