I'm having trouble integrating a new payment provider, Handepay: they provided their own specific software to fit in to OC 3.0.2 which works fine until the customer gets to their their payment pages where we get a constant error even if the plugin is set up correctly.
We have turned off ALL mods and extensions and we still get an error.
They have asked for the encoded url that is built at our end so they can inspect it - can any one indicate how we would get that?
Thanks for your help!!
