Create a new service account

If necessary, you can create a new service account. For example, you might not want to use the default account for security reasons. In doing so, follow the steps below:

Step 1. You must have an active Google account.

Step 2. Using this account, open the setup tool.

Step 3. Click Create a project and select API Project.

Step 4. Click Go to credentials.

Step 5. Select the following parameters:

Step 6. Click What credentials do I need?.

Step 7. Enter the service account name and click Continue.

Step 8. The account will be created, and a JSON file with account details will be downloaded to your local hard drive. 

Please keep it in a safe place as it will be needed later.

The downloaded JSON will look similar to the code below:

{
  "type": "service_account",
  "project_id": "id",
  "private_key_id": "key_id",
  "private_key": "-----BEGIN PRIVATE KEY-----\key\n-----END PRIVATE KEY-----\n",
  "client_email": "service account email",
  "client_id": "client id",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "token_uri": "https://accounts.google.com/o/oauth2/token",
  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/etl-framework%40service-account@email"
}

The important part is the service account email.
