Has anyone ever done an integration between Workfront and Contently's proprietary workflow system?

We are starting an engagement with Contently to write Content for us. They have a workflow system in house that the need their team to use. Obviously we would like for the work to also be tracked/documented in Workfront. I know through APIs that an integration would be doable, but was wondering if anyone had actually done it?
