POST /temp/wsp/wallets/{sub}/bancontactfor WSP-initiated Bancontact onboarding without full validation (will be removed in a future release). - Now supported to use
BANCONTACTas Participating payment system in Create payment instrument session. Up until now it was only there for documentation.
⚠️ Changes
schemefield deprecated —paymentMethodreplaces brand/scheme intransactionDetails(old field retained for backward compatibility until next release). This change effects these endpoints:-

The Participating payment system XTRA, will remain as
PaymentInstrumentType = CARD. It was previously stated under Payment methods that this would change.
