Need help Integrating Woocomerce with Clients Bank Using Redsys Plugin

Hi
Need help Integrating Woocomerce with Clients Bank Using Redsys Plugin. I have had an online chat with yourselves and here is the plugin that is needed. Could you help with this? If you need any more information please ask and I will ask the client. She is currently using Stripe.

Below is the Email from her bank

In relation to your VIRTUAL POS request, we have found the following incidence:

In your Web https://duquesa-holidays.es/ we have not been able to carry out a purchase test through the Virtual POS in tests. For our part it is necessary to carry out a test purchase to verify that the payment process is correct. Please add this method of payment or give us access to the website in development where we can make a test purchase.

On the order hand, sadly, we do not offer the Redsys Virtual POS terminal configuration service on your web platform(modules), so you will need to contact to your web site designer to configure your virtual pos.

In http://www.redsys.es/en/index.html you will find executable modules for the integration of Redsys and also the integrations Guides.
