Hi @fuhrersk8,
Although this document is correct, it might not be easiest way to follow it up, as there is a huge difference between versions. Take a look at this article, where guys explained it in great way, with v2.4, which is much closer to v3.0.
I did such an integration, and it is straight forward, but I don't have it next to me to check your question about logs. I would expect to find this information in Admin Logins too. Most likely, t you are hitting CSCvu63833 (less likely CSCvx43566), so I would advise to go for latest patch 4.
After patching, try again to check what is going on.
BR,
Milos
