Email Settings API - ClientLogin

Question

We are using EMAIL Settings API and ClientLogin for Authentication. EMAIL Settings API is still on GDATA Libraries. Using GDATA libraries can we start using OAuth 2.0 ? (we are using the appsforyourdomain client library to use EMAIL Settings API) Or can we continue using ClientLogin ? Based on the post looks like ClientLogin is going to retire by April 20, 2015. Please guide me the right approach. GDATA API : 1.46.0. EMAIL Settings API is used only for disabling the webclips for the user.

Eventhough EMAIL settings API is on GDATA libraries, you can use oauth 2.0. For example, contacts API is on GDATA but still it supports oauth 2.0 — SGC
Thanks SGC. Do you have any samples or link that might help me in implementing the same for Google Email settings API. I recently did Service account based Oauth 2.0 for ADMIN Directory API for user management. — user4390766

We were using GDATA API 1.46.0 and it does not support OAuth 2.0 . Support was added in 1.47.0 version. See the release note below. After using the new Libraries I was able to implement OAuth 2.0. Used GmailSettingsService class inside the appsforyourdomain client library and commented out the ClientLogin flow and added new flow for OAuth2.0. Use GoogleCredential Object to create the OAuth2.0 credential object.

//  Client Login
//  this.setUserCredentials(username + "@" + domain, password);

//  OAuth 2.0
this.setOAuth2Credentials(initCredential());

public static GoogleCredential initCredential() throws GeneralSecurityException, IOException {
      httpTransport = GoogleNetHttpTransport.newTrustedTransport();

    List<String> scopes = Arrays.asList("https://apps-apis.google.com/a/feeds/emailsettings/2.0/");

    credential = new GoogleCredential.Builder()
        .setTransport(httpTransport)
        .setJsonFactory(JSON_FACTORY)
        .setServiceAccountId(SERVICE_ACCOUNT_EMAIL)
        .setServiceAccountScopes(scopes)
        .setServiceAccountPrivateKeyFromP12File(new File(SERVICE_ACCOUNT_PKCS12_FILE_PATH))
        .setServiceAccountUser(DOMAIN_ADMIN_API_USER)
        .build();  
    return credential;
  }
