The older API user accounts, which are no longer accessible due to team members departing or their email addresses becoming inactive, are currently unavailable. Consequently, you are unable to manage or update these APIs, as the original owners are absent, and you lack the authority to edit and publish new versions. For all newly defined APIs, you have the capability to directly assign ownership to the "Architects" group. However, regarding the existing APIs, you are unable to alter their ownership on your own.
Resolution
Talend Cloud API Designer allows you to share APIs with other users and/or groups of users. For additional details, please refer to the sharing api documentation.
Note: In the Talend Cloud API Designer settings, it is possible to reassign API contracts previously created by deleted users to active connected users. This option is only available for users that have the Administrate API Designer permission enabled.
