404 Resource Not Found: domain with Google Directory API - ruby

Question

I followed the quick start and am attempting to create a user using the google-api-ruby-client.
I've set up access in the google api console. And I can get this to work using the API explorer.
But when I try using the ruby client, I'm getting a resource not found: domain error.
Here's the code:
def self.create_user
# Initialize the client.
client = Google::APIClient.new(
:application_name => 'MYAPP',
:application_version => '0.0.1'
)
# Authorization
# Load our credentials for the service account
key = Google::APIClient::KeyUtils.load_from_pkcs12(KEY_FILE, KEY_SECRET)
client.authorization = Signet::OAuth2::Client.new(
token_credential_uri: 'https://accounts.google.com/o/oauth2/token',
audience: 'https://accounts.google.com/o/oauth2/token',
scope: 'https://www.googleapis.com/auth/admin.directory.user',
issuer: ACCOUNT_ID,
signing_key: key)
# Request a token for our service account
client.authorization.fetch_access_token!
# Load API Methods
admin = client.discovered_api('admin', 'directory_v1')
# Make an API call.
result = client.execute(
admin.users.update,
name: { familyName: 'testy', givenName: 'testerson' },
password: '!password12345!',
primaryEmail: 'ttesterson#my-actual-domain.com'
)
result.data
end
Here's the response:
"error"=>{"errors"=>[{"domain"=>"global", "reason"=>"notFound", "message"=>"Resource Not Found: domain"}], "code"=>404, "message"=>"Resource Not Found: domain"}
Why?

After a bit of documentation reading, there were two things that I needed to fix.
I hadn't set up the proper authorization for my test service account.
You have to go to the Apps Console > Security > Advanced > Manage API client access and add the client url for your service account as well as any specific permissions that you want to add
As seen in this question, it seems that you need to create a user object rather than just passing in parameters.
Here's my updated code:
# Authorization happens here ....
api = client.discovered_api('admin', 'directory_v1')
new_user = api.users.insert.request_schema.new(
name: { familyName: 'Testy', givenName: 'Testerson' },
primaryEmail: 'ttttesterson#<domain-redacted>.com',
password: 'password123'
)
result = client.execute(
api_method: api.users.insert,
body_object: new_user
)
