Has anyone configured the Dynamics 365 extractor? Does anyone know the syntax for the configuration parameter endpoint?

Things I found helpful: 

1. Documentation in bitbucket (small link in D365 component header):863
2. Go to base_url/api/data/v9.x/EntityDefinitions?%24select=EntitySetName (found this in error message and in document) to get JSON results of all entity definitions.
3. endpoint is simply just the name..  endpoint url will be built for you...  e.g. account for account endpoint.
4. Query can be empty..this will pull all results.  Would be same as using " $select=* "
