Add metadata

Add custom metadata to your payment transactions to facilitate tracking, reconciliation, and integration with your existing systems. We’ll store it as provided and return it in the GetPaymentResponse of GET:/epayment/v1/payments/{reference}.

This feature allows you to attach additional information to each payment, making it easier to integrate with your other systems.

Create a payment with metadata

Call the POST:/epayment/v1/payments with metadata.

For example:

curl -X POST https://apitest.vipps.no/epayment/v1/payments \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR-ACCESS-TOKEN" \
-H "Ocp-Apim-Subscription-Key: YOUR-SUBSCRIPTION-KEY" \
-H "Merchant-Serial-Number: YOUR-MSN" \
-H "Idempotency-Key: YOUR-IDEMPOTENCY-KEY" \
-H "Vipps-System-Name: acme" \
-H "Vipps-System-Version: 3.1.2" \
-H "Vipps-System-Plugin-Name: acme-webshop" \
-H "Vipps-System-Plugin-Version: 4.5.6" \
-d '{
    "metadata" : {
        "location" : "Q-Park Magasin du Nord",
        "date" : "2026-01-05 12:00 - 14:34 "
    },
    "amount": {
        "value": 15000,
        "currency": "DKK"
    },
    "paymentMethod": {
        "type": "WALLET"
    },
    "customer": {
        "phoneNumber": "4512345678"
    },
    "reference": 21203831704360461822,
    "userFlow": "PUSH_MESSAGE",
    "paymentDescription": "QPark",
    "receiptUrl":"https://example.com/link/to/my.pdf"
}'

Get payment details

When you include metadata in the Create payment request, you’ll find the same metadata returned in the GET:/epayment/v1/payments/{reference} response.

For example (truncated):

{
  "metadata" : {
        "key1" : "value1",
        "key2" : 12345
    }
}
