 Note that you can ignore any of these arguments except the first argument which is the axios instance to observe.

+### Observing request outside incoming request context 
+Monitoring outgoing requests inside an incoming request' context 
+associates both request in the dashboard. You can also monitor 
+outgoing requests outside an incoming requests' context 
+in a background job for example. To achieve this, instead of calling `observeAxios` as a standalone function 
+use the method on the APIToolkit client after initialization 
+
+#### Example 
+```js
+import axios from 'axios'
+import { APIToolkit } from 'apitoolkit-express';
+
+
+const apitoolkitClient = APIToolkit.NewClient({
+  apiKey: '<API_KEY>',
+});
+// using the above initialized client, 
+// you can monitor outgoing requests anywhere in your application.
+
+const response = await apitoolkitClient.observeAxios(axios).get(`${baseURL}/ping`);
+console.log(response.data)
+```
+The above request will show in the log explorer as a standalone outgoing request 
+
 ## Reporting errors to APIToolkit
 
 APIToolkit detects a lot of API issues automatically, but it's also valuable to report and track errors. This helps you associate more details about the backend with a given failing request.
