 ## Deploying the reference implementation
 
 The application will show you how to manage webhooks, specifically for a SharePoint list. It also contains a reference implementation of a webhook service endpoint which you can reuse in your webhook projects.

 ## Introduction to webhooks
 
 Webhooks notify your application about changes in SharePoint that the application needs to monitor. There's no need for your application to regularly poll for changes anymore. With webhooks your application is notified (**push** model) whenever there's a change. Webhooks are not specific to Microsoft. They are a universal web standard that's also being adopted by other vendors (e.g., WordPress, GitHub, MailChimp, and others).
 
 ### Adding a webhook to your SharePoint list
 
-The reference implementation works with a SharePoint list. To add a webhook to a SharePoint list, your application first creates a webhook subscription by sending a [`POST /_api/web/lists('list-id')/subscriptions`](./create-subscription) request. The request includes the following items:

 To avoid getting the same change repeatedly, it's important that you inform SharePoint from which point you want the changes. This is done by passing a **changeToken**, which also implies that your service endpoint needs to persist the last used **changeToken** so that it can be used the next time the service endpoint is called.
