# API - Sep 26, 2025

## Added

### SCA session language parameter

Mangopay's hosted SCA page is automatically set to the language of the user’s browser if it is one of the following supported languages: Dutch, English, French, German, Greek (new), Italian, Polish (new), Portuguese, Spanish.

Your platform can now optionally override this default behavior by adding the `lang` query parameter to the SCA redirection URL before redirecting the user. For example, adding `&lang=es` to your URL sets the session to Spanish regardless of the user's browser language.

## Changed

### Payconiq endpoint deprecated: Decommissioning planned end of 2025

Following its acquisition by the European Payments Initiative (EPI), the Payconiq brand and services are being phased out ([read more](https://www.payconiq.be/en/payconiq-evolves) on Payconiq's website).

The timeline is as follows:

* Dec 4, 2025 - [Payconiq pay-ins](/api-reference/payconiq/create-payconiq-payin) attempted after **12:00 noon CET** will fail
* Dec 31, 2025 - Final day for processing [pay-in refunds](/api-reference/refunds/create-refund-payin)
* Jan 1, 2026 - Refunds possible using payouts ([see guide](/guides/payment-methods/payconiq#refunds-from-jan-1,-2026))

Platforms using Payconiq are invited to integrate [Bancontact](/guides/payment-methods/bancontact), which allows users to continue paying with their Payconiq by Bancontact mobile app via the `DeepLinkURL`.
