Provided are methods and systems for application program interface (API) management. An API management device may receive requests from client devices to submit an API and/or API update for implementation. The API management device may determine an operable status of the API and/or the API update by determining whether the API and/or the API update is configured and/or updated for implementation. The API and/or the API update may be determined to be configured and/or updated for implementation when the API and/or the API update does not violate one or more rules. The API management device, based on operable status, may allow or deny the request for implementation.
