If your store runs on Shopify, WooCommerce, BigCommerce, Magento, or OpenCart — no. The plugin handles catalog sync, event tracking, and widget placement. WooCommerce users install CartAmplify for WooCommerce directly from the WordPress.org plugin directory; the other platforms have equivalent one-click installs. You’ll go through onboarding in the dashboard and pick widget placements from dropdowns. If you’re on a custom platform or a headless storefront, you’ll need a developer to handle the API integration.
