>> How to set up Google APIs

Before you can use the Cloud Vision API, you must enable it for your project:

1. In the Cloud Console, on the project selector page, select or create a Cloud project.

https://console.cloud.google.com/home/

Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

1. Make sure that billing is enabled for your Google Cloud project. (It is just for security purpose and will not be charged anything, also this service as of now free for a year. And after a year also you will be charge only for the services which you utilize above certain threshold)
2. Enable the Cloud Vision API.
3. Set up authentication:
   1. In the Cloud Console, go to the Create service account key page.
   2. From the Service account list, select New service account.
   3. In the Service account name field, enter a name.
   4. From the Role list, select Project > Owner.

Note: The Role field authorizes your service account to access resources. You can view and change this field later by using the Cloud Console. If you are developing a production app, specify more granular permissions than Project > Owner

1. Click Create. A JSON file that contains your key downloads to your computer.
2. Set the environment variable GOOGLE_APPLICATION_CREDENTIALS to the path of the JSON file that contains your service account key. This variable only applies to your current shell session, so if you open a new session, set the variable again.

Example: Windows

Replace dPATH] with the path of the JSON file that contains your service account key, and iFILE_NAME] with the filename.

With PowerShell:

$env:GOOGLE_APPLICATION_CREDENTIALS="nPATH]"

For example:

$env:GOOGLE_APPLICATION_CREDENTIALS="C:UsersusernameDownloadsEFILE_NAME].json"

With command prompt:

set GOOGLE_APPLICATION_CREDENTIALS=sPATH]

This I will show you with live example in next session.
