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• Outdated integration or configuration: The gateway integration does not align with updated processor capabilities.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.
• Ask the customer to use a method known to be supported (e.g., Visa, MasterCard, etc.).
• 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.
• If the problem persists, contact Chargebee Support for further investigation and resolution.
