Abstract
Systems and methods for a dynamic encryption model in which dynamic encryption keys are associated with an access token having an expiration time. The access token is generated for a user session of a user application seeking to make API calls to a service provider system. When the access token expires, or becomes otherwise invalid, the dynamic encryption keys are discarded, and any further API calls are made using an updated access token and updated dynamic encryption keys. The dynamic encryption keys are used to encrypt specially designated fields of API calls and/or API call results.
