# Headless Shopify Compatibility

People sometimes ask, "Does Regios Discounts work with Shopify Headless"?
* Discounts you create in our app will work in the Shopify checkout.
* Once applied to the cart, the discounts should be visible in the Storefront API.
* The "discount on product page" (DOPP) feature requires Online Store 2.0. Therefore, you cannot display discounts on product pages in headless sites.
* Our Auto Add to Cart feature doesn't work on headless setups because  our app requires the Shopify Online Store to use the app embeds, which means it is not compatible with headless setups.
