WhatsApp Business Calling API enables a business to make and receive voice calls with their customer via WhatsApp. It facilitates communication to the level that customer service systems have been able to integrate voice support making the communication flow more effectively and in real time. The comprehension of this API implies understanding that it helps to provide customers with a better experience and shorter response time, as well as a more personal and convenient method of communication. 

• An API allows calls to be made through VoIP as part of the Cloud API version of the WhatsApp Business.
• Facilitates both customer-dialed and business-dialed voice communications, the former with no cost for receiving calls, the latter with consent, with an opt-in permission process. 

Why It Is Important 

1. Customer Journey One-App 

Chatter brings all messages, calls, and threads under one roof- there is no longer a switch in context with channels.  

2. Increased User Experience 

The convenience of a seamless transition between chat and Voice support to bring greater clarity to critical queries is identified to be expected by an average of about 76 percent of consumers. 

3. Trust & Verification 

Business accounts presenting the brand (logo, name, blue tick) are more trusted by the users and result in fewer calls being rejected. 

4. Secure & Encrypted 

This forms end-to-end encrypted communications based on WebRTC that are privacy-friendly and compliant with regulations. 

5. Operational Efficiency 

Call handling is done through permissions, IVR support, call icons and business-hours controls- making work more efficient.

Final Thoughts 

WhatsApp Business Calling API, offered by Meta, fills a gap between the text and voice experience, bringing more faceted experiences to customers, as well as speeding up the process and increasing trust since calls can be identified as authorized and safe. Having access to communication that is centralized within WhatsApp enables businesses to scale support as well as sales, engaging more in context. When you are willing to enhance your customer experience, incorporate a calling partner with a BSP, get certified, train your staff, and introduce pilots. Convenience, human touch provided on top of regular interactions, can make the latter loyalty-creating activities.
