Thanks Jerome
That's most helpful and I can and do appreciate you letting us know why you/HikaShop can't do something with the plugin at this time.
One thing I would ask, if you could, you mention we are free to edit the plugin and change the url in it. Can you outline where that would be? I looked through the basic setup for the plugin and couldn't find it there, just the Merchant id/password etc.
You mentioned that the official developer doc was current as of April 2016, that is actually a little outside the big push Google and others made for the switch to a more secured internet, and given that most companies are waiting for some time next year to do their shifts, I kind of applaud VirtualMerchant for being ahead of the game and getting things done before the big online shopping season.
I have spoken with Elavon, one of their agents and pointed out the DeveloperGuide.pdf, page 7 does not reflect the shift in the production URLs as you pointed out.
Having said that, Converge, by way of the emails indicated the new environment via their testing site for APi.

When I emailed Elavon about the issue and their lack of updating their own documentation, I did request that they provide some sort of extension because we do not all have the luxury of a developer on staff, and use plugins like HikaShop to allow us to do business. I'll update if I hear anything, but could you outline how we would change the URL regardless?
