  2. In the top right corner of the Hub, click on your name to access the dropdown menu.
  3. Hover over "Merchant ID" in the dropdown menu.
  4. Select the icon to copy your Merchant ID to your clipboard.

Step 2: Open the Shopify Theme Editor


Return to your Shopify Theme Editor by navigating to "Online Store > Themes > Customise."

Step 3: Update the Feefo Core Widget


  1. In the Shopify Theme Editor, access the "App embeds" menu located on the left-hand side. 
  2. Select the "Feefo Core" widget. This is where you can adjust your Feefo settings.
