Is it possible to access Google Play Game Services API with service account?

I've created the game thru Google Play Developer Console (it is ready for testing, but not published yet).

Two service accounts are added there as testers - [email protected] (Google App Engine service account) and 64436212345-enq9gkd1abcdefghjec2kha39je5ojsc@developer.gserviceaccount.com (manually created service account, it was created before an access to Google Play Game Services API was given). First one is used for production GAE environment, second one is for development environment (run with --appidentity_email_address). Both accounts work well with Google Analytics API.

Now I try to use these accounts to work with Google Play Game Services API.

The following code is used for authorization and works fine:

credentials = AppAssertionCredentials(scope=['https://www.googleapis.com/auth/games', 'https://www.googleapis.com/auth/plus.login'])
http = credentials.authorize(httplib2.Http(memcache))

But I am getting an error when trying to access achievements definition (also tried to get application metadata - got the same issue):

response = service.achievementDefinitions().list().execute()

In development environment I get 

<HttpError 404 when requesting https://www.googleapis.com/games/v1/achievements?alt=json returned "The requested application with ID 64436212345 was not found.">

and in production:

<HttpError 500 when requesting https://www.googleapis.com/games/v1/achievements?alt=json returned "">

What is wrong there? Are service accounts supported by Google Play Services API?

Upd. Further analysis showed that 64436212345 is an ID of my GAE application, when an ID of my Google Play application is 760943112345.

So, I went to Google Developer Console for application 760943112345 and added 64436212345-enq9gkd1abcdefghjec2kha39je5ojsc@developer.gserviceaccount.com and [email protected] as the member their. It didn't help.

Then I generated new service account ID there and run GAE locally with this service account. In result, I've started to get 

<HttpError 401 when requesting https://www.googleapis.com/games/v1/applications/760943112345?alt=json returned "User has not completed registration.">

Of course, my service account doesn't have Google+ profile.

Solution

  • I am also struggling with service accounts and Google game services, and am stuck at the same point (my service account doesn't have a G+ account).

    The only indication I have found in the Google literature (supposedly Updated Jan 22, 2014) says service accounts are not supported:

    Warning: Very few Google APIs currently support Service Accounts. Service accounts are >currently supported by the following Google developer services:

    • Google Cloud Storage
    • Google Prediction API
    • Google URL Shortener
    • Google OAuth 2.0 Authorization Server
    • Google BigQuery

    This is embedded in some google api php client documentation however, so I cannot attest its validity.

    Let me know if you have any luck getting this to work and I'll do the same!
