An API gateway hosts one or more APIs for use by client applications. The API gateway includes facilities for maintaining state information on behalf of a client application, a backend service, or an API. The state information may include cached information retrieved from backend services as well as cached results returned from the API to the customer applications. Cached results generated by the API may be shared across a number of customers or across a set of APIs managed by a single API gateway. Cached information associated with a backend service may be shared across a number of APIs that access the backend service. In some examples, session information associated with secure connections between an API gateway service and a backend service provider is maintained by the API gateway service and shared among APIs hosted by the API gateway service.
