A few users have contacted us after receiving the following email from WorldPay:
Dear Sir or Madam,
We recently sent you an email about changes to our Payment Service which may affect your connection with WorldPay.
Please read the below information carefully and where appropriate, make the necessary changes by 30 April 2013 to continue to connect to our Payment Service.
Failure to make these changes could mean that you are unable to process payments through WorldPay.
What changes do I need to make?
If your system receives automatic updates from WorldPay when shoppers make payments on your website or by telephone and you choose to restrict domain names, please ensure that you are using the following domain names:
If you use IP addresses instead of domain names to submit http, XML or Remote Administration requests to WorldPay, please change your connection to use domain-name-based URLs instead.
If you use HTML form posts:
If you use XML requests:
If you use Remote Administration:
If your website or internet connection is restricted, you will need to speak to your technical contacts that control your Domain Name Service (DNS). Please check that they are aware of the above information, refresh the DNS cache and confirm that references to rbsworldpay.com and wp3.rbsworldpay.com are replaced with worldpay.com.
Why do I need to make these changes?
WorldPay is making a significant investment in product development, next generation technology and expanding our global market coverage.
As part of this investment, we are upgrading our platform to a new data centre in 2013 and will be changing some of the IP addresses from which we send updates.
Who should I contact if I have questions?
If you would like more information on how your WorldPay account could be affected by these changes, please contact our Technical Support team on +44 (0)870 366 1233 selecting option 5 for Technical Support, or email supp...@worldpay.com.
Thank you for your support.
There is no need to make any changes to either the v1 or v2 systems as we do not reference IPs in the payment gateway. The only impact there may be would be a short delay whilst the WorldPay IPs propagate but this should not have a significant impact on your service.
