I am trying to get the all the folders from SharePoint library using Graph API. But I am able to get only level one folder

  • Folder 1
    • Folder 1 Sub Folder
  • Folder 2
    • Folder Sub Folder

Using below code able to get Folder 1 and Folder 2 not sub folders names

https://graph.microsoft.com/v1.0/sites('a22d0d0a-68fb-40b3-9ef7-8001e691a')/lists('8af98cb6-bbf3-4599-b093-7287bcef')/drive/root/children

Is it possible using graph API to get the all the folders

You could try the below endpoint to get all folders in the SharePoint Document library:

https://graph.microsoft.com/v1.0/sites/{site-id}/lists/{list-id}/items?$expand=fields&$filter=fields/ContentType eq 'Folder'

And you need to add request header Prefer: HonorNonIndexedQueriesWarningMayFailRandomly

enter image description here

  • It show below error messages "message": "Field 'ContentType' cannot be referenced in filter or orderby as it is not indexed. Provide the 'Prefer: HonorNonIndexedQueriesWarningMayFailRandomly' header to allow this, but be warned that such queries may fail on large lists.", "innerError": { Mar 16, 2021 at 8:53
  • As I said, you need to add the request header Prefer: HonorNonIndexedQueriesWarningMayFailRandomly Mar 16, 2021 at 8:55
