Omega Feed supports two sync methods for Google Merchant Center (GMC):

• API Sync — connect directly to Google Merchant Center (products are pushed via the Content API)
• XML Feed — generate a feed URL for manual submission to Google Merchant Center or other platforms

From Shopify Admin:

• Sidebar → Google Shopping

On the empty state screen ("No feeds created yet — Create a feed to sync products from Shopify to GMC"), click + Create first feed

Step 2: Choose Sync Method

Available options:

• Connect automatically (via API) — recommended for automatic catalog sync and scheduled updates

• Use a data file (XML) — generate a feed URL for manual submission to Google Merchant Center
