In Shopify, open Apps > Vizup, choose a video in the Video Library, click Tag Product, select one or more products from your Shopify catalog, and save. The saved product tags appear with the video when it is published in a Vizup storefront widget.
These are Vizup video tags on your Shopify storefront, not native Instagram product tags. For Meta eligibility, Instagram Shopping, and product tags in Instagram posts or Stories, follow the current Instagram Shopping guide.
