You can execute APIs on service Commcell by routing the APIs from the Global Command Center URL to the target service commcell. To do this, include the CVContext=Comet and _cn headers in the API request, and execute the request from the Global Command Center. This allows you to execute APIs from a single endpoint without having to authenticate each service commcell individually.
