Hey there - has anyone had any luck working with Visa Checkout and their API Key - Shared Secret (x-pay-token) setup? Their documentation suggests using SoapUI to make your first connection to construct the x-pay-token. Naturally, it is not working otherwise I would be writing. I was able to get their 'hello world' sample code working (after playing around with SoapUI for a few hours).

I am at the point in my integration whereby I send a user to Visa Checkout from their javascript widget, and I am ready to deconstruct the paypload in my checkout module. The problem is that I need to generate an x-pay-token to make the proper connection and their sample code does not work (in php or c#) so no easy way to test this other than spending lots of time hacking around.
