Incorporating this possibility, I think it would allow hundreds of programmers to implement Perfit overnight without having to wait for the native solution on their side, it would even lower development costs and on this side we wouldn't have to wait for a native solution to come out.

Another option is that the catalog can be generated from the Google Merchant Center XML feed or from the CSV for importing the meta catalog (ex Instagram Shopping). Many systems already generate any of these feeds, or they would be easy for a developer to implement. Thank you!
