Google Service Account Private Key in JSON File

To authenticate the Google Cloud API's we need a Private Key which will be generated by Google for each Service Account Individually . This Private Key can be generated in 2 formats .

• JSON format
• PKCS12 format

Sample JSON file with Private Key:

{
 "type": "service_account",
 
 "project_id": "XXXX:api-project-1234",
 
 "private_key_id": "xxxxxx4360517xxxxx",
 
 "private_key": "-----BEGIN PRIVATE KEY-----\+lzqL6szpFDr5M/ow8Fa8X\nKokb6SfT+liJJboTVosoR8C1l1EnYRg+/qwv0w4JPdmLS1sY53k2EFP0EcqVYOYr\nDZx6a+TIVFB
