Sporadic Success Using Khoros API

Hi,

I have created an automated process to update labels on our Community. I get an authentication token with no issues and use our API url https://community.ourcommunity.com/restapi/v1/messages/id/10289/edit and send the new labels comma separated through the payload.

The strange thing is that only a handful of updates come back with success and most come back with Permission Denied and a 303 error. I have seen others mention the area and that had to do with permissions, but I'm using an admin user who has all the permissions and can produce a authentication key, so I know that is not the issue.

I have not been able to find a reason for the error as all of the calls are exactly the same other than the message ID and the labels being sent. 

Any advice on how to resolve this issue is greatly appreciated.
