Overview
The node integrates with the NotificaMe Hub API to send WhatsApp audio messages. Specifically, the "Enviar Áudio" operation under the "WhatsApp" resource allows users to send an audio file (such as MP3 or OGG) to a specified recipient's phone number via WhatsApp.
This node is beneficial in scenarios where automated voice or audio notifications are needed, such as sending alerts, reminders, voice greetings, or promotional audio clips directly to customers' WhatsApp accounts.
Practical example:
A business can use this node to automatically send a recorded appointment reminder or a promotional jingle to clients who have opted in to receive WhatsApp communications.
Properties
| Name | Meaning |
|---|---|
| Token Do Canal | The authentication token for the WhatsApp channel, required to authorize the API request. |
| Número Do Destinatário | The recipient's phone number in international format (e.g., 5511999999999). |
| URL Do Áudio | Publicly accessible URL of the audio file to be sent (supported formats: MP3, OGG). |
Output
The node outputs JSON data representing the response from the NotificaMe Hub API after attempting to send the audio message. This typically includes status information about the message delivery, such as success confirmation or error details.
There is no indication that the node outputs binary data; it primarily handles JSON responses related to message sending status.
Dependencies
- Requires an active internet connection to communicate with the NotificaMe Hub API endpoint at
https://hub.notificame.com.br/v1. - Needs a valid WhatsApp channel token (API key or similar credential) to authenticate requests.
- The audio file must be hosted at a publicly accessible URL (no authentication required to access the file).
- No additional environment variables or n8n-specific configurations beyond providing the channel token credential.
Troubleshooting
Common issues:
- Invalid or expired channel token will cause authentication failures.
- Incorrectly formatted recipient number (not in international format) may result in message delivery errors.
- Audio URL not publicly accessible or invalid format may cause the API to reject the message.
- Network connectivity problems can prevent communication with the NotificaMe Hub API.
Error messages and resolutions:
- Authentication failed: Verify the channel token is correct and has not expired.
- Invalid recipient number: Ensure the number includes country code without spaces or special characters.
- Audio file not found or unsupported format: Confirm the URL is reachable and points to a supported audio file type (MP3 or OGG).
- API request timeout or network error: Check internet connection and API service status.
