> **Description:** The Payment Service Provider (PSP) API enables payment processors and providers to integrate Vipps payments into their payment systems, allowing their merchants to accept Vipps payments in Norway.

# Vipps PSP API

**End of life**

This API doesn't have any set end of life yet, but is receiving critical maintenance only. Long term support for PSPs will be served by the [ePayment API](https://developer.vippsmobilepay.com/docs/APIs/psp-epayment-api/README.md). No new integrations to this API will be approved.

The Vipps PSP API is used only by Payment Service Providers (PSPs) for Vipps payments.
Settlements for PSP integrations are handled by the PSP.

Use the PSP API to initiate PSP payments, get details about PSP payments, or update their status.
In addition, you can use the PSP Merchant API to get information about merchant sales units or create new sales units.

PSPs can onboard and manage merchants through the [PSP Merchant API guide](https://developer.vippsmobilepay.com/docs/APIs/psp-merchant-api/psp-merchant-api-guide.md).
