listItem: delta

Namespace: microsoft.graph

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

Your app begins by calling delta without any parameters. The service starts enumerating the hierarchy of the list, returning pages of items, and either an @odata.nextLink or an @odata.deltaLink. Your app should continue calling with the @odata.nextLink until you see an @odata.deltaLink returned.

After you received all the changes, you can apply them to your local state. To check for changes in the future, call delta again with the @odata.deltaLink from the previous response.

The delta feed shows the latest state for each item, not each change. If an item was renamed twice, it only shows up once, with its latest name. The same item might appear more than once in a delta feed, for various reasons. You should use the last occurrence you see.

Items with this property should be removed from your local state.

Note: You should only delete a folder locally if it's empty after syncing all the changes.

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/{siteId}/lists/{listId}/items/delta

Query parameters

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

Parameter	Type	Description
token	String	If unspecified, enumerates the current state of the hierarchy. If latest, returns an empty response with the latest delta token. If a previous delta token, returns a new state since that token.

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 listItem objects in the response body.

In addition to a collection of listItem objects, the response also 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 more changes in the current set.
@odata.deltaLink	URL	A URL returned instead of @odata.nextLink after all current changes have been returned. 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 that contains one of the following error codes, and a Location header that contains a new nextLink that starts a fresh delta enumeration. This 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 has changed and a new token is required.

After the full enumeration is completed, compare the returned items with your local state and follow the instructions based on the error type.

Error type	Instructions
resyncChangesApplyDifferences	Replace any local items 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 items that the service didn't return and upload any items 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 details about how errors are returned, 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 of the items in the list already. This can be useful if your app only wants to know about changes and doesn't need to know about existing items. To retrieve the latest deltaLink, call delta with the query string parameter ?token=latest.
