Adding a gift card or coupon

How to redeem a gift card or coupon by entering a code
Problem
You have a pending order and you want to give your customer the possibility to add a gift card or coupon code to the order so that they get the associated discount.

Solution
To add a gift card or coupon code to an order, send a PATCH request to the /api/orders/:id endpoint, setting the gift_card_or_coupon_code attribute to the desired value. If an active gift card or coupon code matches that value — with at least the first 8 digits — the order amounts are updated according to the associated gift card balance or coupon discount.
In the unlikely event that both a gift card and a coupon code match the same code, the gift card takes precedence.
Example
Request
Response
The following request adds the gift card identified by the "GIFT1234-ABC" code to the order identified by the "NgojhKoyYN" ID:
curl -g -X PATCH \
  'https://yourdomain.commercelayer.io/api/orders/NgojhKoyYN' \
  -H 'Authorization: Bearer your-access-token' \
  -H 'Accept: application/vnd.api+json' \
  -H 'Content-Type: application/vnd.api+json' \
  -d '{
    "data": {
      "type": "orders",
      "id": "NgojhKoyYN",
      "attributes": {
        "gift_card_or_coupon_code": "GIFT1234-ABC"
      }
    }
  }'
On success, the API responds with a 200 OK status code, returning the updated order object:

Additional notes
Separating the gift card and coupon fields
Using the gift_card_or_coupon_code attribute is a convenient way of managing the most common use case, when you have just one field that can accept both types of code. In case you need to manage gift cards or coupon code fields separately, you can use the gift_card_code or the coupon_code attributes instead.
Removing a gift card or coupon code
In case you want to remove a gift card or coupon code from the order — resetting any applied discount — you need to send a blank value to either the gift_card_code or coupon_code field.
