Wallets API


🆕 New Features

  • Temporary - Bancontact onboarding endpoint — POST /temp/wsp/wallets/{sub}/bancontact for WSP-initiated Bancontact onboarding without full validation (will be removed in a future release).
  • Now supported to use BANCONTACT as Participating payment system in Create payment instrument session​. Up until now it was only there for documentation.

⚠️ Changes

🐛 Bug Fixes

  • Now displaying previously hidden parameter redirectUri in Create payment instrument session. This URL will be used to redirect the consumer back to a specific app/webpage after a payment instrument onboarding is complete.
  • Add missing field merchantReference to WSP Transaction lookup response objects.
