Revoke access granted to my app Google Drive API - google-api

Question

How do I revoke access that has been granted to my Google Drive web application so that upon the user's next use he is asked for permissions afresh?

Answer 1

For revoking your access token, you need to "GET" (!) this url:
https://accounts.google.com/o/oauth2/revoke?token={token}
where {token} is the value of your token, as explained here:
https://developers.google.com/accounts/docs/OAuth2WebServer#tokenrevoke
For Java API (don't know for other languages), as of 9th of Sept 2012, there is no API for this.
I managed to revoke a token with this code:
class myGoogleApi {
private static final HttpTransport HTTP_TRANSPORT = new NetHttpTransport();
...
public revoke(String token) {
HttpRequestFactory factory = HTTP_TRANSPORT.createRequestFactory();
GoogleUrl url = new GoogleUrl("https://accounts.google.com/o/oauth2/revoke?token="+token);
HttpRequest request = factory.buildGetRequest(url);
HttpResponse response = request.execute();
...
}

Answer 2

If you clobbered all the refresh tokens in your DB, adding the query parameter approval_prompt=force to the auth request will fix that. It'll result in the refresh tokens getting reissued when the user next approves the request.

Answer 3

In order to revoke the access go to the below url
https://security.google.com/settings/security/permissions?pli=1
Choose your apps that you need to revoke and click on remove.

Answer 4

Visit https://accounts.google.com/b/0/IssuedAuthSubTokens?hl=en for the list of applications and sites that you granted access to. Next to each of them you'll find a Revoke Access button.
The instructions to get to that page are at http://support.google.com/accounts/bin/answer.py?hl=en&answer=41236

Answer 5

Using Google Play Services:
http://developer.android.com/reference/com/google/android/gms/auth/GoogleAuthUtil.html
Add https://www.googleapis.com/auth/userinfo.profile to your scope.
Example:
String scope="oauth2:https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile"
final String token = GoogleAuthUtil.getToken(context, "xxxx#gmail.com", scope);
OR "brute force"
Intent res = new Intent();
res.addCategory("account:xxxx#gmail.com");
res.addCategory("scope:oauth2:https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile");
res.putExtra("service", "oauth2:https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile");
Bundle extra= new Bundle();
extra.putString("androidPackageName","com.your.package");
res.putExtra("callerExtras",extra);
res.putExtra("androidPackageName","com.your.package");
res.putExtra("authAccount","xxxx#gmail.com");
String mPackage = "com.google.android.gms";
String mClass = "com.google.android.gms.auth.TokenActivity";
res.setComponent(new ComponentName(mPackage,mClass));
startActivityForResult(res,100);
Now, when you revoke the access here https://accounts.google.com/IssuedAuthSubTokens the application shows you the window for permission again in the device.
