Card payment error - 508 Mandatory field missing. HPP_BILLING_CITY not present in request. Please contact the merchant

Question

I am using realex payment 3DS2 on ectdrains.co.uk and after i hit "Pay Now" on the checkout page it return this Error: 508 Mandatory field missing. HPP_BILLING_CITY not present in request. Please contact the merchant.

Any idea what is mean and how to solve this issue?

The billing_city is added to checkout page:

Answer 1

It would be worth checking that the billing_city is mapping to the HPP_BILLING_CITY field when it's submitted. Looking at your site, if you're using Wordpress / WooCommerce then I'd suggest making sure your plugins are up to date.

Answer 2

Please download and install the latest extension/plugins and that should go away.
