You can use test mode to simulate payment processing without actually causing a transaction to occur. This can be useful for testing your configuration.

Troubleshooting

Details could not be saved. Remote storage failed

This message will display when attempting to create a credit card payment method via the Admin Area or Client Area. Due to restrictions in Payflow’s Reference Payment features, this module does not support remote updating, storage, or deletion of card details.

Clients can specify a new card by viewing an invoice in the Client Area, clicking Pay Now, selecting a new credit card, and providing the card’s details.

No Local Credit Card Payment Gateways Enabled

You may encounter this error when attempting to make a payment via the Client Area if you have unchecked the option to save card details for later. Due to the reference nature of the gateway, the system must store the card details at PayPal for automated rebilling of reference transactions to function.

The system will never store client credit details on your server.
