Root Cause

• Depleted gift card: The gift card has already been used, and the balance is zero.
• Expired or inactive card: The gift card is no longer valid or has been deactivated.
• Incorrect balance check: The system attempted to charge an amount greater than the remaining balance without a partial payment fallback.

Troubleshooting and Solutions

• Inform the customer that their gift card has no remaining balance.
• Ask the customer to use a different payment method to complete the transaction.
• Ask the customer to contact the card issuer if they believe the card should still have funds.
• If supported, implement logic to allow partial payment with gift cards, followed by a secondary payment method.
• Evaluate if you want to block prepaid cards at the entry going forward if similar failures happen.
