WhatsApp Phone Number Checker

This script is developed to check the existence of phone numbers in WhatsApp. It analyzes the numbers specified in the file and classifies them into existing numbers in WhatsApp and non-existing ones.

Check any numbers from any country. Determine which phone numbers are active and which cannot receive Whatsapp messages. Optimize your resources and save time and money.

This tool was created using our public API that you can access too with your Whapi.Cloud account. Getting Started with our API: https://support.whapi.cloud/help-desk/getting-started/getting-started

How to use

Preparation

Make sure you have Node.js installed.
Clone the repository or download the source files of the script.

Customization

open the phones.json file.
In the check_phones array, add the phone numbers you want to check. For example:
```
{
  "`check_phones`: [ "number1", "number2".]
}
```

Requirements

In the file config.json you need to insert the token from your personal account Whapi.Cloud, as well as the number you want to check. It also shows the limits we recommend to use. daily_limit is how many checks are left, and refreshed_limit is how much of the limit is set on refresh.

The delay argument determines the frequency of checks. And checks_per_delay is responsible for the number of numbers that will be checked during the check.

{
  "token":"YOUR-TOKEN",  // Whapi.Cloud channel token.
  "refreshed_limit": 1000, // Maximum number of checks per day.
  
  "last_limit_refresh": 0, // Date of last update of limits. (Filled automatically).
  "daily_limit":0 // Remaining number of checks per day (Filled automatically).
  
  "delay": 10000, // Pause between checks of the number packet
  "checks_per_delay": 5 // Amount of numbers to be checked by one packet
  
  // In this case, 5 numbers will be checked every 10 seconds, but a maximum of 1000 numbers per day.
}

Running the script

Open a terminal or command prompt in the folder with the script. Run the following commands to install the necessary dependencies and compile the script: npm i

Run the script with the command: npm run start

Result

When the script finishes, you will get two files with results: invalid.csv and valid.csv, where numbers will be filtered accordingly.

The invalid.csv file will contain numbers that do not have WhatsApp.
The valid.csv file will contain numbers that have WhatsApp.
The unlimited.csv file may appear if there are numbers left that are outside the daily limit you have set in the settings. This will allow you to continue working on checking numbers using this file.
