For this example, we assume you have created a legacy transactional template in the UI or via the API. Following is the template content we used for testing.
Template ID (replace with your own):
13b8f94f-bcae-4ec6-b752-70d6cb59f932
Email Subject:
<%subject%>
Template Body:
<html>
<head>
<title></title>
</head>
<body>
Hello {{name}},
<br /><br/>
I'm glad you are trying out the template feature!
<br /><br/>
<%body%>
<br /><br/>
I hope you are having a great day in {{city}} :)
<br /><br/>
</body>

sgMail.setApiKey(process.env.SENDGRID_API_KEY);
sgMail.setSubstitutionWrappers('{{', '}}'); // Configure the substitution tag wrappers globally
const msg = {

from: '[email protected]',
subject: 'Hello world',
text: 'Hello plain world!',

templateId: '13b8f94f-bcae-4ec6-b752-70d6cb59f932',
substitutions: {

city: 'Denver',
},
};
sgMail.send(msg);Alternatively, you may specify the substitution wrappers via the msg object as well. This will override any wrappers you may have configured globally.
const msg = {
...
substitutionWrappers: ['{{', '}}'],
...
};
