Hello! If I set up local inventory within Shopify Google App, will it automatically create a local inventory feed from my online products through content api?
Or do I have to create a feed manually in Google Merchant center?
Hey Amarineelectric, you can see the integration shopify has with google in the shopify app store, it will automatically sync your inventory over to be visible to shoppers on google.
Hope this helps 
It will automatically create the feed via the content API, you will a second primary feed with local listings once enabled. It may take a few weeks to a month to get approved, so be patient when enabling this.
