Overview
This node operation sends an audio message via the WARest WhatsApp REST API. It supports sending audio either as a URL/path/base64 data URI or as binary data from a specified binary property. Users can send the audio as a regular audio message or as a voice note. Additional options include sending typing/recording indicators before sending, replying to a specific message, and marking the message as forwarded. This node is useful for automating audio message delivery in WhatsApp workflows, such as sending voice notes or audio clips to contacts or groups.
Use Case Examples
- Sending an audio file from a URL to a WhatsApp contact.
- Sending a voice note using binary audio data from a previous node.
- Replying to a specific message with an audio clip and showing a typing indicator before sending.
