In-store using merchant callback QR

There is an issue that the test app requires you to go back to the home screen after scanning the QR. There, you will see the payment request when it is initiated. This is not an issue in production.

Before implementing this flow, please see the recommended in-store payments flow.

In this flow, a user pays by scanning a QR with their Vipps or MobilePay app. The merchant gets their ID and sends a payment request to them through the app.

Prerequisites

Merchant callback QR

Generate a merchant callback QR code.

How to create a merchant callback QR code

The QR code contains an ID that connects it to a specific POS or cash register in your store.

Here is an example HTTP PUT:

PUT:/qr/v1/merchant-callback/{merchantQrId}

{
  "locationDescription": "pos_2345",
}

Details

Step 1: The customer scans the QR

When the customer scans the QR, your system will receive a notification that the customer is ready to pay with Vipps MobilePay. The notification will contain a token the merchant can use to start a payment.

Step 2: Send the payment request

Use the token to send the customer a Create Payment request.

Detailed example

Specify "userFlow": "PUSH_MESSAGE" to send the payment to the user's app.

You may attach the receipt at this time.

Specify "customerInteraction": "CUSTOMER_PRESENT".

Here is an example HTTP POST:

POST:/epayment/v1/payments

{
  "amount": {
    "value": 10000,
    "currency": "NOK"
  },
  "paymentMethod": {
    "type": "WALLET"
  },
  "customer": {
    "token": "insert customerToken here"
  },
  "receipt":{
    "orderLines": [
      {
        "name": "socks",
        "id": "line_item_1",
        "totalAmount": 10000,
        "totalAmountExcludingTax": 8000,
        "totalTaxAmount": 2000,
        "taxPercentage": 25,
        "unitInfo": {
          "unitPrice": 4000,
          "quantity": "2",
          "quantityUnit": "PCS"
        },
      },
    ],
    "bottomLine": {
      "currency": "NOK",
      "posId": "pos_122",
      "receiptNumber": "0527013501"
    },
  },
  "reference": 2486791679658155992,
  "userFlow": "PUSH_MESSAGE",
  "returnUrl": "http://example.com/redirect?reference=2486791679658155992",
  "paymentDescription": "Purchase of socks"
}

Step 3: The customer authorizes the payment

The payment request will appear in the customer's Vipps or MobilePay app, where they can select to pay or cancel.

To get confirmation that payment was approved, monitor your webhooks.

What are webhooks?

When changes happen to your payment request, events are triggered (for example: Authorized, Terminated, Aborted, Cancelled, Expired, and many more).

You can register to receive these events, which is useful for programming an appropriate and quick response.

The webhook will send a message to your web server at the URL you specify.

See the Webhooks API guide for more details.

Once the payment is approved, update the status in your system.

Step 4: Capture the payment

Capture the payment and confirm that it was successful.

Detailed example

POST:/epayment/v1/payments/{reference}/capture

With body:

{
  "modificationAmount": {
    "value": 10000,
    "currency": "NOK"
  }
}
