Product: Microsoft Graph API
Device & OS: not provided
Scenario: Automating or developing an application that requires adding file attachments to a SharePoint list.

Alternative: Use PnP PowerShell to Add List Item Attachments

Since Microsoft Graph API does not natively support list item attachments, using the Add-PnPListItemAttachment cmdlet in PnP PowerShell is the recommended workaround.

Microsoft Graph can create list items and update their fields, but it currently cannot attach files to them. Developers rely on alternative endpoints or tools like PnP PowerShell to accomplish this.

Install and Connect PnP PowerShell

Open your PowerShell console and connect to your SharePoint site using the command: Connect-PnPOnline -Url 'https://yourtenant.sharepoint.com/sites/yoursite' -Interactive.

Execute the Attachment Cmdlet

Use the Add-PnPListItemAttachment cmdlet. You will need to specify the List name, the Item ID, and the Path to the local file you want to upload.

Verify the Upload

Navigate to your SharePoint list in the web browser and check the specific list item to ensure the attachment has been successfully uploaded and linked.

Frequently Asked Questions

Can Microsoft Graph create SharePoint list items without attachments?

Yes, Microsoft Graph fully supports creating new list items and updating their text, number, or choice fields. The current limitation only applies to uploading file attachments directly to those items.

Is there a REST API alternative for uploading SharePoint list attachments?

Yes, you can use the traditional SharePoint REST API endpoint (/_api/web/lists/getbytitle('ListName')/items(ItemID)/AttachmentFiles/add) to upload attachments, which remains functional despite the Graph API limitation.

When will Microsoft Graph support SharePoint list attachments natively?

There is currently no official release date. Microsoft relies on user feedback from the Microsoft 365 Developer Platform to prioritize feature development, so voting for the respective feature request is highly recommended.
