@kannantl Does the whiteboard you are trying to access belong to you / or you have permission to access it? If not, the owner may need to edit the permissions on the whiteboard before you can export it.
Hi @ojus.zoom We are also facing the same issue as i am the owner account and i am trying to access my child account’s whiteboard for export, but it says permission required. And the Server-to-Server OAuth App is also made using this account (owner account) only.
