Send chatMessage in channel

Namespace: microsoft.graph

Send a new chatMessage in the specified channel.

Notes:

• We don't recommend that you use this API for data migration via the standard create message flow. For data migration scenarios, use the import messages flow instead.
• It's a violation of the terms of use to use Microsoft Teams as a log file. Only send messages that people will read.

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)	ChannelMessage.Send	Group.ReadWrite.All
Delegated (personal Microsoft account)	Not supported.	Not supported.
Application	Teamwork.Migrate.All	Not available.

Note

The Group.ReadWrite.All permission is supported only for backward compatibility. We recommend that you update your solutions to use an alternative permission listed in the previous table and avoid using these permissions going forward.

• Application permissions are only supported for migration. In the future, Microsoft may require you or your customers to pay additional fees based on the amount of data imported.

Example 2: Import a message

The following example shows how to import a message. For more information, see Import messages into Microsoft Teams chats and channels using Microsoft Graph.

Note: The permission scope Teamwork.Migrate.All is required for this scenario. The target channel must be in migration mode. The from property attributes the message to a user in the same tenant as the authenticated application. The createdDateTime value must be later than the channel createdDateTime and must not be in the future.

Important

The createdDateTime must be unique down to the millisecond within the target channel. If a message with the same createdDateTime exists, the request fails with 409 Conflict. Adjust the createdDateTime and retry. For more information, see Import messages into Microsoft Teams chats and channels using Microsoft Graph.

Request

The following example shows how to import back-in-time messages using the createdDateTime and from properties in the request body.
