# MobilePay Online

**Maintenance mode**

This API is in maintenance mode: we continue to support and maintain it, and no end of life date is planned.
New PSP functionality is added to the [ePayment API](https://developer.vippsmobilepay.com/docs/APIs/psp-epayment-api/README.md), so we recommend it for
new integrations.

This API is only available in the Danish and Finnish markets.

*MobilePay Online* is designed exclusively for Payment Service Providers (PSPs) to enable smooth MobilePay payments.

With PSP integrations, all settlements are managed by the PSP.
The API handles everything from initiating payments to updating their status--and even
includes merchant onboarding to make things easier.
