What's the difference between Attrac coupons and Shopify coupons?

When a coupon is created in Attrac, it is also mirrored on Shopify. Therefore, these coupons can be further edited or given more advanced settings on Shopify, even if they were initially created on Attrac.

So, the two are alike, and Shopify offers more advanced coupon settings. However, Attrac offers the ability to create a unique coupon code per customer for signup campaigns, a feature not available on Shopify.

In conclusion, for a master coupon (the same code for all customers), you can create it on Attrac or Shopify. But if a unique coupon type is needed, which creates a unique coupon code for each customer for signup campaigns, then you need to create this coupon on Attrac.
