App Payments to ePayment
Migrating from MobilePay App Payments to Vipps MobilePay ePayment is a seamless process due to the similarities between the two APIs. This guide provides a detailed comparison between the MobilePay App Payments facade API and the Vipps MobilePay ePayment API, highlighting the key differences and mapping the endpoints to ensure a smooth transition.
Before you begin, make sure to review our migration readiness guide to prepare for the switch.
Explore the new features available in the ePayment API to enhance your solution and provide more value to your customers.
Key differences between App Payments and ePayment
Authentication
Instead of API keys or OpenId, the ePayment API uses an Access Token solution.
Reference
The reference (also called orderId) must be unique for the sales unit Merchant Serial Number (MSN) (i.e., the ID of the sales unit).
The reference doesn't need to be globally unique, so several MSNs may use the same reference, as long as it's unique for each sales unit.
The reference is case-sensitive. We strongly recommend using a format like acme-shop-123-order123abc, instead of just 123456.
For more details, please visit our 'Recommendations for payment identifier' page.
Description
The paymentDescription can no longer exceed 100 characters.
If a payment description exceeds this length, the request will fail with 400 Bad Request and reason:
"The field PaymentDescription must be a string with a minimum length of 3 and a maximum length of 100."
Webhooks
Webhooks have more and different events. Read more in the Webhooks section. The mechanics for verifying webhooks has changed. Find all details in the Webhook authentication section.

New features
Now that you are moving to the ePayment solution, you can take advantage of some new features to improve your solution and enhance user experience.
Freestanding card payments
The ePayment API supports freestanding card payments, where any user can pay with a card without using the app. This allows merchants to accept payments from customers in countries where the Vipps / MobilePay app is not yet available.
Receipt directly in the app
Need to show an invoice or don't want paper receipts? The ePayment API comes with pre-built order management API integration, making it easy to supply order information at payment creation. You can add order lines to attach a receipt shown to the user in the app. Alternatively, supply a URL to show the user an invoice or similar. All are accessible before the user accepts the payment.
User data
Remove the hassle of the user inputting their data manually. The ePayment API lets merchants ask for the user's profile information (such as phone number or email address) as part of the payment flow with profile sharing.
Login
Need an easy way to log your users in to your app? You don't have to stick with the ePayment API, you are free to use all our APIs including Login that can be used to retrieve user data or as a login option.
Merchant and sales unit data through the API
There is no need to go through the portal to fetch you merchant serial number when you use the Management API. This is especially relevant for partners, as it can also be used to onboard and fetch information about their merchants.
Cross-border payments
The ePayment API enables merchants to provide payment services to users across Vipps MobilePay market areas, such as enabling a Danish merchant to offer convenient Vipps MobilePay wallet payments to customers in Norway, Finland, or Sweden.
For details, see Offering Vipps MobilePay in the Nordics.
