Ds_Merchant_PayMethods Support

Here is an initial patch that worked fine for the Banc Sabadell. I'm not sure if will be different for other banks, but probably not, as Sermepa is a generic sollution for all the banks using this system.

I guess it will be better to use a field where you can select multiple values and then concatenate them in the submit function. But for now, this patch should do the trick.

We have confirmed that this patch also works for "La caixa" bank.

Hello, thank you very much for the work done! but I think we can improve the approach...

According to the official documentation, we have to provide independent buttons for each payment method.

We will create two new payment methods, the internal operation of signature and validation are the same.

Also we have to add the Ds_Merchant_PayMethods parameter but not configurable, each method should be sending it with its corresponding value.

Dato => Formas de pago a usar
Nombre del dato => Ds_Merchant_PayMethods
Longitud/Tipo => - (No se especifica longitud) / Alfanumérico
Comentarios: => Campo opcional que permite seleccionar que formas de pago se podrán usar en la operación. Se podrán especificar varias de ellas concatenadas, por ejemplo: “TVO”, “TV”, "TO", "VO", "T". A la hora de concatenar los valores, el orden no importa ni afecta.
Posibles valores:
C - TARJETA
D - DOMICILIACIÓN (Sólo bancos que lo soportan)
R - TRANSFERENCIA (Sólo bancos que lo soportan)
T - TARJETA IUPAY (Debe estar activa esta forma de pago)
O - IUPAY (Debe estar activa esta forma de pago)
V - V.ME (Debe estar activa esta forma de pago)

En blanco: todos los métodos de pago disponibles para el comercio.

We should also add images of the methods.

So I think it will give us some more work to implement this feature...

pcambra, we invoke you! We want your review

I think we can have new payment methods, if we get into the path of having this just as settings it won't end well for us.

So we could either have submodules or plugins to define these. If the validation and return are the same, that should stay in the main module.

Is there any progress with the implementation of the iupay method?

Thanks!

Thanks!

It seems that for new accounts is mandatory iupay button, so I've created a new patch, which requires this other: #2794393: Add supported card icons on payment selector
