Wazzup chats is a conversation window from which you can correspond with clients on WhatsApp, Instagram, Telegram.
You can use Wazzup chats:
Regardless of where you open Wazzup chats, they look equally stylish and have the same functionality.

Wazzup chat has the classic messenger look, with a list of chats on the left and a correspondence box on the right. In the mobile app, there is a list of chats on the home screen, and when you click on it, a dialog box opens.
There are two types of Wazzup chats: general and individual. The general chat shows all dialogs available to the employee, and the individual chat shows dialogs with those contacts who are in the deal.
What dialogs will be displayed in the general chat of the employee, you determine in the integration settings. You can use the general chat in the CRM, personal account, and mobile app.
To enter the general chat, click the Wazzup button in the top bar of the interface. The location of the Wazzup button depends on how often you use the service. If you do, it will be in the visible part of the panel. If not, click the ellipsis and look for the button in the drop-down list. 
To write to a customer from a Wazzup individual chat, go to the lead, contact or deal card. In the upper right corner, click the "Wazzup" button.

In WhatsApp and Telegram you can write first. To do this, you only need the client's phone number.
1. Click the Wazzup button in the upper right corner of the contact card:

2. A chat with the client will appear. If the manager has several numbers available, the chat will be created from the seller's priority number.
If you need to write from another number: click on the arrow next to the contact's name in the chat list → create a chat from the desired number by clicking the "+ Create dialogue" button.
