Keep getting a "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup" when attempting to google plus login on my web app

Question

I'm trying to implement Google plus sign up on my web app and I followed the google docs to set up the sign up however when I attempt a signup after accepting permissions and using the access token returned to me any api restcall I make returns the Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup error. I have already signed up my app with a ouath 2.0 key, so I don't seem to get what I'm doing wrong. Here is my code.

Cient Side:

const clientId = "5XXX000XX.apps.googleusercontent.com";
const apiKey = "AIzaSyCAXE5JSa36jcC*X7HV40SBcIWBiVGUTBE";
const scopes = "https://www.googleapis.com/auth/plus.login";
let accessToken = null;

function initer() {
  gapi.client.setApiKey(apiKey);
  // alert("Hello init");
  if ($("#authorize-button").length > 0) {
    $("#authorize-button").click(onLoginClick);
  }
}

function onLoginClick() {
  // $("#modalLoading").modal();
  // alert("yeah");
  gapi.auth.authorize({ client_id: clientId, scope: scopes, immediate: false }, onConnect);
}

function onConnect(authResult) {
  // alert("On connect");
  if (authResult && !authResult.error) {
    alert("Hey");
    accessToken = authResult.access_token;
    triggerLogin();
  } else {
    alert("Error");
  }
}

triggerLogin = function() {
  alert("Triggering login");
  $("#modalLoading").modal();
  $.ajax({
    url: window.config.site_root + "account/google_login",
    type: "POST",
    data: "access_token=" + accessToken,
    success: onLogin,
    error() {
      onError("Logging In", "starting your session");
    },
  });
};

onLogin = function(login) {
  alert("Login start");
  $("#modalLoading").modal("hide");
  if (login.operation) {
    location.reload();
  } else {
    alert("Register will start");
    triggerRegistration();
  }
};

triggerRegistration = function() {
  $("#modalLoading").modal();
  $.ajax({
    url: window.config.site_root + "account/google_registration",
    type: "POST",
    data: "access_token=" + accessToken,
    success: onRegistration,
    error() {
      alert("An Error");
    },
  });
};

onRegistration = function(data) {
  alert("Handling register");
  $("#modalLoading").modal("hide");
  if (data.account_exists) {
    stage.showErrorModal(
      "Account already registered",
      "There is already an account with that email address, are you sure you created an account using this login method?",
    );
  } else if (data.operation) {
    alert("Login now");
    triggerLogin();
  } else {
    alert("Error");
    onError("Registering", "creating your account");
  }
};

Here is my server side code

 public function google_registration()
            {
                $access_token = (isset($_POST["access_token"]) && !empty($_POST["access_token"])) ? $_POST["access_token"] : null;


                $name = null;
                $email = null;
                $account_id = null;
                $picture = null;
                $gender = null;

                try
                {
                    if($access_token)
                    {
                        $me = file_get_contents("https://www.googleapis.com/plus/v1/people/me?access_token=".$access_token);
                        if($me)
                        {
                            $me = json_decode($me);
                            $name = $me->name.formatted;
                            $email = $me->email;
                            $account_id = $me->id;
                            $picture = $me->image;
                            $gender = ($me->gender == "female") ? 1 : 0;
                        }
                    }
                }
                catch(Exception $error)
                {
                    // let the system handle the error quietly.
                }
                return $this->service_registration("google", $name, $email, $account_id, $picture, $gender);

            }

I too ran into the same error - "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup".

I went and checked my google developer console under APIs for the project associated with the API key/ auth key, eg, https://console.developers.google.com/project/<your app id>/apiui/api. The status for Google+API was set to OFF. I turned it ON.

I then got another access token, and then tried with the new one. It worked, ie, the error was gone and I got the profile details. To cross-check if that was indeed the cause of the error, I went back to console and disabled Google+ API. But now, I get the error:

"Access Not Configured. Please use Google Developers Console to activate the API for your project."

So, I am not 100% sure that it was the turning on/off of the Google+ API in my developer console, but do ensure that this is turned on. Also, wait a few minutes after turning on, and ensure that you get a fresh token each time before trying it.

This issue happens when you are already logged in and still try to login again and again. I faced same error so did some experiments 1) I opened website on my mobile and everything was fine. 2) Then i tried on another laptop and used different gmail account to login and it again worked fine. 3) On my first laptop i tied again by clicking "Signin" button i got same error, so i opened google.com then logged out completely and then tried again, this time it worked. So i believe, Issue is clicking login button again and again without logout.

I am not sure if this is a really a issue, but atleast this is what i found. I am still trying, trying and trying , will post if i found anything else.

Cheers !!

Make sure you have Google+ Api here enabled.

Without it you will get errors like:

"domain": "usageLimits",
"reason": "dailyLimitExceededUnreg",
"message": "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup.",

To enable it:

1) open https://console.developers.google.com

2) choose your project (top right corner)

3) search for "Google+ API" in search box and enable it if it is not enabled already.

You have to add the apiKey with the URL:

$curl = curl_init( 'https://www.googleapis.com/urlshortener/v1/url?key=AIza3834-Key' );
