I need to use the SharePoint Rest API from a custom JavaScript application (outside from SharePoint).
How can I authenticate the user to use the Rest API.
I can not deploy a SharePoint app, I need those web services from my app.
I need to access to SharePoint on premise data.

  • I'm not convinced you can't use something like provider-hosted app. However if you want to hack around you could use a proxy. – eirikb Mar 6 '15 at 8:29
  • So is there no way to call API from outside SharePoint? – Nk SP Mar 6 '15 at 8:30
  • None of the APIs will let you do CORS AFAIK, which makes me think of using a proxy. Why can't you just use the token you get from TokenHelper in a provider-hosted app and then just route all REST requests through your provider-hosted app? I would imagine you could just pass requests – eirikb Mar 6 '15 at 8:37
  • This discussion would help you Update items using REST API from outside – Kushan L Perera Jun 14 '16 at 6:28

It appears that such a scenario is now possible: https://msdn.microsoft.com/en-us/office/office365/howto/create-web-apps-using-CORS-to-access-files-in-Office-365

How to authenticate external app

Disclaimer: I have not tested this scenario yet..

  • This is quite nice. Does it only work with Azure AD? What about "plain" 365, and on-premise? – eirikb Mar 10 '15 at 6:13
  • You will need Azure AD or ADFS (on-premise AD) to create OAuth tickets for authentication.. without this, it will not know how to issue tickets and coordinate authentication among different parties.. – Shailen Sukul Mar 11 '15 at 7:09
