Good afternoon,
I'd like to know how to use the Sharepoint Online REST API through external applications, specifically a local HTML with JS.
Using the example of this article link , I get the following error msg:
XMLHttpRequest can not load link . Response to preflight request does not pass access control check: In 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.
Thank you.
