# Recurring PSP API

The Recurring API is open to PSPs and has full card passthrough functionality. PSPs utilizing the API get access to all the features of the API, and can do card acquiring themselves after receiving card details in a callback.

## Currency support

There are no platform-level currency restrictions for card passthrough -- PSPs can process recurring payments in any currency supported by the Recurring API.

The currencies available to your PSP are determined by your commercial agreement with Vipps MobilePay. New PSPs signing an agreement for Recurring card passthrough will have access to all currencies and cross-border payments. Contact your PSP Partner Manager if you have questions about your agreement.

## Getting access

To get access to card passthrough for PSPs, contact your PSP Partner Manager. They will guide you through the commercial and technical onboarding process and provide your PSP ID.

When making API requests, include the `Merchant-Serial-Number` header for the merchant/sales unit you are operating on behalf of. Use the merchant's MSN, not the PSP's own MSN.
