Currently Workfront provides only the option to revoke all API keys. The request for revoking a single API key results in revoking all keys and re-issuing them afterwards. This can be a quite complex procedure if Workfront is highly integrated with other business applications.
To improve availability of API access and API key management in enterprises and enable granular security actions a better API key management is needed. A first step would be the option to revoke single API keys without impacting other API keys used.
