An additional .METADATA suffixed JSON file can be optionally included with your Audience Export, which help to gain more context regarding the exported audience.

Please note the partner and match objects will only be present when exporting a Matched Audience
How to Use It?
In the UI, simply toggle the checkbox to have a metadata file included during the export. If you do not wish to export the metadata file, you can uncheck this box.
