Unfurling Slack Record Layouts with Data Sharing Options

You can configure how unfurled links appear in Slack using Unfurling Slack Records and configuring data sharing options.

Unfurling Options	Description	Preview
Do Not Share Data	The most secure option. A preview of the data isn’t shared to the channel.	The link isn’t unfurled.
Preview Button Only	Display only a preview button to open a window containing the record details. The window opens with the viewer’s permissions. Data isn’t displayed in the channel.
Object Type and Preview Button	Display the record's object type and a preview button to open a window containing the record details. The window opens the viewer's permissions.
Data Viewable by Slack Default Render User	Display the record in the channel according to the permissions of the Default Render User.
Name, Type, and Preview Button	Display the record’s object type, name, and a preview button to open a window containing the record details. The window opens the viewer’s permissions.
Data Viewable by User Sharing the Link	Display the record in the channel according to the permissions of the user posting the link.

When setting up data sharing options in Salesforce Setup there are two unfurling options a Slack Record Layout applies to.

Data Viewable by Slack Default Render User

Data Viewable by User Sharing the Link

When either option is selected, unfurling initially looks for an Unfurling Slack Record Layout for the Object Type referenced by the shared link. If there isn’t a Slack Record Layout assigned to the user for that Object Type, then the object's Compact Layout is used to determine which fields to show in the link preview content.
