Working with the cloud communications API in Microsoft Graph

The Microsoft Graph cloud communications API adds a new dimension to how you or your organization can interact with other users by enabling core communication capabilities and features in your apps and services. You can use this API to create and receive calls as well as create and retrieve meeting coordinates.

You can use the cloud communications API to build service applications (bots) that act like participants in a call, and that create and retrieve meetings on behalf of users. This API provides calling functionality as well as the ability to create and retrieve online meetings. You can use service applications (bots) with this API, where the bot can act as a participant in your VoIP calls or Microsoft Teams meetings, for example.
