modulo de pago caja rural

Hello,
I want to install the payment gateway of Caja Rural but need to install a payment module.
Please could someone give me a link to download a module that works with this payment gateway.
thanks

Caja Rural need to tell you who they have an agreement with. It can only be Servired, 4b or CECA.
There are payment modules for all of them.

Thanks for your answer,
Caja Rural belongs to servired but servired payment module does not work with this bank because it has a unique module.
You can see this link but I look for free.

They should be providing you with the Servired standard TPV communication specification and their unique one so you can compare them and then make the necessary modifications to the standard Servired module.

I see no link.

In any case, if someone else has done the work already why not pay them for the time you will save...especially if you cannot do it yourself.
