From couple of days, I am trying to access Custom made SharePoint Online (Office 365) List for CRUD Operation with the help of Rest APIs Endpoints using Postman, but all the time I am getting "Access Denied" Response in body.
I have got OAUTH Access Token with the help of Client Id, Client Secret, & Bearer Realm Token. I am also sending Access Token in Header, also i am given FULL-CONTROL Permission level by the SharePoint Admin.
Hope you got my point. Please let me know for any further Issue clarification.
Note : List of Rest URL Endpoints I can Access are given below :
