getting started with google directory API and device management

Heyy, I was looking into Google apps for business and playing with the API
explorer ... I have a reseller account with google let's say
stack@reseller.goteam.com and this works for creating users, org units,
subscriptions and so. I want to start with the device management and
investigating on these things:
1) How do I know my customerId from google cpanel ... I am looking to know
how to see the info required for these requests in CPanel.
2) I am getting the below error:
400 Bad Request
- Show headers -
{
"error": {
"errors": [
{
"domain": "global",
"reason": "badRequest",
"message": "Bad Request"
}
],
"code": 400,
"message": "Bad Request"
}
}
In my request, I entered "goteam.com" as customerId..... Isn't this
correct? any good posts on getting started with device management....
Please help
