Permissions Not Visible in SharePoint Document Library Files Despite Being Set via Microsoft Graph API

Question

Hi everyone,

I’m working on a C# application using the Microsoft Graph API version 4.51.0 to manage permissions in a SharePoint site’s document library Files. The code successfully sets permissions programmatically, we also getting destination permission id as response but the changes are not reflected when checking the permissions in the SharePoint UI.

Here’s the code I’m using to set the permissions:

IDriveItemInviteRequest permissionRequest = SelectedDrive.Items[DestinationDriveId] .Invite(destinationUserPermissions, true, destinationPermissionRoles, false, null) .Request(); IDriveItemInviteCollectionPage invites = MicrosoftHelper.InvokeApiCall(() => { return permissionRequest.PostAsync().Result; }, this);

• SelectedDrive and DestinationDriveId are correctly initialized.
• destinationUserPermissions is a list of recipients (emails).
• destinationPermissionRoles contains roles like "write" or "read".
• MicrosoftHelper.InvokeApiCall is a helper to handle API calls and exceptions.

The issue: The API response indicates that permissions are being applied successfully (no errors or exceptions). However, when I check the SharePoint document library permissions in the UI, the changes are not visible.

Hi Yakun Huang-MSFT,

Thank you for your response.

I have tried using the following request to set site permissions: POST /sites/{siteId}/drive/items/{itemId}/invite

While the request appears to execute successfully, the changes are not reflected when I check the permissions in the SharePoint UI.

I have attached a screenshot for your reference. Please have a look.
