+This is a server-side Script Include that contains the core logic. It reads the endpoint configurations from a System Property, parses the JSON, and returns the appropriate URL based on the current instance's name.
+
+System Property: x_my_scope.api.endpoints
+This property stores a JSON object containing the endpoint URLs for each environment. It must be created and populated in each instance that uses the utility.
+
+Sample JSON object:
+{
+  "dev": "https://dev-instance.example.com/api",
+  "test": "https://test-instance.example.com/api",
+  "prod": "https://prod-instance.example.com/api"
+}
+
+Usage:
+var endpointConfig = new EndpointConfig();
+var endpointUrl = endpointConfig.getEndpoint();    
+if (endpointUrl) 
+{
+  gs.info("Endpoint URL: " + endpointUrl);  
+//Use the endpointUrl in your REST call
+  var request = new sn_ws.RESTMessageV2();
+  request.setEndpoint(endpointUrl);
+    // ... rest of your integration logic        
+} else {
+        gs.error("Failed to retrieve endpoint URL.");
+    }
