Overview
The node interacts with the Wazzap API to send voice messages via WhatsApp. Specifically, for the "✉️ Message" resource and the "🔊 Send Voice Message" operation, it converts a text message into a voice message and sends it to a specified recipient's phone number.
This node is useful in scenarios where automated voice notifications or alerts need to be sent through WhatsApp, such as appointment reminders, customer support callbacks, or marketing campaigns that require voice communication instead of text.
Example use cases:
- Sending a personalized voice reminder to customers about an upcoming appointment.
- Delivering urgent voice alerts to a group of users.
- Automating voice-based customer engagement messages.

https://doc.wazzap.mx/api-referenceor the actual Wazzap API endpoint.
Troubleshooting
- Unsupported operation error: If the node throws an error stating the operation is unsupported, verify that the resource and operation names are correctly set to "✉️ Message" and "🔊 Send Voice Message".
- Invalid phone number format: Ensure the recipient phone number includes the correct country code and no invalid characters.
- API authentication errors: Confirm that the API key or token credential is properly configured and has sufficient permissions.
- Message not delivered: Check delay settings; excessive delays might cause unexpected timing. Also, verify the priority number if using specific sending slots.
