Wallets API

🆕 New features

• merchantReference now being sent to the WSP on Process WLW transaction result request​.
• Add support for query parameters in XTRA/CG-SDD redirect deeplink URL.
• Free sorting of all payment methods. No longer restrictions based on WSP settings.
• New Response codes​:
  • 68619 -> Transaction expired
    • No further action is allowed to happen for this transaction. The use case for this new response code is if a transaction hasn't been either cancelled nor signed by the consumer within the Aera-defined timeout value of WLW transactions. Then the ECR will receive this in the Merchant callback or when performing Get Wallet Payment status​ as the externalResponseCode.

⚠️ Changes/important information

• Previously, we stated that we were going to remove the fields status from Get transaction status , brand and scheme in transactionDetails from Merchant callback and Get transaction status in release 2026.06.00. This will not happen until 2027, and the fields will stay as deprecated fields until then. More information about the exact release when it will be removed will be communicated during last quarter of 2026.

🐛 Bugfix

• More robust integration towards PSP for handling transactions.
• Improved duplicate validation for XTRA/CG-SDD payment methods (using `accountHolderId`).

  • 📘

    As always; if duplicates are detected, no new payment method will be created, but all the information coming from the issuer will be updated (e.g. IBAN, bank name etc) on the existing payment method.

• More robust WspTransactionHistory implementation.
