Question

Common Web Service across multiple Pega Applications
Hi Everyone!
We are using Pega 7 and have multiple Pega applications on the same instance which are logically separated through the class structure. I want to build a common inbound web service which will be used to create/update/inactivate an operator record. Depending on the application the user belongs to (defined in the payload) custom business logic needs to be invoked depending on the application eg. superuser needs to be notified.
As I am a newbie I was wondering how we can design a Pega Inbound Web service to notify all Pega applications which use the service when a payload is received from an external system?
Thanks
