Yes, Connect My Sales can automatically sync your products from your store to Infusionsoft. To accomplish this, you should create a test order in your store and add all of the products to the order, then mark that order as "Paid".
When Connect My Sales syncs the order, it will automatically create any products not already in Infusionsoft. Additionally, product tags will be created in Infusionsoft for each of the products synced. The product tags can be used in Campaign Builder to create tag-applied goals for specific product purchases.
Note that Connect My Sales uses the product SKU to determine whether a product exists in Infusionsoft. For this reason, it is recommend that you add SKUs to each of your products in your e-commerce store.
