Use the Void Create Account endpoint to cancel an account (move the account into status: B, Voided account) that was created by Create Account. Pass either the transactionId of the original Create Account call or the optional accountNo parameter to identify and void the created account. The accountNo parameter can be the PRN that was returned by Create Account or a PAN that you can retrieve using Get Account Cards.
Use Void Create Account only for instant-issue (prepaid) card accounts. To reverse an account creation for other account types, use the CST.
