Hey There,
I am trying to set up a Product Feed of items that are viewed, or popular viewed items from the API (well event from the API).
What I am wondering is how do I link the event to the product catalogs? what value do I need to pass in the viewed product payload to link it to the product feed...
Can I use the existing shopify feed and pass the payload with the matching ID (and if so what is the variable needed), or do I need to send a new catalog via the API, and if so how does the catalog match with the event payload?
