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.
Send a new chatMessage in the specified chat. This API cannot create a new chat; you must use the list chats method to retrieve the ID of an existing chat before creating a chat message.
Note: We don't recommend that you use this API for data migration. It does not have the throughput necessary for a typical migration.
Note: It is a violation of the terms of use to use Microsoft Teams as a log file. Only send messages that people will read.
