How can I add a link as attachment to the Premium Planner using Power Automate?

Hi @Rafael Nogueira 

Thank you for posting your question in the Microsoft Q&A forum.

Power Automate cannot directly “attach” a SharePoint folder to a Planner task, but it can add a link to the folder using a sharing link created in SharePoint.

Use this pattern in the flow after creating the folder and files:

1. Create a sharing link for the folder
   • Add the SharePoint action Create sharing link for a file or folder.
   • Point it to the document library and the folder that was just created.
   • Configure link type/scope as needed (for example, view-only vs. edit, and organization vs. anyone) as described under “Grant access using sharing links”.
   • This action returns a URL that can be used to access the folder.
2. Write the link into the Planner task
   • When creating or updating the Planner (Premium) task, use the URL returned from Create sharing link for a file or folder in the appropriate field that stores links/attachments for the task (for example, a link/URL field supported by the Planner Premium connector).
   • The task will then surface that URL as the “attachment” entry (a clickable link to the SharePoint folder).

Note: The SharePoint action Create sharing link for a file or folder only works with document libraries, not list items.
