1. A method for reporting Application Programming Interface (API) capability change according to an API filter, the method comprising:
at a first node within a telecommunication core network, which first node comprises a combined Service Capability Exposure Function (SCEF) and Network Exposure Function (NEF):
receiving, from a requesting entity that comprises an Application Function (AF), a monitoring request to be notified of an API capability change related to an identified wireless device associated with a service API, the monitoring request identifying a subset of one or more APIs in which the AF is interested to have monitored;
subscribing to receive notifications of a core network type change for the identified wireless device;
receiving a notification that the identified wireless device has changed from a first type of core network to a second type of core network;
determining an API capability change from the first type of core network to the second type of core network for the identified subset of one or more APIs in which the AF is interested and filtering out all but the APIs in which the AF is interested; and
reporting, to the requesting entity, the API capability change for the identified subset of one or more APIs in which the AF is interested and not reporting the API capability change for other APIs not in the identified subset.
