I tried searching but I couldn't find anything related to programmatically managing PDIs like resetting, activating plugins, etc. Not inside the instance itself, but inside of the developer portal.
The fact that there is no public API for the developer portal comes directly from Service now official documentation regarding Personal Developer Instances (pdi).
Their official guides explicitly state that pdi operations—such as activating plugins, resetting instances, or upgrading versions—must be done manually by logging directly into the Service now Developer Site UI.
There are no endpoints published in the Service now REST API Reference or the API Explorer meant for managing thedeveloper.servicenow.com site itself.
