title: Executing Functions using the Apps Script API in PHP script with service account of Google Cloud Platform
body: <p>I am referring to these documents
  <a href="https://developers.google.com/apps-script/api/quickstart/php" rel="nofollow noreferrer">https://developers.google.com/apps-script/api/quickstart/php</a>

  for this implementation. </p>
  
  <p>These document explains examples with Auth2.0. Since I am using GCP project for this implementation, i want to use service account of my GCP project for authorization. </p>
  
  <p>I have used GCP service account to use SpreadSheet Apis and its works great. </p>
  
  <p>After brain storming I have finally got answer that : service accounts are not allowed to access the Execution API.</p>
  
  <p>I dont want to Auth method for this implementation and service account not supported by this API. </p>
  
  <p>Question: Is there any other potential way to do this. </p>
