+# ServiceNow Script: Submit Catalog Item via Scheduled Job
+
+This script demonstrates how to programmatically submit a ServiceNow **catalog item** using the `Cart` API. It is designed to be run as a **Background Script** or adapted into a **Scheduled Job**. The script includes error handling and logging, and can be extended to support additional use cases such as variable injection or duplicate request prevention.
+
+## 📜 Overview
+
+This script performs the following actions:
+
+1. Generates a unique cart ID.
+2. Creates a new cart using the `Cart` API.
+3. Adds a catalog item to the cart (no variables required).
+4. Places the order.
+5. Logs success or error messages.
