post - Access denied error message when trying to create a shared link to a folder in Box -

so following on previous question around permissions add collaborators, having further permissions issues when trying create shared link folder in box using api.

so confirm, have "manage enterprise" scope enabled on api account.

here error message getting back:

{"type":"error","status":403,"code":"access_denied_insufficient_permissions","help_url":"http:\/\/developers.box.com\/docs\/#errors","message":"access denied - insufficient permission","request_id":"2137493926531843e3c61af"} 

here post data sending:

{"shared_link":{"access":"collaborators"}} 

here url sending to:

https://api.box.com/2.0/folders/1561835651 

the folder id folder have created using api, , able add collaborators folder ok, until point, have correct permissions perform these operations.

so question is, else should doing? cannot see more options against account suggest need more permissions, , documentation not clear on else need able perform operation.

for createsharedlink method, http action put. if use post method, return 403 sharedlink access_denied_insufficient_permissions error. -ivy
