Delegated (personal Microsoft account)	Not supported.
Application	Chat.ReadBasic.All*, Chat.Read.All*, Chat.ReadWrite.All*

HTTP request

To get the signed-in user's chats in the organization using delegated permission:

GET /chats

To get the chats of the specified user (who is the signed-in user) in the organization using delegated permission:

GET /me/chats
GET /users/{user-id | user-principal-name}/chats

To get the chats of the specified user (who may not be signed in or is different from the signed-in user) in the organization, using application permission:

Optional query parameters

This method supports the following OData query parameters.

Name	Description
$expand	Currently supports members and lastMessagePreview properties.
$top	Controls the number of items per response. Maximum allowed $top value is 50.
$filter	Filters results.
$orderby	Currently supports lastMessagePreview/createdDateTime in descending order. Ascending order is currently not supported.

The other OData query parameters are not currently supported.

Note

The $top query parameter might not return all chats within a single response object. If the result set for all chats spans multiple pages, the response object includes an @odata.nextLink property that contains a URL to the next page of results. If that property is present, continue making additional requests with the @odata.nextLink URL in each response, until all the results are returned.

Request headers

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

Response

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