Online Payment Methods   Set Up 

This section deals with the methods supported by CactuShop for accepting 

online payments. 

IMPORTANT: We would strongly recommend using an online gateway to 

accept credit card payments for a number of reasons. Firstly, they maximize 

security. The card details are given on the gateway's own site, so you and 

your site never see the credit card details. Even if your site or web host was 

ever compromised, credit card numbers could not be stolen. Secondly, online 

gateways have a number of security checks in place, reducing the likelihood 

of fraud against you (it is the merchant that bears the cost of fraud). Finally, 

online gateways are easier to set up (no need for SSL or encryption software) 

and easier to use (since the transaction process is largely automated). 

Many merchants do not realize that using an online authorization service does 

NOT mean that you have to bill cards immediately a transaction is made. Most 

of the systems provide the option of authorizing a card and then billing it later 

at a time of your choosing. This is useful when you need to only bill the 

customer after the goods are despatched, or if you wish to carry out other 

checks before accepting the order.

8.1.1 About 

WorldPay 

For further WorldPay information, see 

www.worldpay.com

and read WorldPay's 

documentation. 

WorldPay is a major provider for online credit card transactions. By using the 

scripts provided, CactuShop can easily be configured to use WorldPay for 

payment. You will need WorldPay to set up an account for you on their 

system. The CactuShop software handles the entire ordering process and 

formats the customer and order details in a form for submission to WorldPay. 

The customer then inputs credit card details at WorldPay s secure site. Once 

the transaction has been completed, WorldPay informs your CactuShop, which 

updates its records to show the status of the transaction and sends order 

notification to you and the customer (if required). 

One big advantage of using an external card payment system like WorldPay is 

that you do not need to implement SSL on your site since the card details are 

entered on WorldPay's system. 

Some configuration to your account must be done at WorldPay s Web site 

(WorldPay will have supplied you with access details). This is referred to as 

WorldPay s Merchant Management System. 

The WorldPay scripts are: 

WORLDPAY_mailorder.asp

WORLDPAY_callback.asp

They are located on the root of the CactuShop web.
