Overview

This node allows sending a voice message to a specified contact via the CrunchzApp API. It is useful in scenarios where you want to automate voice communications, such as sending reminders, alerts, or personalized voice notifications to users. For example, a business could use this node to send appointment reminders as voice messages directly to customers' messaging apps.

Properties

Name Meaning
Contact Id The unique identifier of the contact to whom the voice message will be sent (format: xxx@c.us).
Audio Url The URL pointing to the voice audio file to be sent. Supported formats include .opus and similar audio types.

Output

The node outputs JSON data representing the response from the CrunchzApp API after attempting to send the voice message. This typically includes information about the success or failure of the message delivery. The node does not output binary data.

Dependencies

  • Requires an active CrunchzApp API key credential configured in n8n.
  • Depends on the CrunchzApp API endpoint https://api.crunchz.app/api.
  • The audio file must be accessible via a public URL.

Troubleshooting

  • Invalid Contact Id: If the contact ID is malformed or does not exist, the API may return an error. Ensure the contact ID follows the expected format (xxx@c.us) and corresponds to a valid user.
  • Audio URL Issues: If the audio URL is inaccessible, invalid, or points to an unsupported format, the message will fail to send. Verify that the URL is publicly reachable and the audio file is in a supported format like .opus.
  • Authentication Errors: Missing or incorrect API credentials will cause authentication failures. Confirm that the API key credential is correctly set up in n8n.
  • Network or API Downtime: Temporary network issues or CrunchzApp API downtime can cause request failures. Retry after some time or check the service status.
