and getting following error:

{"type":"error","status":403,"code":"access_denied_insufficient_permissions","help_url":"http:\/\/developers.box.com\/docs\/#errors","message":"access denied - insufficient permission","request_id":"11155318795551a7373138a"}  

i same error "delete" folder command in curl.

can please me this?

i believe issue quote escaping. also, have -d "....' (note mismatched " , '

try following commands box api: (don't forget add folder id & access token)

update folders

curl https://api.box.com/2.0/folders/folder_id -h "authorization: bearer access_token" -d '{"name":"new folder name!"}' -x put 

delete folders

curl https://api.box.com/2.0/folders/folder_id?recursive=true -h "authorization: bearer access_token" -x delete
