I want to create one SharePoint Hosted App. In this app i have to access other SharePoint intranet site's list data, this site is in different web application. My apps site url is http://appssite.mycompany.com and web application where i want to access data is http://intranet.mycompany.com. Both this sites exist on different web applications.

I want the way, we can access other SharePoint web (not hosted web) data using CSOM in SharePoint Hosted apps.

If both the sites are not in the same tenancy or web application, then a SharePoint-hosted app cannot get data from the other site. This is by design. It is for security reasons to block cross-domain scripting attacks. You will need to use a SharePoint provider-hosted app or a SharePoint autohosted app.

Access denied, from an app, when getting List items from a different web applcation

Using JSOM or REST get list items stored in a different web application

  • Thanks Anchal! If this is true then it's bad news for me because we lots of site like leave mgmt, room booking, cab booking etc on other web applications.
