How to avoid parent pushing their own permissions to child with broken permissions

Question

The reason why new permissions added to a root folder in a SharePoint document library are also added to subfolders, even when inheritance is broken is that this option is selected by default. ("Share everything in this folder, even items with unique permissions")

We are using the Graph API to set permissions (https://learn.microsoft.com/en-us/graph/api/driveitem-invite?view=graph-rest-1.0&tabs=csharp)

Is there a way to pass the value of this checkbox via a Graph API request? In our case permissions added to a parent should never be inherited to children with broken inheritance. It seems the default for the checkbox is "true" when making API calls. How to override this?

Answer 1

It looks like you're dealing with a common issue when setting permissions in the SharePoint document library by using Graph API. By default, new permissions added to a root folder are inherited by subfolders, even if inheritance is broken. This is because the "Share everything in this folder, even items with unique permissions" option is selected by default.

Per my research, there isn't a direct way to pass the value of this checkbox via a Graph API request. In the "Send a sharing invitation", there are only following paraments can be set in the request.
