Legacy People API has not been used in project

Question

I am getting error when calling google sign in API. Error is

"Legacy People API has not been used in project ************ before or it is disabled"

But the people API is enable. How to solve this error ?

This is my google api url is this is sufficient to solve my problem

if (empty($_POST['google_key'])) {
        $error_code    = 5;
        $error_message = 'google_key (POST) is missing';
    } else {
        $app_key = $_POST['google_key'];
        // https://www.googleapis.com/plus/v1/people/me?access_token={$access_token}&key={$app_key}
        $get_user_details = fetchDataFromURL("https://people.googleapis.com/v1/people/me?access_token={$access_token}&key={$app_key}");
        $json_data = json_decode($get_user_details);
        if (!empty($json_data->error)) {
            $error_code    = 4;
            $error_message = $json_data->error;
        } else if (!empty($json_data->id)) {
            $social_id = $json_data->id;
            $social_email = $json_data->emails[0]->value;
            $social_name = $json_data->displayName;
            if (empty($social_email)) {
                $social_email = 'go_' . $social_id . '@google.com';
            }
        }
    }

this is my code where m using app key as google key and the access token now explain me where's the problem

Answer 1

The trick here is that it says legacy people api, this often means you are trying to use one of the old Google+ scopes.

A lot of the profile related endpoints that where once part of the google+ api were moved to the People api after the shutdown of Google+ .

As you can see by the endpoint you are calling you are trying to use the old google+ endpoint which was shutdown years ago.

googleapis.com/plus/v1

You should be using people.get

The correct endpoint would be.

GET https://people.googleapis.com/v1/{resourceName=people/*}

People API scopes

These are the new scopes for the people api.

Enable people api

The first thing you need to do is double check the Client id and the project you are using. Are in fact the same as the one you think it is.

Then go to Google cloud console for that project. Click library

In the search box search for people

And select people api

Then click enable

Once it has been enable in the same project as the client id you are using it should work within a few minutes.

PHP code

Assuming you are following the PHP quick start something like the following should give you the response you are looking for.

 $results = $service->people->get('people/me');
