## Overview

In this topic you will learn about all available methods for channel management.

**What are channels?** WhatsApp Channels are similar to Facebook pages, offering a space to share information, news, announcements, and other content related to a specific topic or entity. These channels can be created by a variety of entities, from football teams to streaming service companies, and allow users to follow and engage with content of their interest.

  It's important to emphasize that the pattern used by WhatsApp for channel IDs always includes the suffix **@newsletter**.
