Integration with Cucumber results and TestRail

I use TestRail for a manual test case management tool. I’d like to have my automation results show up there as well. For my current automation set up, Cucumber is running the automation suite in our CCI environment. It spits out a json results file in the artifacts tab of the build. Has anyone successfully sent this data over to TestRail before? I found a github repo that gives instructions on how to do this, but I’m just wondering if someone has done this before and how difficult it is to get working.
