Get Folder Item ID using REST API in SharePoint

This code snippet helps you to get the list item id the folder in SharePoint document library.

I have come across some people asking for retrieving the item id of Folder based on the folder url.

In this code, I 'm going to show you simple url used to retrieve that ID,

http://sharepointsite/_api/web/GetFolderByServerRelativeUrl('/Library/Folder')/listitemallfields/id

ListItemAllFields - Returns the list item properties of the folder item.

If you want to use the REST API in Add-in development, I have just changed the hardcoded value from the url,

var folder id  = _spPageContextInfo.webAbsoluteUrl + "/_api/web/GetFolderByServerRelativeUrl('" + ctx.rootFolder + "')/listitemallfields/id";
