Hi @Nishant Khandelwal ,
Per my test, the Permission Request XML in the article is incomplete. The correct XML should be like following
<AppPermissionRequests AllowAppOnlyPolicy="true"> <AppPermissionRequest Scope="http://sharepoint/content/sitecollection" Right="FullControl" /> </AppPermissionRequests>
You could recreate a sharepoint app only with the correct XML. And set the request like following
POST https://xxxx.sharepoint.com/sites/xxxxx/\_api/web/folders Authorization: "Bearer " + accessToken Accept: "application/json;odata=verbose" Content-Type: "application/json;odata=verbose"
The body should be like this
In your case, you are missing the listname in ServerRelativeUrl.
