# Checkout API

**Important update**

Vipps MobilePay has entered into an agreement to sell the Checkout solution to [Kustom](https://www.kustom.co/).

As part of this transition, *Vipps MobilePay Checkout* will become *Kustom Checkout*. This means the Checkout product you ordered will be delivered and developed by Kustom going forward.
If you have questions, you can check our [FAQ](https://vippsmobilepay.com/en-NO/vippsmobilepay-kustom).
