In your Informatica MDM Hub implementation, you can provide Hub Console users with custom buttons that can be used to extend your Informatica MDM Hub implementation. Custom buttons can give users the ability to invoke a particular external service (such as retrieving data or computing results), perform a specialized operation (such as launching a workflow), and other tasks. Custom buttons can be added to any of the following tools in the Hub Console: Merge Manager, Data Manager, and Hierarchy Manager.
Server and client-based custom functions are visible in the User Object Registry.
