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