Root Cause

• Card issuer restrictions: The card issuer explicitly prohibits surcharges on transactions using their cards.

• Merchant configuration issues: Attempting to apply a surcharge to card types or jurisdictions where surcharges are not permitted.

• Compliance regulations: Certain jurisdictions or payment networks prohibit the addition of surcharges.

Troubleshooting and Solutions

• Ask the customer to:

  • Retry using a different card or payment method that allows surcharges.

• Internally:

  • Verify the applicability of surcharges on specific card types and ensure compliance with regional regulations.

  • Update merchant configurations to prevent surcharge application for disallowed card types or regions.
