How to make calls on WhatsApp using the WhatsApp API

One of the latest updates made, which are very popular nowadays, are voice calls on WhatsApp through the use of the official API.

The most important and interesting element is that we are not talking about voice notes, but about real calls directly on WhatsApp. We know very well that the app already had this functionality, but not in its Business version. This means that companies, which have always used external tools for this task, now have the possibility of calling on WhatsApp Business precisely through the API.

With the aforementioned, WhatsApp will have a wide range of business tools to offer and will be much easier to use to communicate effectively with all customers.

What is the WhatsApp API and what is it for?

The WhatsApp API is a tool that allows all companies to implement WhatsApp features directly and completely customized within their systems and apps.

It would be like building a bridge between your business and the instant messaging platform, providing various possibilities to improve communication and interaction with your customers.

Benefits of using WhatsApp API for Calls

There are many benefits of having an open voice channel when your business can offer highly personalized customer service. There is a reason why banks can be considered pioneers in this type of service. That is why we want to tell you all the benefits of using WhatsApp API for calling.

Here are some of the major benefits:

• No need to depend on external tools
• Efficient communication for sales
• Improved customer service
• Centralized interaction
• Convenience and accessibility
• Secure and private
• Profitable

We really hope that these benefits can make you fully understand how interesting calling with WhatsApp API is. It will finally be possible to communicate more effectively and, at the same time, it allows companies like banks or call centers to implement WhatsApp as one of the main communication channels.

Useful requirements to use the API with Callbell

To start this process of integrating the WhatsApp API, you will need to do it through a BSP like Callbell. In order to use the API, the following requirements are necessary:

• An account on Meta Business Manager with an associated payment method.
• A phone number to associate with the WhatsApp API.

As for the Meta Business Manager, it must be properly filled in with the company data in the “Company information” section, to which the WhatsApp API account will be associated. Among them, the company's website must be included. The latter must be active and easily reachable (without this requirement, the WhatsApp API account will be deactivated within a few hours).

In addition, it will be necessary to associate a valid payment method with the Meta Business Manager in order to allow Meta to invoice the cost that the WhatsApp API line will generate. The aforementioned implementation will be carried out only at the end of the activation process.

Verification by Meta Business Manager is not mandatory. This feature allows you to overcome some limits on the number of outgoing interactions from a single WhatsApp account and could be done after activating the line.

As for the phone number that will be associated with the WhatsApp Cloud API, it can be a mobile or landline number so as to receive a verification SMS or call and that is not associated with any WhatsApp/WhatsApp Business account at the time of activation.

What kind of calls can we make?

Business-initiated calls

Business-to-customer calls are now available in Brazil, Mexico, and India. You can also call WhatsApp users, but only with their permission.

These types of calls allow the company to send a permission request on WhatsApp to the user they want to interact with. The user must then accept the permission. You can submit 1 permission request in 24 hours and 2 per week. Once the user accepts, the company will have up to 72 hours to make the call.

International calls

You can reach users from all over the world without worrying about high costs or delays, giving them the same experience, with the same quality, no matter where they are.

The WhatsApp call screen will display the name of the company and a verified badge, so users will know it is you and your company.

Conclusion

Voice calls on WhatsApp are revolutionizing the entire world, improving the way companies can communicate with their customers, by creating personalized spaces to communicate, efficiently. This can help improve relationships, solving all the problems that may arise, whether they are simple doubts, or the possibility of offering information and much more.
