Do you want to know how an API might help your company? Then continue reading because we’ll tell you everything you need to know about it and much more!

WhatsApp has more than 1.5 billion users worldwide, making it the most popular messaging program. People have accepted it as the finest way to communicate with family and friends. But what about companies? 

WhatsApp is a powerful marketing tool for organizations, but it is not as simple as creating an account and sending messages. To reach your target audience successfully, you must first authenticate your phone number and then open a WhatsApp Business account if you are a small business or an agency. This is where a Number Checker API can be useful.

WhatsApp Business accounts differ from personal accounts in that they have access to additional capabilities that enable businesses to connect with their consumers and new clients. These capabilities include WhatsApp Chatbots, WhatsApp Call functionality, and WhatsApp Business pages.

To use these capabilities, a WhatsApp Business account must be linked to a phone number. This means that WhatsApp will verify the number by sending an SMS or contacting it to check that it is active and belongs to a real person.

However, not all phone numbers are valid, so double-check that your potential clients’ phone numbers are correct before sending them messages or making calls.

Let’s Introduce The WhatsApp Number Checker API

This is the best tool for finding out the phone number of a WhatsApp contact. Simply typing a number into this tool will tell you whether it is valid or not. You will also be given information regarding its geographical location. This information is essential for marketing since it allows you to focus on locations where your target audience lives rather than wasting time and money contacting invalid numbers.

Before you may access the API endpoint, you must first create an account and obtain an API key. In the second phase, the WhatsApp Number Checker API will require access to your phone number database. You’ll be able to see it and ask questions about it online.

To demonstrate your humanity, check the box next to “I am not a robot” as the third step. After entering the phone number to be validated as well as the bearer token obtained in the previous step, click “test endpoint” to send an API endpoint request. Not to mention that you’ll receive a response with details on the phone number you requested, such as whether it’s genuine and from which country.

You can use the endpoint to determine whether WhatsApp has access to the phone number. If you submit a phone number into this API and get the following result, you can use it to see if the phone number is real and if WhatsApp has a record of it:

The phone number should be entered without the plus sign and with the right country code in this case: 5491168989605. You can use the endpoint to determine whether WhatsApp has access to the phone number. 

This API can instantly tell you which of your contacts’ phone numbers are still active and which have been disconnected. You can also use this tool to see whether your own phone numbers are still active. You can also see whether the client picks up or not by sending an SMS or making a voice call to one of these validated numbers. If they do, you know their contact information is current and active; if they don’t, you know you need to update it in your database.

It instantly validates the correctness of any number in your database. Check your phone numbers to determine which ones are still in use before starting an SMS campaign. Check the phone numbers in your lead database to ensure they are valid before calling.

All of this can be done automatically with this type of software, eliminating the need to manually enter each figure and wait for the results. This is why, if you want to speed up the process and get correct results, we recommend using a trusted API like this User Authentication API.
