Overview

This node interacts with the Z-API service to validate multiple phone numbers in batch for the Contact resource. It is useful for scenarios where users need to verify the validity of several WhatsApp phone numbers at once, such as cleaning contact lists or preparing numbers for messaging campaigns.

Use Case Examples

1. Validate a list of phone numbers separated by commas to check which are valid WhatsApp contacts before sending messages.
2. Batch validate phone numbers imported from a CRM to ensure they are active on WhatsApp.

Properties

Output

JSON

• validationResults - An array or object containing the validation results for each phone number provided, indicating whether each number is valid or not.

Dependencies

• Requires an API key credential for Z-API to authenticate requests to the WhatsApp validation service.

Troubleshooting

• If the node returns an error related to authentication, ensure the Z-API credential is correctly configured and valid.
• If the validation results are empty or incomplete, verify that the phone numbers are correctly formatted and separated by commas.
• Network or API errors may occur if the Z-API service is down or unreachable; retry later or check service status.
