​
Delete

RoleDelete Scope

Deleting a message also removes all its reactions. Deleting a parent message keeps thread replies intact.

​
Channel Member Management

Channel access is controlled by the access_control field, with read and write permissions configurable independently.
VisibilityDescription
Public (null)All authenticated users can join
Group-restrictedOnly specified group members can join
Organization-restrictedOnly specified organizational unit members can join
Each group/organization can be granted read-only or read+write permission. For example, you can allow only read for one group and read+write for another.
When visibility is null (unset), all authenticated users can read and write in the channel. To restrict, the admin must set visibility explicitly.

​
Notifications

Webhook notifications are sent to users not currently in the channel.
ItemDescription
