Setting up WorldPay on your Storefront shop

Before you can start accepting payments through your WorldPay account, you need to set up a merchant account with them. Mr Site customers get a great offer – get a £25 discount on the usual £75 set-up cost for a Business Gateway Plus account. 

To register your account please go here

When you’ve submitted your application, then it will be reviewed by the Acceptance Team and they’ll get in touch via email with some key information you need to set up Worldpay on Storefront. 

Linking WorldPay to Storefront 
When you receive that email, go to www.worldpay.com.  Click on ‘Account login’ at the top right of your screen. 
From the drop-down menu that appears, select ‘Business Gateway – New WorldPay Login’.


You’ll now see two options – select ‘Production Merchant Interface’ if you’re ready to start selling live, or ‘Test Merchant Interface’ if you want to test your payment process. Choose the one that’s right for you – but it’s always a good idea to test payments when you’re starting out!



For test payments:
Click on ‘Installations’ on the left-hand menu and then click the wrench image underneath ‘Integration Setup:Test’. 

This will take you through to a page with a series of fields that you will need to fill in:

Instillation ID:  This is your WorldPay Instance ID, which was sent to you in an email from the WorldPay  Acceptance team
Administration code, company name, environment: Will already be completed 
Description: Your own reference – useful if you have a few different payment gateways and want to tell how the payment was made
Customer Description: What customers will see on the payment pages, for example ‘Jane’s Shoe Shop’
Store builder used: Select ‘Other– please specify below’ from the drop-down list
Store builder: Fill in as ‘Mr Site Storefront’



For live payments:
Click on ‘Installations’ on the left-hand menu and then click the wrench image underneath ‘Integration Setup:Production’.

When you have filled these fields in, then click ‘Save changes’ and log out of WorldPay. 

Next, log into your Storefront account. Click on the ‘Settings’ tab and then click on ‘Payment methods’. Click the yellow ‘Add new’ button, tick ‘WorldPay’ and click ‘Save details’.  WorldPay will now appear on your list of payment methods. 

Click ‘Edit’ next to WorldPay and then select ‘Settings’ on the left-hand column and fill in the following fields:
