Overview

This node interacts with the Z-API service to validate WhatsApp phone numbers. It is useful for scenarios where you need to verify if a phone number is registered on WhatsApp before sending messages or adding contacts. For example, it can be used in customer support workflows to ensure contact numbers are valid WhatsApp users or in marketing automation to filter out invalid numbers.

Use Case Examples

1. Validate a phone number before sending a WhatsApp message to avoid errors.
2. Check if a contact's phone number is registered on WhatsApp before adding them to a group.
