Showing coupons at checkout
Follow the guide below to set this up. Once done, the coupons a customer holds also appear on the checkout page of your online store.
Setup guide: Showing the coupon list at checkout
Because of how Shopify works, this is only possible for merchants on Shopify Plus.
Showing coupons on the account page
Appify can build the account page in two ways, so the setup differs.
If it is built natively
With a native build, only the checkout page can show the list, and only on Shopify Plus.
Load Discount Deck from the checkout page editor.
Steps are here.
If it is built as a webview
A webview renders the same page as Shopify’s account page, so configure it the same way as the online store.
