Managing your website
Which Shopify link should I use for a Buy now button?
Use a Shopify cart permalink that includes the product variant and quantity, not the shop homepage or a general product page. Copy the link using your store's permanent myshopify.com address and paste it into the gallery item's Buy now field.
BadPigeon currently accepts standard myshopify.com cart permalinks only. A custom storefront domain cannot be confirmed safely from the address alone, so custom-domain Shopify links are not yet accepted. The menu names and available features in Shopify can vary by plan and country.
