# Introduction

The Channels API centralizes access to CM.com's conversational Channels onboarding and configuration processes.\
Many of the API's functionalities are also available via the [Channels ](https://www.cm.com/app/channels) application.

Almost all endpoints are focused around single account configuration, therefore you will find the first path variable to provide is your "*accountId*".\
This unique GUID represents an account within your organization, not you as a user. Identification and authentication is further explained [here](https://developers.cm.com/messaging/docs/channels-api/authentication).
