Activate and Use Decision Applications

After modeling a decision and exposing it as a service, you must activate the decision application so that the decision service exposed can be used by other process applications and external applications.

1. Activate the decision application. See Activate an Application Version.
   To know more about working with snapshots and versions, see the following topics:

   • Work with Snapshots
   • Work with Versions
2. Use the activated decision application in process applications as external decision. See Understand Local and External Decisions.

   You can call the decision services of an activated decision application from other process applications. First, create an external decision with the activated decision application and then use the exposed decision services in processes of your process application.

   • Create a Local or External Decision
   • Add Decision Services to Processes
3. Use the activated decision application in external applications.

   You can call the decision services of an activated decision application from external applications. You use the decision service REST API endpoint URL, the request payload and the response payload in a POST operation to call the decision service from an external application.
