Working with SharePoint site resources

Article
09/29/2021

The SharePoint API in Microsoft Graph supports the following core scenarios:

Access to SharePoint sites, lists, and drives (document libraries)
Read-only support for site resources (no ability to create new sites)
Read-write support for lists, listItems, and driveItems
Address resources by SharePoint ID, URL, or relative path

The SharePoint API exposes three major resource types:

Site (this object)
List
ListItem

Tasks

All examples below are relative to https://graph.microsoft.com/v1.0.

Task name	Example Request
Get root site	GET /sites/root
Get site	GET /sites/{site-id}
Get site by path	GET /sites/{hostname}:/{site-path}
Get site for a group	GET /groups/{group-id}/sites/root
Search for sites	GET /sites?search={query}
Access the default document library for a site	GET /sites/{site-id}/drive
Enumerate the collection of document libraries under site	GET /sites/{site-id}/drives
Enumerate the lists under a site	GET /sites/{site-id}/lists
List root sites	GET /sites?filter=root ne null&select=siteCollection,webUrl
Search for sites	GET /sites?search={query}

Sites can also be addressed by path by using the SharePoint hostname, followed by a colon and the relative path to the site. You can optionally transition back to addressing the resource model by putting another colon at the end.

Path	Description
/sites/contoso.sharepoint.com:/teams/hr	The site associated with https://contoso.sharepoint.com/teams/hr
/sites/contoso.sharepoint.com:/teams/hr:/drive	Access the default drive for this site.

JSON representation

Here is a JSON representation of a site resource.

The site resource is derived from baseItem and inherits properties from that resource.

{
  "id": "string",
  "root": { "@odata.type": "microsoft.graph.root" },
  "sharepointIds": { "@odata.type": "microsoft.graph.sharepointIds" },
  "siteCollection": {"@odata.type": "microsoft.graph.siteCollection"},
  "displayName": "string",

  /* relationships */
  "contentTypes": [ { "@odata.type": "microsoft.graph.contentType" }],
  "drive": { "@odata.type": "microsoft.graph.drive" },
  "drives": [ { "@odata.type": "microsoft.graph.drive" }],
  "items": [ { "@odata.type": "microsoft.graph.baseItem" }],
  "lists": [ { "@odata.type": "microsoft.graph.list" }],
  "sites": [ { "@odata.type": "microsoft.graph.site"} ],
  "columns": [ { "@odata.type": "microsoft.graph.columnDefinition" }],

  /* inherited from baseItem */
  "name": "string",
  "createdDateTime": "datetime",
  "description": "string",
  "eTag": "string",
  "lastModifiedDateTime": "datetime",
  "webUrl": "url"
}

Note for existing SharePoint developers

The Microsoft Graph SharePoint API has a few key differences with the CSOM APIs. The site resource maps to SPWeb. The root site (SPWeb) in a site collection has a siteCollection facet, which contains information about the SPSite. Because IDs for sites are only unique within their site collection, addressing a site by ID requires providing both the site collection identifier and the site identifier.

GET https://graph.microsoft.com/v1.0/sites/{hostname},{spsite-id},{spweb-id}/

A URL constructed with only the hostname will point to the root site (SPWeb) in the default site collection.

GET https://graph.microsoft.com/v1.0/sites/{hostname}

A URL constructed with only the hostname and siteCollection (SPSite) ID will point to the root site (SPWeb) in the given site collection.

GET https://graph.microsoft.com/v1.0/sites/{hostname},{spsite-id}
