How do authorisations work?

When your customer pays during a transaction, we send the amount of the transaction to your customer's card issuer for authorisation, which protects you by ensuring your customer’s account is in good standing and the customer has money available so you can be paid. The issuer's processor places the amount on ‘hold’ and removes the amount immediately from your customer’s available balance. The hold is released based upon parameters set at the processor (approximately 72 hours for debit cards; the timing varies for credit cards) or when the transaction clears, whichever comes first.
