Open Google Merchant Center
Go to merchants.google.com and sign in with the Google account linked to your Merchant Center. Create a Merchant Center account first if you do not have one yet.
Go to Settings → Data sources
From the left sidebar, open Settings and click Data sources. Check whether an old source already exists — for example Shopify App API, Shopify app, or another Merchant API source. If you are replacing it, use the ⋮ menu on the right side of that source.
Click Edit countries on the old source
After clicking the ⋮ menu, select Edit countries. This opens the country assignment popup for that existing source.
Deselect all countries and save
In the Add more countries popup, deselect All countries and any selected countries, then click Save. This stops the old source from serving products in those countries.
Click Add product source
Return to the Provided by you section and click Add product source. This is where you add the new Feedfly Google feed.
Add products from file using your Feedfly URL
Select Add products from a file, choose Enter a link to your file, paste the Google feed URL from Feedfly → Feeds, then click Continue. Set your fetch schedule on the next screens if prompted.
