All notable changes to the current API will be documented here.
To learn about API versioning, see
[API lifecycle](https://developer.vippsmobilepay.com/docs/knowledge-base/api-lifecycle.md).

Changes that affect multiple APIs are documented in the [general changelog](https://developer.vippsmobilepay.com/docs/changelog.md).

## April 2026

* v1.3.0:
  * Renamed this API from **PSP Signup API** to **PSP Merchant API**. The functionality is unchanged.
  * The `organizationNumber` field is now validated against official business registries for Nordic merchants on onboarding.
    * For Norway: the org number must be 9 digits, the merchant must be active in [Brønnøysundregistrene](https://www.brreg.no), and must be a main entity ("hovedenhet"), not a sub-entity ("underenhet").
    * For other Nordic countries: the org number, address, and related fields are validated as much as practically possible.

## February 2026

* v1.2.0:
  * Added `termsOfServiceAccepted` field to the [Create merchant](https://developer.vippsmobilepay.com/redocusaurus/psp-merchant-swagger-id.yaml) and [Update merchant](https://developer.vippsmobilepay.com/redocusaurus/psp-merchant-swagger-id.yaml) requests.
    * Optional boolean field indicating whether the merchant has accepted the Vipps MobilePay terms of service for GDPR and Privacy. Required for login, userinfo, and express features.
  * Added `companyName` field to the [Update merchant](https://developer.vippsmobilepay.com/redocusaurus/psp-merchant-swagger-id.yaml) request, allowing the merchant's legal name to be updated.

## June 2025

* Expanded the maximum length of `merchantSerialNumber` from 6 to 10 digits (pattern `^\d{5,10}$`) across all endpoints and response models.

## September 2023

* Removed `mccCode` and `logoUrl` fields from the [Get merchant](https://developer.vippsmobilepay.com/redocusaurus/psp-merchant-swagger-id.yaml) and [Get all merchants](https://developer.vippsmobilepay.com/redocusaurus/psp-merchant-swagger-id.yaml) responses. These fields were only relevant for create/update operations.

## June 2022

* v1.1.6:
  * Removed the `logo` field from the [Get merchant](https://developer.vippsmobilepay.com/redocusaurus/psp-merchant-swagger-id.yaml) response. The logo is still accepted in [Create merchant](https://developer.vippsmobilepay.com/redocusaurus/psp-merchant-swagger-id.yaml) and [Update merchant](https://developer.vippsmobilepay.com/redocusaurus/psp-merchant-swagger-id.yaml) requests.

## March 2022

* Added `logoUrl` field to [Create merchant](https://developer.vippsmobilepay.com/redocusaurus/psp-merchant-swagger-id.yaml) and [Update merchant](https://developer.vippsmobilepay.com/redocusaurus/psp-merchant-swagger-id.yaml), allowing a URL to a hosted logo image as an alternative to the Base64-encoded `logo` field.

## June 2021

* v1.1.3:
  * Added support for onboarding international (non-Norwegian) merchants. The `organizationNumber` field is now accepted for all countries, with validation applied as much as practically possible for non-Norwegian org numbers.
