http://hl7.org/fhir/StructureDefinition/Subscription|4.0.1

The subscription resource is used to define a push-based subscription from a server to another system. Once a subscription is registered with the server, the server checks every resource that is created or updated, and if the resource matches the given criteria, it sends a message on the defined \"channel\" so that another system can take an appropriate action.
