(.net) OWIN stand alone application

Hi App Dynamics!

I'm trying to send some metrics from a REST API running on an OWIN app (which uses Nancy). Is there a business transaction rule that we could add for it to automatically create business transactions?

I tried to follow a suggestion on this question, but didn't manage to configure it (maybe because the UI has changed?) https://community.appdynamics.com/t5/AppDynamics-Discussions/Azure-Cloud-Service-Not-always-auto-instrumenting/td-p/20353

Thanks!
