Root Cause

• Unsupported payment method: The customer's payment method is not eligible for the transaction type due to it being unsupported in the customer's country or currency.

• Account restrictions: The customer's account does not support transactions through the selected payment method.

• Regional limitations: The payment method is not available for the customer's country or region.

• Temporary unavailability: The payment gateway or processor has temporarily disabled the selected payment method.

Troubleshooting and Solutions

• Inform the customer that their selected payment method cannot be used to complete the transaction.

• Ask the customer to:

  • Choose a different payment method available on your checkout or billing page.

  • Ensure the alternative payment method is eligible and supported for the transaction type and region.

• Guide customers to update their preferred payment method if your platform allows it.

• Monitor gateway status dashboards for any widespread disruptions affecting payment methods.
