Article
2024-04-05

Namespace: microsoft.graph

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 channel.

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.

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.

HTTP request

POST /teams/{team-id}/channels/{channel-id}/messages

Request headers

Examples

Example 1: Create a message in a specified channel

For a more comprehensive list of examples, see Create chatMessage in a channel or a chat.

Request

The following example shows a request.

Important

Microsoft Graph SDKs use the v1.0 version of the API by default, and do not support all the types, properties, and APIs available in the beta version. For details about accessing the beta API with the SDK, see Use the Microsoft Graph SDKs with the beta API.

For details about how to add the SDK to your project and create an authProvider instance, see the SDK documentation.
