Unable to Retrieve SharePoint List Item Attachments in .NET Core using Graph API

Question

In SharePoint Online, when retrieving list items using Graph Explorer, the Attachments property only returns a boolean value (true or false), indicating whether an item has attachments. However, it does not provide direct links to attached files such as images, PDFs, or text documents.

However, Graph Explorer does not support the Attachments property.

I need help in retrieving attachment links for list items in SharePoint Online using the Microsoft Graph API using C#.

Hi @EdbergVasan DallasVaz ,

Good days, thanks for posting in this forum.

Unfortunately, it is currently impossible to obtain the URL of the attachment in the List item through the API. As you said, it only returns a Boolean value. But you can try to use Power Shell to obtain relevant information about Attachments:

Non-official, just for reference.

you can try to use below API:

GET /sites/{site-id}/lists/{list-id}/items/{item-id}/driveItem
