Important update​

📎 Swan is regenerating all bank details PDFs created before November 4, 2025, to reflect Swan SAS's new address. Bank details generated after this date already contain the new address.

This applies to both main and virtual IBANs. Subscribe to the Account.Updated webhook to synchronize your system. This webhook is triggered only when main IBAN bank details are regenerated. Query your virtual IBANs separately to synchronize them as well.

The process happens in two stages:

  • Starting Friday, January 30, regeneration begins in Production Sandbox.
  • Starting Monday, February 2, regeneration begins in Production Live, pending successful completion of Production Sandbox. It should take one week to complete.

Improvements​

🧭 SEPA Credit Transfers received without a customer-provided reference now display as empty strings in Web Banking and the API, instead of showing NotProvided.

📖 Identify which user initiated a credit transfer by querying the payment before consent is granted, or by storing user details at the time of initiation.

🔧 The reference field for standing orders has been updated to align with SEPA scheme requirements: the underscore character (_) is no longer accepted. New regex pattern: ^[A-Za-z0-9-?.+\/:,'() ]{1,35}$.

Upcoming breaking changes​

👮 Starting February 5, new rejections apply to the openAccount mutation to prevent fraud patterns involving successive opening and closing of multiple accounts to bypass the account creation limit:

  • All accounts now count toward the maximum limit regardless of status (Opened, Suspended, Closing, or Closed). Previously, only Opened accounts counted. This change affects the existing AccountHolderAccountsCreationLimitRejection.
  • If one or more of the account holder's accounts is Suspended, Swan rejects opening multiple accounts with AccountHolderAccountsSuspendedStatusNotEligibleRejection.

🚫 Starting February 26, the following rules apply to limited accounts:

  • Incoming SEPA Credit Transfers (instant or regular) exceeding €50 are automatically rejected.
  • The maximum cumulative balance is €150.
  • Any incoming SEPA Credit Transfer, regardless of amount, that would cause the balance to exceed this limit is also rejected.
  • Any incoming SWIFT transfer, regardless of amount, is automatically rejected.

This change mainly affects the first incoming transfer made while the account holder is still completing verification. During verification, the account remains limited, and any transfer exceeding these limits is automatically rejected.

Capital deposit accounts are unaffected, except that all transfers sent on SWIFT are now rejected for these accounts as well.
