Overview
This node, named "Evolution API," allows interaction with the Evolution API service. Specifically for the resource Chat and operation Obter Mídia Em Base64 (Get Media in Base64), it retrieves media content from a chat message by its ID and returns the media encoded as a Base64 string. It optionally supports converting video media to MP4 format.
Common scenarios include:
- Downloading media files sent in chat messages for further processing or storage.
- Converting received video media into MP4 format for compatibility or playback purposes.
- Integrating chat media retrieval into automated workflows, such as archiving or analysis.
Example use case:
- Automatically fetch an image or video sent in a chat conversation, convert it if needed, and upload it to cloud storage or attach it to a ticketing system.

Output
The node outputs a JSON array where each item corresponds to the result of the media retrieval operation. The key output is the media content encoded as a Base64 string within the JSON data.
If the media is a video and the conversion option is enabled, the output will contain the media converted to MP4 format, also encoded in Base64.
No binary data output is explicitly indicated; all media content is returned as Base64-encoded strings inside the JSON output.
