Auto-applying coupons at checkout works differently depending on coupon type (e.g., Postscript-generated coupons vs. Shopify-generated coupons) and tool (e.g., popups, keywords, etc.). We discuss these nuances below.
Auto-Applying Postscript Coupons at Checkout
Keyword and Popup Replies
When using Postscript coupons in your popup replies, select the Auto-apply coupon at checkout checkbox below your welcome message.
Auto-Applying Shopify Coupons at Checkout
When using Shopify coupons in your campaigns or other messages, be sure to include the Discount Link merge tag. When this merge tag is included in your messages, the Shopify-generated discount code will automatically apply at checkout.
