# Payment integration

The *Payment integration* product offers APIs to communicate with Vipps MobilePay regarding online payments.

In both online and in-store interfaces, when a user selects to pay with Vipps or MobilePay, this request is sent to Vipps MobilePay through one of these APIs:

* [ePayment API](https://developer.vippsmobilepay.com/docs/APIs/epayment-api/README.md) - Offers services to both Vipps  and MobilePay  in Denmark, Finland, Norway, and Sweden.
* [eCom API](https://developer.vippsmobilepay.com/docs/APIs/ecom-api/README.md) *(legacy API in maintenance mode)* - Offers services to Vipps customers in Norway.
