Overview
This node interacts with the Green API to handle WhatsApp voice messages. It supports two main operations: retrieving the download URL for a voice message and downloading the voice message file itself. This is useful for automating workflows that involve processing or storing WhatsApp voice messages, such as archiving messages, analyzing audio content, or integrating voice messages into other systems.
Use Case Examples
- Automatically fetch the download URL of a WhatsApp voice message for further processing.
- Download a WhatsApp voice message and save it as binary data within the workflow for storage or playback.
