Transaction has been denied : Payment refused by the financial institution

You may have received this error while processing a transaction:

“The transaction has been denied | Payment not accepted: Payment refused by the financial institution.”

This is mainly because of the total charge amount of the transaction is too high.

When the plugin is in test mode, the maximum amount you can place in a single order is £100.00. Hence we would recommend starting out with processing a test transaction worth £10.
