How to connect to Google APIs

I had small issue searching for the right way connecting to Google Cloud APIs, that’s why I want to show you how to connect with an example for Vision API, you can find that the steps are easy but I will list them.

• Create Google account and API key in https://console.developers.google.com/apis/credentials
• Enable Google Cloud Vision API or any other that you need
• Create Service account key https://console.developers.google.com/iam-admin/serviceaccounts/
• You will receive JSON file which has to be stored somewhere in the project
• Set the path to this JSON in global environment variable, with PHP is like this

  putenv('GOOGLE_APPLICATION_CREDENTIALS=' . realpath('./path-to-the-JSON-file.json'));

• Run composer require google/cloud to download Google APIs
• Then in your PHP file you can do use Google\Cloud\Vision\VisionClient or the API that you need
• Creating instance of the API

  
   $vision = new VisionClient(
              [
                  'projectId' => 'YOUR-API-KEY',
              ]
          );
