Send emails using Sendgrid with google appscript

Question

I am creating a googlesheet addon to send mails.And for sending mails I am using sendgrid. I cannot find any documentation or example code for sending mails with Google Appscript. This is the code I am using, but it is no good.

var data = {

        "api_user":"username",
        "api_key":"ioioi",
        "to":[],
        "tonnage":[],
        "cc":[],
        "ccname":[],
        "bcc":[],
        "subject":sub,
        "from":from,
        "html":htmlBody
      }

      var headers = { "Accept":"application/json", 
                     "Content-Type":"application/json"
                    };



        data = JSON.stringify(data);

        var options = {
          "method": "POST",
          "payload": data,
          "headers": headers,
          "muteHttpExceptions": true
        };

var res = UrlFetchApp.fetch("https://api.sendgrid.com/api/mail.send.json", options);

Does anyone have any idea or code to send emails with sendgrid using googl appscript?

Answer 1

Try the below code. It worked for me

   var SENDGRID_KEY ='Your API KEY';

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

  var body =
  {
  "personalizations": [
    {
      "to": [
        {
          "email": "email id of the sender"
        }
      ],
      "subject": "Hello, World!"
    }
  ],
  "from": {
    "email": "From email id"
  },
  "content": [
    {
      "type": "text",
      "value": "Hello, World!"
    }
  ]
}

  var options = {

    'method':'post',
    'headers':headers,
    'payload':JSON.stringify(body)


  }


 var response = UrlFetchApp.fetch("https://api.sendgrid.com/v3/mail/send",options);


 Logger.log(response); 

Also ensure that the API key you created in SendGrid has the all the credentials it needs to send the email
