Feeds

Feeds are used to export product data to be imported into other services e.g. Google Ads merchant center.
Google Merchant Center allows feeds to be exported via XML or via their content API.

Getting Feeds

Methods to generate feeds are usually not installed by default on self hosted systems and generally require some form of plugin to be installed.
