How to expose business service as Rest endpoint

Hi Friends ,

We have requirement to load data into chache tables from external database (ref data). This process will take 1 min to complete all data load.

Currently I have created Business Service  to trigger Business Operation with out bound db adapter to load data into cache tables.

process will be trigger when i restarted business service.

But requirement  is  , this business service should be triggered from outside ensemble environment i.e , this should expose as REST endpoint and share with the external team.

How to expose Business service as REST endpoint? I need help for this regard.

Thanks in Advance
