Rest call to SP Online site from SP 2013 javascript code

Question

Hi All,

I have SP Online site with list and SP 2013 site. I want to access SP Online list into SP 2013 site using REST call.

Can anyone please help me how to achieve this? Please provide some sample code for the same.

Thanks,
Harish Patil

Answer 1

When we call the rest API of SharePoint online in SharePoint 2013, we need to perform identity authentication. We could use Microsoft Authentication Library (MSAL).
Official demo:Tutorial: Sign in users and call the Microsoft Graph API from a JavaScript single-page application (SPA)
Similar issue for your reference:
Unauthorized request in Sharepoint API with MSAL token
Access SharePoint Online "_api/web/..." api using the MSAL library

Or you could try to copy the list from online to 2013, and then request this rest API in 2013 directly.
