Claim 4:
5. The gateway device of claim 4, wherein when the API execution type is a first combination type in which parallel execution and serial execution are sequentially combined, the integrally-performing unit:
applies search information included in the request information to a first API and a second API that are serial execution objects having the same execution order in the plurality of APIs, and requests and receives first response information corresponding to the first API, to which the search information has been applied, through communication with a first API server corresponding to the first API;
requests and receives second response information corresponding to the second API, to which the search information has been applied, through communication with a second API server corresponding to the second API; and then
creates a first response result by merging the first response information and the second response information; and
applies the first response result, as an input value, to a third API that is a serial execution API recognized in accordance with the first combination type, and requests and receives third response information corresponding to the third API, to which the first response result has been applied, through communication with a third API server corresponding to the third API; and then
creates a service execution result based on the third response information.
