摘要

PROBLEM TO BE SOLVED: To provide an API cooperation device capable of suitably cooperating with a plurality of external authentication server devices by making it unnecessary to mount a plurality of authentication API in an API use device.SOLUTION: A cooperation part 44 of an API cooperation device 40 is configured to, when an authentication response to one API request shows authentication success, refer to an ID information storage part 42 by using a user ID included in one API request, and to read the user ID in another external authentication server 30 corresponding to the user ID, and to transmit the API request to the other external authentication server device 30 on the basis of the read user ID, and to receive an authentication response by the other external authentication server device 30, and to transmit the received authentication response as well as the authentication response to one API request to an API use device 10.SELECTED DRAWING: Figure 1
