Code matching and wildcards
AIOD’s helper text: “Codes match regardless of case. Use * to match any characters: INF-* covers INF-ALICE, INF-BOB and so on.”- A code without
*must match exactly, ignoring case. *matches any characters, including none, and can appear anywhere in the code.- Spaces before or after a listed code are ignored.
- AIOD rejects only codes that Shopify allows a discount function to reject. A code Shopify marks as not rejectable stays applied.
Allow only one of these codes
AIOD’s helper text: “Keep the code the customer entered last and reject the others. Without this, every matching code is rejected.”
If Shopify marks one of the matching codes as not rejectable (for example, its discount is already applied), that code is the one kept, and every other matching code is rejected.
Use this to stop customers from stacking several codes from the same list, for example when only one influencer code should apply per order. The rule’s When To Reject Discount Codes condition must still be met.
Message shown to customers
Message shown to customers sets the text customers see at checkout when a code is rejected.- Placeholder:
This code isn't applicable with your cart. - Helper text: “Shown at checkout when a code is rejected. is replaced with the rejected codes. Leave empty to use the default.”
- Maximum length: 255 characters.
- Leave it empty to show the default message,
This code isn't applicable with your cart.
{codes} can't be combined with your bundle price. shows as INF-ALICE can't be combined with your bundle price. When several codes are rejected, {codes} lists them separated by commas, such as INF-ALICE, INF-BOB.
The message is shown in the language the merchant writes it in. It is not translated per customer language.
