Checkout API checklist

The Checkout API is composed of several Vipps MobilePay services, while transaction operations are to be performed on the ePayment API. For examples of requests and responses, see the Checkout API guide and ePayment API guide.

Checklist for full integration

Integrate all the Checkout API endpoints

EndpointComment

When the checklist is completed, notify Vipps MobilePay Integration Service at developer@vippsmobilepay.com. Include examples from the test environment, pilot customer info, and a description of the implemented solution.

We will verify the integration and contact you. After the checklist is approved, we'll send you the information you need to get started.

Quality assurance

ActionComment
Handle callbacksCorrectly handle callbacks from Vipps MobilePay, both for successful and unsuccessful payments. See the API documentation for how callback URLs are built, make test calls to make sure you handle the POST requests correctly. We do not have capacity to manually do this for you.
Handle errorsMake sure to log and handle all errors. All integrations should display errors in a way that the users (customers and merchant employees/administrators) can see and understand them.
Include HTTP headersSend the HTTP headers in all API requests for better tracking and troubleshooting (mandatory for partners and platforms, who must send these headers as part of the checklist approval).
Add information to the payment historyWe recommend using the Order Management API to add receipts and/or images to the payment history. This is a great benefit for the end user experience. It is also mandatory for merchants using Content monitoring.

Avoid integration pitfalls

ActionComment
Send useful referenceFollow our reference recommendations.
Poll for payment detailsThe Merchant must not rely on fallback or callback alone, and must poll Payments Details GET:/epayment/v1/{reference} or Session Details GET:/checkout/v3/{reference} as documented (this is part of the first item in this checklist, but it's still a common error). For pure payment status polling the ePayment API is recommended. Follow our polling recommendations.
Handle redirectsThe merchant must handle that the fallback URL is opened in the default browser on the phone, and not in a specific browser, in a specific tab, in an embedded browser, requiring a session token, etc. Follow our recommendations regarding handling redirects.
Follow design guidelinesThe branding must be according to the design guidelines.
Educate customer supportMake sure your customer service, etc. has all the tools and information they need available in your system, through the APIs listed in the first item in this checklist, and that they do not need to visit portal.vippsmobilepay.com for normal work.
