> **Description:** Create flexible payment solutions for both online and in-store purchases using Vipps, MobilePay, and card payments through a single, unified API.

# ePayment API

The ePayment API makes it simple for your customers to pay--online or in-store. With support for multiple payment methods (Vipps, MobilePay, and cards), you can offer a smooth, flexible checkout experience that fits your needs.

Integration is straightforward, and you'll have tools to personalize payment flows, track transactions, and ensure security.

Order *Payment integration* on [vippsmobilepay.com](https://vippsmobilepay.com/en-NO/online/payment-integration).

*Express is our fastest and most seamless payment experience yet.*

It allows customers to:

- Choose from multiple shipping options directly within the Vipps or MobilePay app.
- Consent to sharing their contact and delivery details with the merchant.
- Review the total amount, including shipping, before confirming payment.

This streamlined flow makes checkout quicker, simpler, and more user-friendly for your customers -- all without leaving the app.
