So I have master brand's API username and key, so I can user the SoftLayer_Account API to get a list of accounts it owns (i.e. the customers). With the account ID of these customer accounts, I would think that I should be able to get its own users and get their API username and key, but I don't see a way. How do I get my customer account's API username and key by using SoftLayer APIs?
I've tried using SoftLayer_Account::getUsers() but it always gives this master user info and not the customer account's users. And I don't see any other APIs that I can use. Please help.
Basically what I want to do is to get a list of all billing items that are associated with all the accounts that are under this master brand account.
