Accessing shared DriveItems

Access a shared DriveItem or a collection of shared items by using a shareId or sharing URL.

To use a sharing URL with this API, your app needs to transform the URL into a sharing token.

Permissions

One of the following permissions is required to call this API. To learn more, including how to choose permissions, see Permissions.

Permission type Permissions (from least to most privileged)
Delegated (work or school account) Files.ReadWrite, Files.ReadWrite.All, Sites.ReadWrite.All
Delegated (personal Microsoft account) Files.ReadWrite, Files.ReadWrite.All
Application Files.ReadWrite.All, Sites.ReadWrite.All

HTTP request

GET /shares/{shareIdOrEncodedSharingUrl}

Path parameters

Parameter Name Value Description
shareIdOrEncodedSharingUrl string Required. A sharing token as returned by the API or a properly encoded sharing URL.

Encoding sharing URLs

To encode a sharing URL, use the following logic:

  1. First, use base64 encode the URL.
  2. Convert the base64 encoded result to unpadded base64url format by removing = characters from the end of the value, replacing / with _ and + with -.)
  3. Append u! to be beginning of the string.

As an example, to encode a URL in C#:

string sharingUrl = "https://onedrive.live.com/redir?resid=1231244193912!12&authKey=1201919!12921!1";
string base64Value = System.Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes(sharingUrl));
string encodedUrl = "u!" + base64Value.TrimEnd('=').Replace('/','_').Replace('+','-');

Optional request headers

Name Type Description
Prefer string Optional. Set to one of the prefer values documented below.

Prefer header values

Name Description
redeemSharingLink If the shareIdOrEncodedSharingUrl is a sharing link, grant the caller durable access to the item
redeemSharingLinkIfNecessary Same as redeemSharingLink, but access is only guaranteed to be granted for the duration of this request

redeemSharingLink should be considered equivalent to the caller navigating to the sharing link the browser (accepting the sharing gesture), whereas redeemSharingLinkIfNecessary is intended for scenarios where the intention is simply to peek at the link's metadata.

Response

If successful, this method returns a 200 OK response code and a sharedDriveItem resource in the response body.

Example

Request

Here is an example of the request to retrieve a shared item:

GET /shares/{shareIdOrEncodedSharingUrl}

Response

Here is an example of the response.

HTTP/1.1 200 OK
Content-type: application/json

  "id": "B64397C8-07AE-43E4-920E-32BFB4331A5B",

SDK sample code


GraphServiceClient graphClient = new GraphServiceClient( authProvider );

var sharedDriveItem = await graphClient.Shares["{shareIdOrEncodedSharingUrl}"]
	.Request()
	.GetAsync();

Read the SDK documentation for details on how to add the SDK to your project and create an authProvider instance.

Access the shared item directly

While the SharedDriveItem contains some useful information, most apps will want to directly access the shared DriveItem. The SharedDriveItem resource includes a root and items relationships which can access content within the scope of the shared item.

Example (single file)

Request

By requesting the driveItem relationship, the DriveItem that was shared will be returned.

GET /shares/{shareIdOrUrl}/driveItem

Response

HTTP/1.1 200 OK
Content-Type: application/json

{
  "id": "9FFFDB3C-5B87-4062-9606-1B008CA88E44",

  "file": {},
  "size": 109112
}

SDK sample code


GraphServiceClient graphClient = new GraphServiceClient( authProvider );

var driveItem = await graphClient.Shares["{shareIdOrUrl}"].DriveItem
	.Request()
	.GetAsync();

Read the SDK documentation for details on how to add the SDK to your project and create an authProvider instance.

Example (shared folder)

Request

By requesting the driveItem relationship and expanding the children collection, the DriveItem that was shared will be returned along with the files within the shared folder.

GET /shares/{shareIdOrUrl}/driveItem?$expand=children

Response

HTTP/1.1 200 OK
Content-Type: application/json

Remarks

  • For OneDrive for Business and SharePoint, the Shares API always requires authentication and cannot be used to access anonymously shared content without a user context.
