You may start to see a notice when accessing your K2 for SharePoint integration in a SharePoint Online list or library. This notice states that SharePoint add-ins will be retired for SharePoint in Microsoft 365 in April 2026. Rest assured, our developers are hard at work and have already made strides in keeping your SharePoint Online integration working with your Nintex Automation (fka K2 Five) and K2 Cloud environments.
Revised March 2026 with the latest product release information
From K2 (5.7) on, new installs that integrate with SharePoint Online will use the new SharePoint Framework (SPFx) integration path. This includes a new way to manage your SharePoint Online integration in the Management site, and has updated the integration points per Microsoft’s guidance.
What about all our existing SharePoint integrations that use the add-in?
From K2 (5.8) on, there is a migration tool, to help you move your existing add-in based integrations for forms and workflows to the new SPFx model. This will allow customers who have previously activated the add-in integration to move over to the new supported model. If you are on an older version, start planning your upgrades today so you are ready to migrate your SharePoint Online solutions.
Full documentation is released and available to help you move your SharePoint Online solutions:
- If you are a K2 Cloud customer, see https://help.nintex.com/en-US/K2cloud/userguide/current/Content/K2-for-SharePoint/MigrationTool.htm.
- If you are a K2 on-premises customer, see https://help.nintex.com/en-US/nintexautomation/userguide/current/Content/K2-for-SharePoint/MigrationTool.htm

What if I’m using SharePoint on-premises?
If you are a Nintex Automation (K2 Five) customer and have integrated with SharePoint on-premises servers, nothing will change. All your solutions will continue to work. Microsoft is only deprecating the add-in model for SharePoint in Microsoft 365 (SharePoint Online).
As always, if you have any questions, reach out to your Nintex account representative.
