+# Create Service Catalog Request Programmatically
+
+## Description
+This snippet demonstrates how to programmatically create a Service Catalog request using the CartJS API from server-side code. It bypasses the Service Portal interface and directly adds items to a cart, populates variables, and completes the checkout process.
+
+## Use Cases
+- Automated hardware provisioning workflows
+- Integration endpoints that trigger catalog requests
+- Business Rules that create catalog items based on conditions
+- Scheduled Jobs that batch-create catalog requests
+- UI Actions that automate catalog submissions
+- Custom approval processes that generate follow-up requests
+
+## Prerequisites
+- Service Catalog Scoped API plugin enabled (com.glideapp.servicecatalog.scoped.api)
+- Valid catalog item sys_id
+- Variable names must match exactly as defined in the catalog item
+
+## Key Features
+- Populates catalog item variables dynamically
+- Automatically checks out the cart
+- Returns request ID and number for reference
+- Can be used in any server-side context (Business Rules, Script Includes, etc.)
+
+## Notes
+- Two-step checkout setting affects the return value
+- If two-step checkout is enabled, returns cart_id
+- If two-step checkout is disabled, returns request_id and request_number
+- Replace placeholder sys_ids with actual values from your instance
