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.

Teams are made up of channels, which are the conversations you have with your teammates. Each channel is dedicated to a specific topic, department, or project. Channels are where the work actually gets done - where text, audio, and video conversations open to the whole team happen, where files are shared, and where tabs are added.
