Hi Bhanu,
There is no direct integration for Bizz within Apptio that I am aware of. However, Apptio does use a system called "Datalink" that allows for connecting to any REST API service an pulling in data into Apptio accordingly.
More details on using a REST connector are available in the below IBM Documentation article:
https://www.ibm.com/docs/en/apptio-platform/datalink/saas?topic=connectors-datalink-rest-service-connector
Hope this helps!
