Azure Communication Services helps you to integrate communication into your applications. It supports various communication formats, such as

• Voice and Video

• Calling

• Rich Text Chat

• SMS

Azure Communication Services enables you to send and receive WhatsApp messages using the Azure Communication Services Messaging SDK. This SDK can be used to engage in conversation with a customer for product inquiry and customer service scenarios. It can also be used to send out messages like appointment reminders, shipping updates, two-factor authentication, and other notification scenarios. This feature is currently in public preview.

In this video, we perform a hands-on lab on creating "Azure Communication Services" resource in Azure Portal and sending messages to a WhatsApp account.
