Best way of downloading Files off of SharePoint Online through Graph API?

Question

I have a requirement where I need to get all uploaded/attached files off of a SharePoint Online site(s). Which is the recommended way to do this?

Currently I'm accessing the metadata for a Sites files through

GET /sites/{id}/drives
GET /drives/{drive-id}/items/root/children
GET /drives/{drive-id}/items/{item-id}/children

and downloading the contents through

GET /drives/{drive-id}/items/{item-id}/content

and so on.

Was just wondering if there's anything I'm missing or if there's a "better" way of doing this please?

Hi @Adz ,

I tested the below Graph API endpoints in Graph Explorer and Postman to download a specific file from SharePoint document library. You can use any of the below Graph APIs and also refer/use other additional APIs which are provided in this documenation as per your requirement:

GET https://graph.microsoft.com/v1.0/sites/{site-id}/lists/{list-id}/items/{item-id}/driveItem/content  

Example:

GET https://graph.microsoft.com/v1.0/sites/{site-id}/drives/{drive-id}/root:/{item-path}  

Here {item-path} can be /{file-name}
You can use the field “@microsoft.graph.downloadUrl” in order to download the file in your application.
