WHAT IT DOES

What update_pan_element does on Postman

AI agents use update_pan_element to create or update resources in Postman — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Postman environment.

WHY IT NEEDS A POLICY

Why update_pan_element needs a policy

The tool performs an update operation on API Network elements or folders, which is a reversible modification of data. This fits the Write category (creates or modifies data reversibly). Severity is medium because unauthorized updates to API network elements could affect API documentation, configuration, or access control, but are generally reversible and lack the destructive finality of a delete operation.

From the tool's definition Tool description states 'Update element or folder in Private API Network' — this modifies existing data (element or folder) in a network structure.
