“I’d like to restore original permissions on all documents in a SharePoint library, how can I list files with unique permissions in a Power Automate flow?”
When restoring library permissions, it’ll remove all unique permissions on the library itself and use the site permissions instead. But that doesn’t mean it’ll restore permissions also on all the files in that library. If the permission inheritance is broken, the library settings doesn’t have any effect on such files.
Yet often you want to restore all permissions, on all the folders and all the files. How do you do that? How do you list all the files/folders with unique permissions to inherit them again?
Get the files with an HTTP request
The good news is that each file in the document library has a property called ‘HasUniqueRoleAssignments’ that’ll give you such information. The bad news is that this property is not accessible using the ‘Get files (properties only)’ action. As such, you’ll need an HTTP request to SharePoint where you’ll ask for this property specifically with the $select parameter. Since you’ll need also the id of the item to restore the permissions, take also the id.
Method: GET Uri: _api/web/lists/getByTitle('<libraryName>')/items?$select=HasUniqueRoleAssignments,id
Notes: <…> are placeholders, replace them including the < and >. If you’d like also the file name/path/type you can add the corresponding properties to the $select.
This action will return all files in the library, not only the ones with unique permissions…
You’ll have to filter the results using the ‘Filter array’ action to keep only files whose ‘HasUniqueRoleAssignments’ equals true.
Navigate in the HTTP request output to get the array with the results…
…and keep only the files whose HasUniqueRoleAssignments is true.
The result will be only files with unique permissions. As you have their id, you can restore them to the original permissions – file by file, folder by folder.
To restore permissions on all files and folders in a SharePoint library, you must know ids of these files. And even though Power Automate doesn’t have a dedicated action that would list those documents with unique permissions, there’s still an HTTP request to save the day. List all the files including the ‘HasUniqueRoleAssignments’ property, filter only the ones where it’s true, and restore the permissions with another HTTP request.
