I have written a backend java application for migrating documents from IBM BOX into IBM Global Image repository (Filenet). I have read all the guides and reference docs of IBM BOX authentication methods and "working with files" or "working with users" articles but still can not clearly understand how can I organize the migration.
I have an IBM BOX authorized application with JWT authentication method (because I do not have any UI and do not have any BOX users). So as I understood from reference I have now a service user profile without an access to IBM BOX documents. If I upload documents using this account I see them and can download after. I have my own IBM BOX account that I used to create a BOX application and the owner of folder to be migrated added me as a collaborator to this folder. So, when I create a developer token (for 1 hour) and use it in my backend app I can see all the content and can work with it, but using JWT I can not. What should I do to work with my IBM BOX user's content?
