ePayment PSP API checklist

Use this checklist to ensure your ePayment PSP API implementation is complete and production-ready. It covers the key endpoints, quality assurance steps and pitfalls — from payments to captures, refunds, and error handling.

From test to production

1. Complete your testing of the ePayment PSP API. Use the list below to ensure you cover all areas of the integration before you submit the checklist.

2. Send your filled out checklist to us at developer@vippsmobilepay.com. Use this editable PDF to fill out and submit. Request examples in the checklist must be no more than 1 month old at the time you submit the checklist. Together with the checklist, please include a video of your payment flow and a short description of your solution.

3. We will verify your integration and get back to you as soon as possible, so you can continue with the process to go live.

Endpoints to integrate

It is important that you integrate all the ePayment API endpoints.

Create a payment with Express Optional feature	POST /epayment/v1/payments
Create a payment with Profile sharing Optional feature	POST /epayment/v1/payments
Create a payment with Minimum user age Optional feature	POST /epayment/v1/payments
Get payment status Fetch current status of a payment.	GET /epayment/v1/payments/{reference}

Update payment status with Refund	POST /epayment/v1/payments/{reference}/refund

Quality assurance

Ensure that your implementation complies with our requirements and recommendations.

Proper logging All integrations should log error responses to be used for later reference in troubleshooting. Logs must include endpoint, headers, request body, error code and message.

Include HTTP headers Send the HTTP headers in all API requests for better tracking and troubleshooting (mandatory for partners and platforms).

Specify customer interaction For instore solutions it is required to specify the customer interaction by setting "customerInteraction": "CUSTOMER_PRESENT" on payment initiation. This is to determine that the customer is present at the time of purchase.

Payment status All payments must be updated with capture or cancel status, as well as refund if this is performed.

Merchant onboarding All merchants must be onboarded as individual merchants and not super merchants, and they must be onboarded with valid MCC. All merchants must use their own merchant/webshop name and logo. See PSP merchant for more details.

Send a useful reference ID Follow our reference recommendations to ensure that each transaction is uniquely and reliably identified across all Vipps MobilePay APIs.

Handle redirects For mobile flows the implementation must handle that the returnUrl URL is opened in the default browser on the phone. And not rely on the use of a specific browser, a specific tab, an embedded browser, or a session token. Follow our recommendations regarding handling redirects.

Appswitch If you offer your merchants to use apps, you must test a switch between MobilePay app and a merchant app.

Follow design guidelines The Vipps MobilePay branding must be according to the design guidelines.

Go live

After the checklist is approved, we will send you the information you need to get access to production. In the production environment you must complete a series of production transactions to verify your solution. We recommend that you complete the production transactions with a pilot merchant. Please contact us at developer@vippsmobilepay.com with a transaction reference for each of the following:

Purpose	Endpoint	Your reference
Respond to card data callback with RESERVE	POST /psp-makepayment
Respond to card data callback with FAIL	POST /psp-makepayment
Respond to card data callback with SOFT_DECLINE	POST /psp-makepayment
Transaction with status Capture	POST /epayment/v1/payments/{reference}/capture
Transaction with status Refund	POST /epayment/v1/payments/{reference}/cancel
Transaction with status Cancel	POST /epayment/v1/payments/{reference}/refund

We will inform you when we have verified your production test, and you can then go live with your merchants 🎉
