# PrivatePDM The "PrivatePDM" plugin allows you to add a new attribute that is required in the API flow but is not necessarily present in the input or output attributes. This is a transient attribute that can be used within the API. ### How to Use? Drag the PrivatePDM plugin into your API flow. Click **Add New Field** to create an attribute and define its attribute name and datatype in the Input and Output Configuration tabs. ### Use cases Use private PDM to define an attribute that stores the job ID (a temporary value) of a job process. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
