A computer system may include a processor configured to search storage locations for candidate Application Programming Interface (API) files that are to be published on an Internet of Things (IoT) platform configured to interact with IoT devices for different device manufacturers. The processor may generate a list of candidate APIs based on searching the storage locations; generate a list of published platform APIs published on the IoT platform; compare the list of candidate APIs with the list of published platform APIs; generate an API create list based on the comparing; generate an API update list based on the comparing; create one or more candidate APIs from the generated API create list on a testing system; and update one or more candidate APIs from the generated API update list on the testing system.
