The Key Manager handles all clients, security, and access token-related operations. In a typical API Manager production deployment, different components talk to the Key Manager component for achieving different tasks. The API Gateway connects with the Key Manager to check the validity of OAuth tokens, subscriptions, and API invocations. When a subscriber generates an access token to the application using the API Store, the Store makes a call to the API Gateway, which in turn connects with the Key Manager to create an OAuth App and obtain obtains an access token.
