Using the optional include parameters for the REST "List accounts" endpoint, I've been able to return additional information for "lit_guid" and "registration_settings", but nothing seems to be returned when I use the "services" parameter. I've made sure that the account I'm accessing with is an account manager, and I've tried using the root account and different sub-accounts.
The API simply states: "services" returns services and whether they are enabled (requires account management permissions)
I'm guessing that my Canvas instance doesn't have any "services" that are referenced by this parameter. What are the services that this parameter references?
