Getting domain installs for my Google Docs Add-on

Question

We have a Google-docs Add-on (built on Google Apps Script) for which we enabled the Google Apps Marketplace SDK - so that Google Apps Administrators could install our add-on at the domain level.

We have noticed a few domains have now installed our add-on - but I can't seem to find a way to get information on which domains have installed us. Is it even possible?

I have tried the Marketplace license API https://developers.google.com/apps-marketplace/v2/reference/ but it fails with a 403 error - Not authorized to access the application ID.

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "forbidden",
    "message": "Not authorized to access the application ID"
   }
  ],
  "code": 403,
  "message": "Not authorized to access the application ID"
 }
}

I even tried by creating a service account and accessed the API using the service account but got the same error.

Any input would be awesome.

Here's my Java (Groovy technically) code so far (the response is the json I've pasted above):

import com.google.api.client.googleapis.auth.oauth2.GoogleCredential
import com.google.api.client.googleapis.javanet.GoogleNetHttpTransport
import com.google.api.client.http.GenericUrl
import com.google.api.client.http.HttpRequest
import com.google.api.client.http.HttpRequestFactory
import com.google.api.client.http.HttpTransport
import com.google.api.client.json.JsonFactory
import com.google.api.client.json.jackson2.JacksonFactory
import org.springframework.security.access.annotation.Secured

class DataController {

    /**
     * Be sure to specify the name of your application. If the application name is {@code null} or
     * blank, the application will log a warning. Suggested format is "MyCompany-ProductName/1.0".
     */
    private static final String APPLICATION_NAME = "My app name";

    private static final String APPLICATION_ID = "12 digit project number";

    /** E-mail address of the service account. */
    private static final String SERVICE_ACCOUNT_EMAIL = "[email protected]";

    /** Global instance of the HTTP transport. */
    private static HttpTransport httpTransport;

    /** Global instance of the JSON factory. */
    private static final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();




    def getLicensedInfo() {

        try {
            try {
                httpTransport = GoogleNetHttpTransport.newTrustedTransport();



                GoogleCredential credential = new GoogleCredential.Builder().setTransport(httpTransport)
                        .setJsonFactory(JSON_FACTORY)
                        .setServiceAccountId(SERVICE_ACCOUNT_EMAIL)
                        .setServiceAccountScopes(Collections.singleton("https://www.googleapis.com/auth/appsmarketplace.license"))
                        .setServiceAccountPrivateKeyFromP12File(new File("a/valid/path/to/key.p12"))
                        .build();


                credential.refreshToken();
                String token = credential.getAccessToken();

                HttpRequestFactory requestFactory = httpTransport.createRequestFactory(credential);


                GenericUrl url = new GenericUrl("https://www.googleapis.com/appsmarket/v2/licenseNotification/"+APPLICATION_ID);

                HttpRequest request = requestFactory.buildGetRequest(url);

                com.google.api.client.http.HttpResponse response = request.execute();

                log.debug(response.parseAsString());


                return;
            } catch (IOException e) {
                System.err.println(e.getMessage());
            }
        } catch (Throwable t) {
            t.printStackTrace();
        }

    }



}

When making the request to the GAM License API you need to use the same Google Developers Console project that you used for your listing. In the case of an add-on, this is the console project associated with the script.
