On the next page, you can remove the existing coupon if you want to remove it. If you want to apply a new coupon, simply select a new coupon from the dropdown and apply.

Using APIs:

To update an existing coupon via Chargebee APIs, you can use the Update subscription API call and pass the new coupon ID with the parameter "coupon".

To remove coupons, you can use the Remove Coupons API call and list the coupons to remove with the parameter coupon_ids. If the parameter coupon_ids is not specified, all coupons associated with the subscription will be removed.
