The method call that returns true only if the currently logged in user has the catalog_admin role and in no other case is g_user.hasRoleExactly('catalog_admin'). This method checks if the user has exactly one role, and returns true if it matches the argument. The other methods return true if the user has one or more roles, or if the user has any role from a list of arguments. References: [ServiceNow Docs - GlideUser API],

The step that does not belong when creating a Utils Script Include is identifying the table. A Script Include is a server-side script that can contain one or more classes or functions that can be reused by other scripts. It does not depend on a specific table, but can access any table through GlideRecord or other APIs. The other steps are part of creating a Script Include class and its prototype object.

In ServiceNow, when configuring a REST Message, the Endpoint specifies the URI (Uniform Resource Identifier) where the REST request is sent. This URI points to the resource on the external system that the REST message will interact with, whether it's to retrieve, update, create, or delete data.
Key Points:
* Endpoint Definition: The Endpoint is a complete URL that includes the protocol (e.g., HTTP or HTTPS), the domain or IP address of the external server, and the specific path to the resource. For example: https://api.example.com/v1/resources.
* Dynamic Endpoints: ServiceNow allows the use of variables within the Endpoint URL, enabling dynamic substitution at runtime. This is useful when the exact resource path or parameters need to be determined during execution.
* Configuration in ServiceNow:
* Navigate to "System Web Services" > "Outbound" > "REST Message."
* Create a new REST Message or select an existing one.
* In the REST Message record, define the Endpoint URL in the "Endpoint" field.
Example Scenario:
If you are integrating ServiceNow with an external ticketing system to retrieve incident data, the Endpoint might be something like https://api.ticketingsystem.com/incidents/{incident_id}, where {incident_id} is a placeholder that gets replaced with the actual incident ID at runtime.
Reference: For more detailed information, please refer to the official ServiceNow documentation on Outbound REST Messages.

current.<propertyname>.Thisisthesyntaxtoaccessthepropertiesofthecurrentrecordthatisassociatedwiththeevent, suchascurrent.number,current.shortdescription,orcurrent.state.Forexample,{current.short_description} will display the short description of the current record.
${property name>.getDisplayValue()}. This is the syntax to access the display value of a property of the current record, such as current.state.getDisplayValue(), current.assigned_to.getDisplayValue(), or current.
category.getDisplayValue(). For example, current.state.getDisplayValue() will display the state of the current record in a human-readable format, such as New, In Progress, or Closed.
${gs.<property name>}. This is the syntax to access the properties of the GlideSystem (gs) object, which provides methods for performing system operations, such as gs.now(), gs.getUserID(), or gs.getProperty().
For example, gs.now() will display the current date and time of the system. References: Email Notifications, Email Notification Variables
