Overview
The node "Evolution API" allows interaction with the Evolution API service, specifically supporting various resources and operations. For the provided resource "Mensagem" and operation "Enviar Audio," this node sends an audio message to a specified recipient via the Evolution API. This is useful in scenarios where automated audio notifications, voice messages, or audio alerts need to be sent programmatically, such as customer support callbacks, appointment reminders, or marketing campaigns.

| Nome Da Instância | The name of the instance that will send the audio message. |
| Número Do Destinatário | The phone number or identifier of the recipient who will receive the audio message. |
| Audio | The audio content to send, provided as a URL or base64-encoded string. |
| Opções (Delay) | Optional delay in milliseconds before the message is sent; default is 1200 ms (1.2 seconds). |
Output
The node outputs a JSON array containing the response from the Evolution API after attempting to send the audio message. The exact structure depends on the API response but typically includes confirmation details such as message ID, status, timestamps, or error information if sending failed.
No binary data output is indicated for this operation.
