Important

APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.

Get a set of newly created, updated, or deleted sites without having to perform a full read of the entire sites collection.

A delta function call for sites is similar to a GET request, except that by appropriately applying state tokens in one or more of these calls, you can query for incremental changes in the sites. It allows you to maintain and synchronize a local store of a user's sites without having to fetch all the sites from the server every time. The application calls the API without specifying any parameters. The service begins enumerating sites and returns pages of changes to these sites, accompanied by either an @odata.nextLink or an @odata.deltaLink. Your application should continue making calls using the @odata.nextLink until there's an @odata.deltaLink in the response.

After you receive all the changes, you can apply them to your local state. To monitor future changes, call the delta API by using the @odata.deltaLink in the previous response.

Any resources marked as deleted should be removed from your local state.

This API is available in the following national cloud deployments.

Global service	US Government L4	US Government L5 (DOD)	China operated by 21Vianet
✅	✅	✅	✅

Permissions

Choose the permission or permissions marked as least privileged for this API. Use a higher privileged permission or permissions only if your app requires it. For details about delegated and application permissions, see Permission types. To learn more about these permissions, see the permissions reference.

Permission type	Least privileged permissions	Higher privileged permissions
Delegated (work or school account)	Sites.Read.All	Sites.ReadWrite.All
Delegated (personal Microsoft account)	Not supported.	Not supported.
Application	Sites.Read.All	Sites.ReadWrite.All

HTTP request

GET /sites/delta

Query parameters

In the request URL, you can include the following optional query parameter.

Parameter	Type	Description
token	String	If the value is `latest`, the call returns an empty response with the latest delta token. If the value is a previous delta token, the call returns the new state since that token was issued.

This method also supports the $select, $expand, and $top OData query parameters to customize the response.

Request headers

Header	Value
Authorization	Bearer {token}. Required. Learn more about authentication and authorization.

Request body

Don't supply a request body for this method.

Response

If successful, this method returns a 200 OK response code and a collection of site objects in the response body.

In addition to the collection of site objects, the response includes one of the following properties.

Name	Value	Description
@odata.nextLink	URL	A URL to retrieve the next available page of changes if there are other changes in the current set.
@odata.deltaLink	URL	A URL returned instead of @odata.nextLink after all current changes are returned. You can use this property to read the next set of changes in the future.

In some cases, the service returns a 410 Gone response code with an error response containing one of the following error codes and a Location header with a new nextLink that starts a fresh delta enumeration. This error occurs when the service can't provide a list of changes for a given token; for example, if a client tries to reuse an old token after being disconnected for a long time or if the server state changed and a new token is required.

After you complete the full enumeration, you can compare the returned sites with your local state and follow the instructions based on the error type.

Error type	Instructions
resyncChangesApplyDifferences	Replace any local sites with the versions from the server (including deletes) if you're sure that the service was up-to-date with your local changes when you last synchronized. Upload any local changes that the server doesn't know about.
resyncChangesUploadDifferences	Upload any local sites that the service didn't return and upload any sites that differ from the versions from the server. Keep both copies if you're not sure which one is more up-to-date.

In addition to the resync errors and for more information, see Microsoft Graph error responses and resource types.

        }
    ]
}

Example 3: Delta link request

In some scenarios, you might want to request the current deltaLink value without first enumerating all the sites, lists, and webs. This suggestion can be useful if your app only wants to know about changes and doesn't need to know about existing sites. To retrieve the latest deltaLink, call delta with the query string parameter ?token=latest.

Note: To maintain a full local representation of the resources, you must use delta for the initial enumeration. Using delta is the only way to guarantee that you've read all of the data you need to.

Request

The following example shows a request.

GET https://graph.microsoft.com/beta/sites/delta?token=latest


// Code snippets are only available for the latest version. Current version is 5.x

// To initialize your graphClient, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=csharp
var result = await graphClient.Sites.Delta.GetAsDeltaGetResponseAsync((requestConfiguration) =>
{
	requestConfiguration.QueryParameters.Token = "latest";
});
