Yes. Prommt accepts Diners Club to process payments.

If you are receiving a failure due to this card type, then you should contact your Payment Gateway provider and ask them to review. Some Payment Gateways do not have this enabled as a default setting, meaning they must update your Payment Gateway account.

Prommt pushes transactions to and from the merchant and the payment gateway. Prommt does not interfere with the settings you have in place with your payment gateway, so you will need to contact your gateway to inquire about these settings.

Please Note: some Payment Gateway providers charge additional fees to process these card types, so please inquire with the Payment Gateway before requesting any changes.
