> **Description:** Details about API and platform updates for May 2024, including new features, improvements, and important changes to Vipps services.

# Technical update May 2024

## Button designer

You can now use our
[button designer](https://developer.vippsmobilepay.com/docs/knowledge-base/buttons.md)
to create the best and most effective Vipps and MobilePay buttons for your website.

Bonus: Since the button details are automatically fetched from us,
the buttons on your website will always be up-to-date.

## Management API and prefill: Get the sales unit details

When using
[prefill](https://developer.vippsmobilepay.com/docs/APIs/management-api/management-api-guide.md#prefill-a-product-order)
to fill out the product order form for merchants, it is now possible to
[get the MSN of the sales unit](https://developer.vippsmobilepay.com/docs/APIs/management-api/management-api-guide.md#get-information-about-a-product-order)
that the product order resulted in.

The status of the prefill job will be `COMPLETED`, and the response from
`GET:/management/v1/product-orders/{prefilledProductOrderId}/details`
will contain this:

```json
"salesUnit":{
   "msn":123456,
   "name":"ACME Fantastic Fitness"
}
```

See:
[Get information about a product order](https://developer.vippsmobilepay.com/docs/APIs/management-api/management-api-guide.md#get-information-about-a-product-order).

## Login API: See the number of active users on portal.vippsmobilepay.com

Merchants can now see the number of active Login users on the sales unit details page on the
[business portal](https://portal.vippsmobilepay.com).

## Danish and Finnish support in the test environment

We have worked hard and the first version of Danish and Finnish support in the test environment is ready!
The app is still orange with the Vipps logo, but you can now use the DKK and EUR currencies,
and create both Danish and Finnish test merchants and users.

See [Test environment](https://developer.vippsmobilepay.com/docs/knowledge-base/test-environment.md) for more.

## Enhance the ePayment payment screen with a link

It is already possible to
[add order details](https://developer.vippsmobilepay.com/docs/APIs/order-management-api/order-management-api-guide.md#adding-order-details)
when initiating an ePayment payment.

Now, you can also add a link to the payment, enabling users to see this before they pay.
This can be a link to an invoice or other documentation, whatever you like. Use our
[pre-built order management feature](https://developer.vippsmobilepay.com/docs/APIs/epayment-api/api-guide/features/pre-built-order-management-api-integration.md)
to enhance the user experience with e-payments.
