Hi @OliviaC, 

Thanks for sharing your question with us concerning coupons, happy to help! 

Do you mind sharing what your ultimate goal is when changing your coupon setting in Shopify and wanting them to reflect back in Klaviyo? Since Shopfiy has more coupons setting and variations compared to Klaviyo, for instance we only support one-time purchases with coupons and cannot apply dynamic coupons to subscription items, any changes you want to make to your coupons in Klaviyo will need to be done manually. Changes in Shopify via your coupons won’t be reflected in Klaviyo automatically. 

Thanks for participating in the Community!

Hey Taylor, thanks for your reply! I was hoping to get a dynamic coupon for a specific subscription product but it looks like this wont work this time!
