chatMessage: delta

Namespace: microsoft.graph

Retrieve the list of messages (without the replies) in a channel of a team. By using delta query, you can get new or updated messages in a channel.

Note: Delta will only return messages within the last eight months. You can use GET /teams/{team-id}/channels/{channel-id}/messages to retrieve older messages.

Delta query supports both full synchronization that retrieves all the messages in the specified channel, and incremental synchronization that retrieves those messages that have been added or changed in the channel since the last synchronization. Typically, you would do an initial full synchronization, and then get incremental changes to that messages view periodically.

To get the replies for a message, use the list message replies or the get message reply operation.

A GET request with the delta function returns either:

• A @odata.nextLink (that contains a URL with a delta function call and a skipToken), or
• A @odata.deltaLink (that contains a URL with a delta function call and deltaToken).

State tokens are opaque to the client. To proceed with a round of change tracking, copy and apply the @odata.nextLink or @odata.deltaLink URL returned from the last GET request to the next delta function call for that same calendar view. A @odata.deltaLink returned in a response signifies that the current round of change tracking is complete. You can save and use the @odata.deltaLink URL when you begin to retrieve more changes (messages changed or posted after acquiring @odata.deltaLink).

For more information, see the delta query documentation.

This API is available in the following national cloud deployments.

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)	ChannelMessage.Read.All	Group.Read.All, Group.ReadWrite.All
Delegated (personal Microsoft account)	Not supported.	Not supported.
Application	ChannelMessage.Read.Group	ChannelMessage.Read.All, Group.Read.All, Group.ReadWrite.All

Note

The ChannelMessage.Read.Group permission uses resource-specific consent.

HTTP request

GET /teams/{team-id}/channels/{channel-id}/messages/delta

Query parameters

Tracking changes in channel messages incurs a round of one or more delta function calls. If you use any query parameter (other than $deltatoken and $skiptoken), you must specify it in the initial delta request. Microsoft Graph automatically encodes any specified parameters into the token portion of the @odata.nextLink or @odata.deltaLink URL provided in the response.

You only need to specify any query parameters once upfront.

In subsequent requests, copy and apply the @odata.nextLink or @odata.deltaLink URL from the previous response, as that URL already includes the encoded parameters.

Query parameter	Type	Description
$deltatoken	string	A state token returned in the @odata.deltaLink URL of the previous delta function call, indicating the completion of that round of change tracking. Save and apply the entire @odata.deltaLink URL including this token in the first request of the next iteration of change tracking for that collection.
$skiptoken	string	A state token returned in the @odata.nextLink URL of the previous delta function call, indicating that there are further changes to be tracked.

Optional OData query parameters

The following OData query parameters are supported by this API:

• $top represents the maximum number of messages to fetch in a call. The upper limit is 50.
• $skip represents how many messages to skip at the beginning of the list.
• $filter allows returning messages that meet a certain criteria. The only property that supports filtering is lastModifiedDateTime, and only the gt operator is supported. For example, ../messages/delta?$filter=lastModifiedDateTime gt 2019-02-27T07:13:28.000z will fetch any reply chain (each channel post message and associated reply messages) created or changed after the specified date time.
• $expand allows expanding properties for each channel message. Only replies is supported. If a channel message contains more than 1000 replies, replies@odata.nextLink is provided for pagination.

Note: For $expand query parameter, please refer to List Channel Messages.

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 chatMessage objects in the response body. The response also includes a @odata.nextLink URL or a @odata.deltaLink URL.

Examples

Example 1: Initial synchronization

The following example shows a series of three requests to synchronize the messages in the given channel. There are five messages in the channel.

• Step 1: initial request and response.
• Step 2: second request and response
• Step 3: third request and final response.

For brevity, the sample responses show only a subset of the properties for an event. In an actual call, most event properties are returned.

See also what you do to retrieve additional changes.

Initial request

In this example, the channel messages are being synchronized for the first time, so the initial sync request does not include any state token. This round returns all the events in that calendar view.

The request specifies the optional request header, odata.top, returning 2 events at a time.
