  • The authorization amount must be greater than zero.
  • The authorization amount can be different from the final transaction amount.
  • The authorization should not be cancelled after it is approved except when a system failure occurs.
  • The authorization must be submitted for capture within seven calendar days of its request.
  • When you do not capture the authorization, you must reverse it; otherwise, Mastercard charges an additional fee for the transaction.
