Subscribers are application instances or Perspectium-supported agents that listen for and then consume data from sharing instances. The Subscribe module (under Perspectium > Replicator) allows you to set up the configurations for a subscribing action on data that is being shared from other applications, databases, or agents.
Configure a ServiceNow instance as a subscriber
Set up a subscribe action and a subscribed queue that will allow shared data to arrive at your ServiceNow instance.
