Who can search for Cards in Slack?
Users who have a Guru license can search for Guru Cards in Slack and choose to share them in Slack Channels and DMs. Users without a Guru license will not be able to search for Guru Cards.
Who can view Cards in Slack?
Anybody with access to the Slack channel, even users without a Guru license, can view the content of your Guru Card in Slack in the following cases:
You send a Public Card link. The Guru App does not need to be in the channel.
You give the default Guru "All Members" Group access to the Collection that the Card lives in and the Guru App is invited to the channel.
You give the default Guru "All Members" Group access to the Board the Card lives in via Board Permissions and the Guru App is invited to the channel.
How do Cards appear when posted?
When you post a Card in Slack, you will see a preview of the Card (which includes the Card title, verification state, and option to view the Card in Slack or the web app) when:
The Guru app is in the channel
The person sending the Card has access to the Card
You are sharing a Public Card link
When the above criteria is not met, the Slack user will simply see the Card URL without a preview.
Guru will not show a preview of a Card in a Slack direct message unless you're sharing a Public Card.
