One of the most important things in marketing is having a list of contacts with valid phone numbers. This is because, if you want to contact your leads, you will be able to do it through SMS messages. However, if you are not sure about how many phone numbers are valid in your database, you will not be able to reach your leads and therefore, your business will not grow as much as it could.

Fortunately, nowadays there are many ways to check whether a phone number is valid or not, and one of them is by using a WhatsApp business API. These are software programs that can access certain features or information from other systems, and then transmit them to other systems or applications. In this case, this type of API can help you determine whether a phone number is valid or not, and make your job easier as a developer.
