Initial setup was the thing I liked the most. The documentation on our first steps was pretty straightforward. Review collected by and hosted on G2.com.
Well, a lot of small problems were caused by slightly different test environment. After we did a lot of payments through test and we tried prod some things like 3DS didn't work as they should've. Also documentation wasn't quite clear and didn't contain some of the items we needed to make it work with on-site checkouts. Review collected by and hosted on G2.com.
