Can a Topology be called as a REST microservice?

Hello,

I am able to create Data Collector REST microservice pipelines, as introduced in this tutorial: https://streamsets.com/blog/create-microservice-pipelines-with-streamsets-data-collector-tutorial/

I also know how to connect Data Collector pipelines to other Data Collector or Transformer pipelines, forming a Topology, via Kafka.

However I am struggling to see how a Topology consisting of more than one pipeline can be called as a whole, via REST. In particular I would like to be able to call a REST service that combines processing in Data Collector and Transformer.

If anyone could confirm this is possible and share an example, it would be greatly appreciated.
