Fetch expired and redeemed gift cards

The Zettle Gift Card API is used to programmatically fetch details for a gift card. It's usually used together with the Purchase API to provide additional purchasing information. The gift card data can be used for sales reporting, bookkeeping, and accounting integrations.

To get gift card statuses and amount values, you first use the Purchase API to fetch purchase history and gift card UUIDs. Then you use the Gift Card API to access gift card details.

See the following for steps to retrieve gift card details for expired and redeemed gift cards.

Prerequisites

  • Authorisation setup with a valid authorisation token and the access scope READ:PURCHASE.

Step 1: Fetch purchase history

Fetch and store the purchase history at regular intervals. It's recommended to retrieve the data during low-peak traffic hours, for example at midnight. In the request parameters, set the startDate to the most recent time of the data retrieval.

1
GET /purchases/v2?startDate={startDate}

Example: This request fetches purchase information from 19 November 2020 and onwards.

1
GET /purchases/v2/?startDate=2020-11-19

Step 2: Fetch gift card UUIDs

In the stored purchase history, retrieve the giftcardUuid for all purchases made by gift cards. Iterate through the product list for each purchase and search for the GIFTCARD product type.

Tip: In the response, you can search through all product lists in all purchases using a JSONPath $.purchases[*].products[?(@type==GIFTCARD)].giftcardUuid.

Example: In the stored purchase information response, search for the GIFTCARD product type.

Step 3: Access gift card details

  1. For Uuid, use the retrieved giftcardUuid from the previous step to access gift card details.

Example: This request fetches the details for the gift card with giftcardUuid 5c84a1a6-96d0-11eb-b3d5-7961f4378b1d.

1
GET /organizations/self/giftcards/external/5c84a1a6-96d0-11eb-b3d5-7961f4378b1d

Response: Since the values for initial and remaining amounts are the same (5000), no redemptions have been done.

1
{
2
    "uuid": "5c84a1a6-96d0-11eb-b3d5-7961f4378b1d",
3
    "created": "2021-04-06",
4
    "validTo": "2023-04-06",
5
    "initialAmount": 5000,
6
    "remainingAmount": 5000
7
}
  1. Repeat request in 1 to access details for all fetched gift cards.

Bookkeeping of expired and redeemed gift cards

As a general rule, the value of expired gift cards and the redemption of gift cards should be accounted as revenue. See Selling gift cards.
