Fetch Documents From SharePoint Document Library Using Microsoft Graph API

This article covers detailed insights on how you can fetch document/file details residing in a SharePoint document library using Microsoft graph API

All the graph API calls in this article are performed here.

Any developer can use the same graph API in the code solution of their choice either in .NET, JavaScript/TypeScript, or any coding language of their choice

Note: Make sure to register an app with the following API permissions whenever you add API to fetch the documents from SharePoint document library in your code solution: Sites.Read.All, Sites.ReadWrite.All, Files.Read.All, Files.ReadWrite.All

For fetching documents from SharePoint document library, I have divided this into 3 API calls to make it more dynamic so that anyone can consume this directly to their code solution.

Fetching Site ID based on Site name:

Navigate to Graph explorer here.

Sign in to Graph explorer

Select GET and v1.0 then add this API: https://graph.microsoft.com/v1.0/sites/{tenantdomainname}.sharepoint.com:/sites/{sitename}

Replace tenantdomainname: Your tenant domain name

Replace sitename: Site name of the site where the document library resides

If your API call is correctly written, you will get 200 as API’s response with the details as shown below

Now, from the API response fetch the value of parameter id, this is the site ID that we will consume in the second step

Fetching document library (list) ID:

Navigate to graph explorer and sign in

Select GET and v1.0 then add this API:

https://graph.microsoft.com/v1.0/sites/{siteID}/lists?$filter=displayName+eq+'{LibraryName}'

Replace siteID: value fetched from the above API call

Replace LibraryName: Name of the library from which you wish to fetch the documents

If your API call is correctly written, you will get 200 as API’s response with the details as shown below

Now, from the API response grab the value of id from the value object (i.e. value.id will be your Document Library ID). This document library ID will be consumed as driveID in the next step

Using site ID and library/list ID fetch documents

Navigate to graph explorer and sign in

Select GET and v1.0 then add this API:

https://graph.microsoft.com/v1.0/sites/{siteID} /drives/{driveID} /root/children

Replace siteID: from Step 1 API response

Replace driveID: from Step 2 API response
