6. “Event-driven APIs are a new style
of API that uses a subscription
“push” model rather than the
request-response model of
conventional RESTful APIs.
Architects must develop new
approaches to mediating and
governing event-driven APIs,
because API management
platforms designed only for
RESTful APIs may not be sufficient.”

Services”, 24 Sept 2020, Twiggy Lo, Brendan Williams

17. “Solace recently introduced an Event API
Product capability to invoke individual
messaging flows cataloged in the Event
Portal, making it possible to subscribe to
both business-level and complex types of
events as well as trigger the execution of the
event APIs.
“The introduction of the event API products,
along with the visualization and
manageability of the underlying messaging
needed to execute the APIs, means that
response speed and resilience improve
across what can be highly distributed
systems.”
