Add a coupon code via a cart link

How to apply a coupon code automatically by including it in a cart link, without the customer entering it manually.

You can apply a coupon code automatically by including it as a parameter in a cart link. This is useful for promotional links, email campaigns, or affiliate codes where you want the discount applied without the customer having to enter it manually.

Steps

Add the coupon parameter to any cart link:

https://YOURSTORE.foxycart.com/cart?coupon=DISCOUNT10

To apply a coupon without adding a product, combine with cart=view:

https://YOURSTORE.foxycart.com/cart?cart=view&coupon=DISCOUNT10

To apply multiple coupon codes at once, separate them with a comma:

https://YOURSTORE.foxycart.com/cart?coupon=DISCOUNT10,FREESHIP

Notes

  • Once applied, a coupon code remains active for the life of the session or until removed.

  • If an invalid or duplicate code is added, an error may display on the cart.

  • Do not sign the coupon value if using link and form validation.

  • For a full list of cart parameters, see Cart parameters reference.
