If the API token that was generated in Kisi is not working, the user that created the token may not have been assigned the role of Admin.
The account used to generate the API token must be assigned the role of Admin. If the account is not set as an Admin the API token that is generated will not sync to the Kisi Groups. For more information see How to create a Kisi admin.
