 When you're working with the SharePoint REST service, you'll often start out knowing the URL of a specific SharePoint item, but want to access related items, such as the folder or library structure where that item resides. For example, suppose you create an add-in where your user enters the URL of a document in a SharePoint library. Your add-in must then break down that URL to figure out the actual SharePoint site URL. After it's done that, the add-in can then make more requests from the site on the user's behalf, such as to create, update, or delete related items or resources.
 
 To do this, your add-in needs to query SharePoint for the following information:

 If you want to synchronize items between SharePoint and your add-ins or services, you can use the **GetListItemChangesSinceToken** resource to do so. The **GetListItemChangesSinceToken**, part of the SharePoint REST service, corresponds to the **Lists.GetListItemChangesSinceToken** web service call.
 
 Perform a **POST** request that includes an [SP.ChangeLogItemQuery object properties](#bk_props) object in the request body.

 The code examples in this article use the REST interface and jQuery AJAX requests to add a local file to the **Documents** library, and then change properties of the list item that represents the uploaded file.
 
 This process uses the following high-level steps:
