Root Cause

• Unsupported Transaction Types: Attempting to process transactions like recurring payments, refunds, or pre-authorizations that the processor does not support.

• Incompatible Payment Methods: Using payment methods or card types that are not accepted by the processor.

• Missing processor capabilities: The payment processor does not support a required feature (e.g., AVS, 3DS, Level II/III data).

• Regional or currency limitations: The processor cannot process payments for specific regions or currencies.

• Outdated integration or configuration: The merchant's gateway integration does not align with updated processor capabilities.

Troubleshooting and Solutions

• Inform the customer that their payment could not be processed because the current processor does not support a required feature.

• Ask the customer to:

  • Try a different card or payment method.

  • Use a method known to be supported (e.g., Visa, MasterCard, etc.).

• Internally:

  • Review gateway and processor configurations to ensure the supported features align with accepted card types and payment flows.

  • Consider routing certain payment methods through alternative processors that support the needed feature.
