Why did I receive this chargeback?

The amount of the authorization approval was less than the amount you charged the card.

What compelling evidence is needed to respond?

Your chargeback response must include at least one of the following items:

  • If you processed the transaction correctly, provide an authorization approval for the full amount or proof that the purchase was an exception to the rule.
  • If you have already processed a refund for the transaction in question, provide documentation that proves you have credited the cardholder’s account.

How can I avoid this chargeback in the future?

  • Don’t change the amount of a transaction once authorization has been requested and approved.
  • If you add gratuities to transactions, don’t exceed the acceptable limit.
