I have files in a document library which needs to be checkout by some automatic scripts from other web application(Asp.net/javascript) using SharePoint REST API. I'm working on Sharepoint Server 2013 On Premise

I found that we can achieve it only in

  1. Sharepoint Apps
  2. SharePoint Server Project

I gone through this links

  1. https://msdn.microsoft.com/en-us/library/office/jj164022.aspx#ClientAPIs
  2. https://msdn.microsoft.com/en-us/library/office/dn292553.aspx

Is it Possible?

  • What exactly is the problem? You don't know REST endpoint for check-out, or how to make REST call between two web applications? – dstarkowski Mar 3 '16 at 8:54

    // needed to use the SharePoint object model

ClientContext ctx = new ClientContext("http://sitename");

//get the home page
File home = ctx.Web.GetFileByServerRelativeUrl("/SitePages/home.aspx");

  • what will be hostweburl & appweburl – Rakesh Sadhula Mar 3 '16 at 10:23
  • When the App first launches, SharePoint provides three values in the query string named: SPHostUrl, SPAppWebUrl and SPLanguage. – Tiago Duarte Mar 3 '16 at 10:40
  • I don't want in Sharepoint App, can I run above script in basic html with javascript ? – Rakesh Sadhula Mar 3 '16 at 10:51
  • you can use apps, CSOM, JS, C#, just choose your flavor – Tiago Duarte Mar 3 '16 at 10:59
  • if you want to run automatic scripts form an external location, I would recommend a c# console application using the client object model – Tiago Duarte Mar 3 '16 at 11:04
