Abstract: The present disclosure relates to a gateway device supporting integral processing of APIs with security function, and a method of operating the gateway device. In more detail, the present disclosure relates to a gateway device for integrally processing APIs with a security function, the gateway device supporting a security function that notifies of a security danger when a problem is generated by analyzing logs in the process of API calling and responding and supporting a security function that increases security for a new environment in which calling of several API servers and responding are repeated in a gateway by applying a function of integrally processing a plurality of API functions by registering the API functions into a unit API service to the gateway, and a method of operating the gateway device.

Abstract: The present disclosure relates to a gateway device for integrally processing APIs and a method of operation same. In more detail, the present disclosure relates to gateway device for integrally processing APIs that gives support to be able to set and register an execution type such that a client device can execute a plurality of APIs corresponding to an API-based service in series or in parallel and accordingly that gives support such that the client device executes a plurality of APIs in accordance with a pre-registered execution type only by requesting a service without a need for directly calling an API while communicating with a plurality of API servers and a service execution result required by the client device is provided with a minimum traffic, and a method of operating the gateway device.
