Admins on Team and Enterprise plans can share an invite link that lets teammates join the organization directly—without requiring individual email invitations.
For admins: Set up and share an invite link
Who can manage invite links
Admins and above can generate, copy, disable, and regenerate the invite link for their organization.
Availability
Team plans: Invite links are enabled by default for new organizations.
Enterprise plans (non-SSO): Invite links are disabled by default. Admins can enable them from Organization settings > Organization.
SSO organizations: Invite links are not available. Member provisioning is managed through your Identity Provider.
Find and share your invite link
Navigate to Organization settings > Organization.
Find the invite link section and click "Copy invite link."
Share the link with the teammates you'd like to add—for example, in a Slack channel, email thread, or team wiki.
Important: Invite links expire automatically 90 days after creation, so you’ll need to regenerate the link when this happens so prospective members can use it.
Manage your invite link
Action | What it does |
Disable the link | Immediately invalidates all existing links. No one can join via link until it's re-enabled. |
Regenerate the link | Creates a new link and immediately invalidates the previous one. |
How seat assignment works
Members who join via link are assigned to the lowest available seat tier. If no seats are available, a standard seat is created automatically.
Security
Invite link joins respect your organization's existing security controls:
Allowed domains: Only users with an email address on your organization's allowed domains list can join. Anyone else will see an error.
Org addition setting: If your organization requires admin approval for new members ("request + approve" mode), link joiners will submit a request that you'll need to approve before they're added. If set to "automatic," they're added immediately.
Seat limits: If your organization has reached its seat limit, link joiners will see an error prompting them to contact their admin.
For members: Join via an invite link
Click the invite link your admin shared.
If you're not already logged in, you'll be prompted to sign up or log in.
After authenticating, your email domain will be checked against your organization's allowed domains.
If your domain matches, you can proceed to join.
If your domain doesn't match, you'll see an error. Contact your admin if you believe this is incorrect.
What happens next depends on your organization's settings:
If your organization uses instant approval, you’ll be added to the lowest available seat tier automatically when you join using the invite link.
If your organization uses request + approve, joining via the invite link sends a request to your admin, who needs to review and approve it before you’re added as a member.
For more information, see How to find and join an organization.
If you're already a member of the organization, you'll be redirected to the chat interface automatically.
Note: If the link has been disabled or regenerated by your admin, it will no longer work. Ask your admin to share a new link.
