Trigger sendgrid template email using meteor

Question

I am using sendgrid to send an email. I want to send template as an email to users. Below code is just sending the simple text based email instead of defining the headers part and using the template id.

Click to copy

if (Meteor.isServer) {
    Email.send({
        from: "from@mailinator.com",
        to: "abc@mail.com",
        subject: "Subject",
        text: "Here is some text",
        headers: {"X-SMTPAPI": {
            "filters" : {
                "template" : {
                    "settings" : {
                        "enable" : 1,
                        "Content-Type" : "text/html",
                        "template_id": "3fca3640-b47a-4f65-8693-1ba705b9e70e"
                    }
                }
            }
        }
        }



    });
}

Your help will highly be appreciated.

Answer 1

To send SendGrid transactional templates you have different options

1) Via the SendGrid SMPT API

In this case we can use Meteor email package (as you were trying).

To add meteor email package we need to type in the sell:

Click to copy

meteor add email

In this case, according to SendGrid docs:

The text property is substituted into the <%body%> of the text template and html is substituted into the <%body%> of the HTML template. If the text property is present, but not html, then the resulting email will only contain the text version of the template, not the HTML version.

So in your code you need to provide http property too, that's all.

This could be your server code:

Click to copy

// Send via the SendGrid SMTP API, using meteor email package
Email.send({
  from: Meteor.settings.sendgrid.sender_email,
  to: userEmail,
  subject: "your template subject here",
  text: "template plain text here",
  html: "template body content here",
  headers: {
    'X-SMTPAPI': {
      "filters": {
        "templates": {
          "settings": {
            "enable": 1,
            "template_id": 'c040acdc-f938-422a-bf67-044f85f5aa03'
          }
        }
      }
    }
  }
});

2) Via the SendGrid Web API v3

You can use meteor http package to use SendGrid Web API v3 (here docs). In this case we can use the Meteor http package.

To add Meteor http package type in the shell:

Click to copy

meteor add http

Then in your server code you can use

Click to copy

// Send via the SendGrid Web API v3, using meteor http package
var endpoint, options, result;

endpoint = 'https://api.sendgrid.com/v3/mail/send';

options = {
  headers: {
    "Authorization": `Bearer ${Meteor.settings.sendgrid.api_key}`,
    "Content-Type": "application/json"
  },
  data: {
    personalizations: [
      {
        to: [
          {
            email: userEmail
          }
        ],
        subject: 'the template subject'
      }
    ],
    from: {
      email: Meteor.settings.sendgrid.sender_email
    },
    content: [
      {
        type: "text/html",
        value: "your body content here"
      }
    ],
    template_id: 'c040acdc-f938-422a-bf67-044f85f5aa03'
  }
};

result = HTTP.post(endpoint, options);
