# Applying And Removing Discounts There are two options for applying a discount code: 1. During initial cart creation 2. To a cart that already exists ### Apply Discount Code at Cart Creation During cart creation by providing a list of `codes` and `merchant_ids` Add discounts to cart creation [request](/api-reference/orders-and-checkout/carts/create-cart.md): {% hint style="warning" %} Merchant ids must match with the merchant id on one of the provided SKUs otherwise they will be ignored. {% endhint %} ```json { "base_currency": "USD", "wallet_based_checkout": false, "skus": [ { "sku_id": 99638, "quantity": 1 } ], "discounts": [ { "code": "20p_off", "merchant_id": 22 } ] } ``` ### Apply Discount Code to Existing Cart Add discount to existing cart by providing a single `code` and `merchant_id` in the [dedicated endpoint](/api-reference/orders-and-checkout/cart-shipping/set-shipping-methods.md) {% hint style="warning" %} Merchant ids must match with existing sku merchant ids in cart otherwise it\ will be ignored. {% endhint %} ```json { "code": "20p_off", "merchant_id": 22 } ``` Both endpoints will return the entire cart with the discounts applied to correct bags.

It means that when a cart\ with discounts is submitted, only `APPLIED` discounts are considered, all\ other discount statuses and errors are removed from cart. {% endhint %} ## Removing Discounts Removing discounts is simple. Discounts can be removed from bags through the \[DELETE] `/checkout/cart/:cart_id/discounts/:discount_id` endpoint. The cart will be returned with current status without the previously applied discount. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
