The Discount code field appears inside the cart drawer and lets shoppers apply a code before they check out.
Discount code allows customers to enter and apply their code without leaving the cart, so they can see the savings straight away instead of waiting until checkout.
The field sits above the totals, and you can rename the placeholder, the button, and the error message.
How to enable discount code?
In the app, go to Custom Cart.
In the left sidebar, open Features → Discount code.
In the Discount code panel, click Enable.
What you can configure:
Discount code field placeholder — the hint text shown inside the empty field (default: Discount code)
Button label — the text on the apply button (default: Apply)
Error message — shown when the code is invalid or cannot be applied (default: Enter a valid discount code)
