Integrating 3D Secure into Payius payment system

Question

Is there anyone familiar with Payius payment system?

I have integrated the system in one website and now I have to add 3DS step. The only documentation I found (http://payius.com/media/pdf/Payius-Merchant-Integration-Giude.pdf) says I need to redirect the user to url https:///merchant/mpi which will perform a get request to the referrer as a callback. Now as I understand for testing purposes the url should be https://testpayments.payius.com/merchant/mpi right? In any case both bring up en error.

Did I get the documentation right?

Answer 1

Ok, the correct url for testing is https://testpayments.payius.com/merchant/mpi. It appears the mistake was in passed parameters. If you do not pass needed request parameters, the page will not be loaded at all.
