Additionally, please note that this endpoint can be used to change the input and output parameters of an automation package only if you did **not** upload it to Orchestrator through the API, the **Packages** page, or the NuGet feed. ::: If you want to update the values of input parameters only, you can do so at [process level](https://docs.uipath.com/orchestrator/automation-suite/2024.10/api-guide/processes-requests#processes-requests), at [job level](https://docs.uipath.com/orchestrator/automation-suite/2024.10/api-guide/jobs-requests#jobs-requests), and/or [schedule level](https://docs.uipath.com/orchestrator/automation-suite/2024.10/api-guide/schedules-requests#schedules-requests) .
