Unable to use Tempo Box Sharing API v1

Hello:
I'm trying to use the "Tempo Box Sharing API v1" but I'm unable to provide the right credentials.
I've tried to use different tokens, obtained from the "AppWorks Gateway API v2" and "Content Server REST API for Content Server" auth methods, in the cstoken parameter, otagtoken Cookie and OTCSTICKET header with no luck.
Where could I obtain the cstoken parameter or what Cookie or header should I use?
Thanks in advance.
