Answer 1

Here's what's working for me right now in Google Apps Script, including using a dynamic template and insertion of dynamic data for the "handlebars" in my SendGrid template:

var SENDGRID_KEY ='API_KEY';

var headers = {
  "Authorization" : "Bearer "+SENDGRID_KEY, 
  "Content-Type": "application/json" 
}

function sendEmail_1() {
  
  var body = {
      "personalizations": [
        {
          "to": [
            {
              "email": "test@test.com",
              "name": "Test Name"
            }
          ],
          "bcc": [
            {
              "email": "test@test.com"
            }
          ],
          "dynamic_template_data": 
            {
              "firstName": "Marco Polo"
            }
        }
      ],
      
      "from": 
        {
          "email": "test@test.com",
          "name": "Test Name"
        },
      
      "reply_to": {
          "email": "test@test.com"
        },
      
      "template_id":"TEMPLATE_ID" 
    }
  
  var options = {
    'method':'post',
    'headers':headers,
    'payload':JSON.stringify(body)
  }
  
  var response = UrlFetchApp.fetch("https://api.sendgrid.com/v3/mail/send",options);
}
