Basic Setup, PHP, Service account flow

[Michael Shepard]

I am attempting initial setup and testing for my project. I have installed the google-ads-php library in my project with composer, I have created a service account, and downloaded my JSON key. I have created the google_ads_php.ini. I am attempting to create the basic "GetCampaigns" utility using the example provided in the repo. when I execute from my command line I get

"PHP Fatal error:  Uncaught GuzzleHttp\Exception\ClientException: Client error: `POST https://oauth2.googleapis.com/token` resulted in a `401 Unauthorized` response:
{
  "error": "unauthorized_client",
  "error_description": "Client is unauthorized to retrieve access tokens using this  (truncated...)
 in /var/www/hydraulics/vendor/guzzlehttp/guzzle/src/Exception/RequestException.php:113"

Any help would be appreciated
