UazAPI

Overview

This node integrates with the UazAPI service, providing extensive automation capabilities for WhatsApp through over 90 endpoints. Specifically, for the Chat resource and the Check Number operation, it allows users to verify if a given phone number is registered on WhatsApp.

This functionality is useful in scenarios such as:

• Validating contact lists before sending messages to avoid errors or bans.
• Filtering numbers to ensure only active WhatsApp users are targeted.
• Automating workflows that depend on the presence of a WhatsApp account for a number.

For example, a user can input a phone number, and the node will return whether that number exists on WhatsApp, enabling conditional logic in automation flows.

Properties

Output

The output JSON contains the response from the UazAPI endpoint that checks the WhatsApp registration status of the provided number. Typically, this includes information indicating whether the number is registered on WhatsApp.

Example output structure (simplified):

{
  "numbers": [
    {
      "number": "5511999999999",
      "exists": true,
      "status": "valid"
    }
  ]
}

• numbers: An array containing objects for each checked number.
• number: The phone number checked.
• exists: Boolean indicating if the number is registered on WhatsApp.
• status: Additional status info (may vary).

No binary data is output by this operation.

Dependencies

• Requires an API key credential for authenticating with the UazAPI service.
• The node expects the base URL of the UazAPI to be configured in the credentials.
• Network access to the UazAPI endpoints is necessary.

Troubleshooting

• Common issues:

  • Invalid or missing API credentials will cause authentication failures.
  • Incorrectly formatted phone numbers may lead to unexpected results or errors.
  • Network connectivity problems can prevent successful API calls.

• Error messages:

  • Authentication errors typically indicate invalid or expired API keys; verify and update credentials.
  • Validation errors may occur if the phone number format is incorrect; ensure the number includes the country code without "+".
  • API rate limits or service downtime may result in HTTP errors; retry after some time or check service status.
