Awesome project. Was poking around to see how the sources are generated, but it seems like the repo doesn't exist (or was made private)?
https://github.com/fastenhealth/fasten-sources-gen
- Epic: https://open.epic.com/MyApps/Endpoints - Cerner: https://github.com/cerner/ignite-endpoints
It will be open sourced (eventually) -- once I've cleaned up some test credentials that were inadvertently committed to the repo.
Hope that answers your question?
