updateTask Zoho Connect API

updateTask Zoho Connect API

When I do POST request by https://connect.zoho.com/pulse/api/updateTask with parameters scopeID, taskId, title, status and with header Zoho-oauthtoken, I got next response:
{'updateTask': {'reason': 'You are not authorized to do this action.',
                         'result': 'failure'}}
I do this request after create task with API, and I not use streamId (I get taskId in json-format response by "addTask" -> "stream" -> "task" -> "id"), I have access to board, in board settings set that everyone can edit task. Because this request not working?
