Add Bank Account to a Payment Account for Money-Outs

You are required to register your client's bank account details in order to send Money-Out from a Lemonway payment account.
With this method, our system links other bank formats to a payment account.

Important: If your client bank account details are in IBAN format this call.

  • Client bank account details are only required for money-outs.
  • When you link a new bank account (IBAN format or other ones), the previous ones are still active.
  • Please use IbanUnregisterPut method to deactivate a bank account from a payment account.
  • If you wish to use only one bank account per payment account, please contact support.

Depending on bank country code selected or when a USD environment is concerned, 3 fields may be required:

  • bankBranchRoutingCode
  • bankName
  • bankBranchAddress

Use this endpoint to register your client’s bank details (IBAN or other formats) for outbound transfers (Money‑Out) from their Lemonway payment account.

Key points:

  • Purpose: Bank details are only needed for Money‑Out transactions.

  • IBAN accounts: If you’re adding an IBAN, use the dedicated IBAN registration call.

  • Multiple accounts: Adding a new bank account does not disable previously registered accounts.

  • Unregistering: To deactivate an existing account, use the IbanUnregisterPut endpoint.

  • Single‑account option: To restrict to one bank account per payment account, contact Lemonway support.

  • Additional fields: For certain country codes (or USD environments), you must also supply:

    • bankBranchRoutingCode
    • bankName
    • bankBranchAddress

Important: Whenever you see accountId in a path or body parameter, enter your wallet’s ID.
