# Overview

<Warning>
  **Constraint:**

  1. Conversations will not be updated once the size of the group exceeds 300.
  2. A conversation can have up to 25 tags with 100 characters per tag.
</Warning>

<Info>
  Conversations provide the last messages for every one-on-one and group conversation the logged-in user is a part of. This makes it easy for you to build a Recent Chats list.
