Click here to create an account with WorldPay.

Once you have opened your account with WorldPay and been accepted, open your Ecommerce Plus Template admin pages and go to the Payment Provider section.

Now click on Modify next to WorldPay.

Where it says "Account Number" you want to enter the "Installation ID" that was sent to you by WorldPay.

IMPORTANT NOTE: Make sure it is your installation ID and not your company ID that you enter. The 2 numbers are very similar and can easily be confused.
Make sure that the Enabled and Demo Mode checkboxes are checked.
Please note that WorldPay would have given you a password to enter their administration area. You do NOT want to enter that into the Ecommerce Template admin area.

Now go to the WorldPay online administration area at
http://support.worldpay.com/admin/
Here you need to enter your WorldPay username and password.
The type of integration you want is "Select Junior". This is the default when you setup an account with WorldPay, so leave this as it is.
Now at the bottom-right of the screen, choose "Configuration Options".
Set the Merchant's shop URL to the URL of your store.

With your Ecommerce Plus template, in the admin directory, you will notice that you have a file called wpconfirm.asp. You want to set the "Callback URL" to point to this file. So for instance it might be . . .
http://www.yourstore.com/vsadmin/wpconfirm.asp
Make sure the "Callback Enabled" checkbox is checked.
Make sure the "Use callback response" checkbox is checked.
Now click "save changes".

While your WorldPay account is in test mode you can use the following Credit Card number for testing purposes . . .
4000 0000 0000 0002
. . . along with any valid (ie in the next 5 years) expiry date.
You are strongly encouraged to fully test the system.

After testing make sure to take your Ecommerce Plus template OUT of demo mode in the Payment Providers admin page.
 

WorldPay allows you to receive orders via credit card in multiple currencies.

Once a customer has added an item or items to their shopping cart and clicked on "Checkout" they are taken to a form to enter their personal details, once this is completed the customer can check their purchase total, and if they are in agreement will be forwarded to the secure WorldPay server to give their credit card details. Most of the WorldPay form is pre-populated by the details given on the store form so it only takes a moment to add the credit card number in a secure environment, and be sent back to the store again.

When the transaction has gone through, the buyer will receive a confirmation email from WorldPay and the seller will be informed that there has been an order on the store.

NOTE: From Version 4.3.0 the 4 digit address validation code is now added to the auth code for Worldpay transactions. To interpret this code please click here.
