I used SharePoint 365 and I tried to get an item from the SharePoint list by the postman.
I am the steps in these links:
but did not work, I got an answer Access denied and sometimes 403 forbidden.
and i tried to register app & graph API in azure but i had the same result.
I want to clear the way to get the right access token.
and another question what can I put in Redirect URI? https: // localhost or my main link page
