Any API/SDK access to Canvas and/or Relay?

Hello,

Are there any endpoints via REST API or SDK for access to Box Relay and Box Canvas? I’ve seen the REST API for workflows, but it seems pretty limited. I’m interested more in admin reporting, like how many workflows are in use, how often they’re triggered, who’s triggering them, etc.

With Canvas, I’m interested in similar stats as Relay.

Any ideas are welcome.

Thanks.
