 * `@every 15s` where `s` is seconds, `m` minutes, and `h` hours
 * `@daily` or `@hourly` which runs at that period from the time the binding is initialized
 
+## Listen to the cron binding
+
+After setting up the cron binding, all we need to do is listen on an endpoint that matches the name of our component. let's assume the <NAME> is `scheduled`. Note that this will be made as a HTTP `POST` request. The example below shows how a simple Node.js Express application can receive calls on the `/scheduled` endpoint and write a message to the console.
+  
+```js
+app.post('/scheduled', async function(req, res){
+    console.log("scheduled endpoint called", req.body)
+    res.status(200).send()
+});
+```
+  
+If we run this, we'll see that the /scheduled endpoint is called every five minutes by the Dapr sidecar.
