Continuous Authority transactions, otherwise known as Recurring Billing, is an industry wide term used to describe a transaction for which a cardholder grants written permission to a Vendor to periodically charge their card for recurring goods or services such as club membership or magazine subscriptions.

While the Protx system is not set up specifically with Recurring Billing or Subscription Payment services, it is possible to process repeat Internet transactions using a Continuous Authority Internet Merchant Number via our Payment Gateway system.

Continuous Authority is for vendors who regularly take payments from shopper's cards (weekly, monthly or yearly). Protx provide a Repeat transaction type option on all Protx accounts but this is for the occasional repeated transaction, not for multiple repeats. The banks will provide a Continuous Authority Internet Merchant number for all vendors who wish to process repeat payments of this nature.

Transactions that are processed online with the banks require a CV2 Value and an Expiry date. But CV2 values cannot be stored and expiry dates can expire, so processing a Repeat transaction has its restrictions.

Continuous Authority transactions do not require a CV2 value or expiry date. The initial transaction, once verified, will be a trusted card and will not need to have the data passed again. If the card expires, as long as the card number has not changed, it can still be processed.

You will need to obtain a Continuous Authority Internet Merchant number from your Acquiring bank and establish their requirements. For Bank contact details click here

VSP Direct Vendors

The VSP Direct system allows you to pass an 'AccountType' field, allowing you to choose what type of transactions you wish to process. You manage the data flow, so you can pass an 'E' for an Ecommerce transaction, an 'M' for a Moto transactions and a 'C' for a C Continuous Authority transaction and we will handle them accordingly.

N.B: Using VSP Direct requires you to capture the card details and pass them to our system, so you will need a secure environment.
