Which of the following is NOT an option for configuring the Service Portal?

The Programmer's Toolkit is not a configuration option for the Service Portal in ServiceNow. Instead, it is a set of tools and APIs that developers use to build applications or enhance ServiceNow instances. While it does provide important functionalities for developers, it does not directly pertain to the configuration or design aspects of the Service Portal.

In contrast, options like Page Editor, Designer, and Widget Editor are specifically tailored for creating and managing the user interface of Service Portal. The Page Editor allows users to modify and arrange pages, making it easier to lay out content as needed. The Designer provides a comprehensive visual interface for managing portal elements without requiring in-depth coding knowledge. The Widget Editor enables users to create and customize widgets, allowing for interactive and dynamic components on the portal. All of these tools are inherently linked to configuring and optimizing the Service Portal experience for end-users.
