It is useful for scenarios where users need to retrieve media files sent or received in WhatsApp conversations, such as images, audio, or documents. For example, it can be used to automatically download and process audio files for transcription or save media files to a public URL for sharing.
Use Case Examples
- Downloading an audio file from a WhatsApp message and converting it to MP3 format.
- Retrieving a document from a cited message in a WhatsApp conversation.
- Saving a media file to a public URL and optionally encoding it in base64 for further processing.
