A general practice followed is to use several tools to make a basic customer call. But what if WhatsApp allowed you to make those calls without switching between apps?
Well, now with WhatsApp Business Calling API, you can make real-time voice calls straight from your business system. Over 2 billion users already trust the app, and this feature, which is only available in the Business version, simplifies your business communication.
In this blog, we’ll learn what the WhatsApp Business Calling API is and how it can help you transform your business communication.
What Is WhatsApp Business Calling API?
WhatsApp Business Calling API is a new feature that helps businesses make real-time voice calls directly from the WhatsApp Business platform. This API was created especially for businesses to manage customer calls smoothly within their current systems. This is in contrast to the standard WhatsApp, which is primarily used for messaging.
With WhatsApp API, businesses can integrate voice calling into their customer support or sales systems. And the best part, they can make and receive calls without leaving the app.
Benefits Of WhatsApp Business Calling API?
WhatsApp Business Calling API takes customer engagement to the next level by integrating voice calls directly into the WhatsApp platform. But what makes it so powerful? Let’s understand it by going through its key benefits:
1. Integration with Existing Systems
You can incorporate voice calls into your CRM or customer service systems using the WhatsApp Business Calling API. As a result, you can save time and minimize friction by managing calls, chats, and customer inquiries all on the same platform.
2. Improved Customer Engagement
Customers love convenience. And WhatsApp is already a platform they trust for messaging. So, adding the voice calls feature into the mix offers a more personal interaction. It helps in building stronger relationships and increases customer satisfaction.
3. Cost-Efficient Communication
Especially for international calls, WhatsApp Business Calling reduces the cost of communication. You won’t have to worry about a costly phone bill. Just have a stable internet connection.
4. Real-Time Support and Faster Resolutions
As compared to text, voice calls resolve customer queries more quickly. So by allowing your team to make real-time calls, you can fix the customer issue faster. Furthermore, this improves your overall customer support experience, particularly effective for handling customer service escalations.
5. Access to Analytics and Insights
With the WhatsApp voice call API, businesses can monitor and examine call data to enhance their operations. To improve your communication tactics, you can track call volumes, response times, and customer satisfaction.
6. Secure Communication
This feature protects sensitive customer data and ensures that calls are encrypted. This will increase consumer trust and assist businesses in adhering to industry regulations. Customers will also value the assurance that their calls are private and their information is safe with you.
How Does WhatsApp Business Calling API Work?
Let’s break down the working of WhatsApp Business Calling API into simple terms:
Let’s suppose you are running a customer support team, and your customers are messaging you on WhatsApp. Use the WhatsApp call API feature now rather than typing the answers or moving them to a different system for calls.
The WhatsApp voice call API is a call made directly from your system. You don’t need a separate phone system or app. Like any other phone call, this one is conducted via WhatsApp.
And, during a call, you can view customer information, take notes, and manage the conversation using the tools you have in your WhatsApp Business interface. This can also apply to a free entry point conversation, which allows businesses to respond without incurring upfront charges.
After a call, you can monitor customer satisfaction, call duration, and response times. It gives you useful information to enhance subsequent communications. This also provides opportunities for better lead generation by understanding which conversations convert to calls.
