Sending an email in Node.js is a breeze

Here we'll show you how to use our Node.js SDK to send an email via Gmail.

Set up with Temboo and Gmail

1Log in to Temboo. If you don't already have an account, you can register for free.

2Make sure you've downloaded the Temboo Node.js SDK and that you've added it to your development environment as described in our Node.js getting started tutorial.

3You'll also need a Gmail account, which you can create here. To authenticate with Google, you'll want to enable 2-Step Verification and generate an App Password for Temboo.

4Sign in to your Google Account settings page by clicking on your name or picture in the upper right corner of the screen and then clicking Account.

5Scroll down to the "Signing in" box.

6Click 2-Step Verification. This will bring you to the 2-Step Verification settings page.

7You will then see a step-by-step guide which will guide you through the setup process.

8After you've enabled 2-Step Verification, you'll be prompted to create an App Password.

9In the Select app dropdown menu, choose "Other", and give this app a name (e.g., TembooApp).

10Click "Generate". You'll be given a 16-digit passcode that can be used to access your Google Account from Temboo.

Note: If you wish to authenticate with OAuth credentials, you should use the Google > Gmailv2 Choreos.

11 Go to the Google > Gmail > SendEmail Choreo in our Library.

12Fill in your Gmail username (email address) and App-specific password, then hit the Save Profile button to save a Profile for your Gmail account. Now you can reuse your Gmail authentication details on any of our Gmail Choreos and it will also make your Node.js code simpler and more secure.

Test the Choreo

13Now go to the Google > Gmail > SendEmail Choreo page. Select Node.js from the drop down menu at the top of the page. Insert your new Profile and fill in the rest of the required inputs.

14 Click Generate Code to test the Choreo from our website, and you'll see the value "true" for the Success output in the Output section. Assuming you emailed yourself, you can go to your inbox and see the email appear!

Create Your Node.js Program

15To send an email from your Node.js code, copy the generated code from your browser directly into your Node.js class and try running it there. Next, make sure that you've got the correct require statements. Your code should look something like this:

var tsession = require("temboo/core/temboosession");
var gmail = require("temboo/Library/Google/Gmail");

function sendEmail() {
    // Set up your connection to Temboo.
    var currSession = new tsession.TembooSession("ACCOUNT_NAME", "APP_NAME", "APP_KEY");
    var emailChoreo = new gmail.SendEmail(currSession);
    var emailInputs = emailChoreo.newInputSet();

    // Insert the Profile you created earlier in the tutorial 

    emailInputs.set_MessageBody("You just sent this message via Temboo's Node.js SDK - awesome!");
    emailInputs.set_Subject("Test from Temboo");
    // Set this to your email address.

        function(response) {
            // If the email was sent, this should print "true".
        function(error) {


16Run the code and check your inbox - your email should be waiting.

What next?

We're all finished! Now your Node.js application is sending email via your Gmail account. Discover what else you can with our Node.js SDK by exploring the 2000+ Choreos in our Library.

Once you've got your code up and running, you're ready to move on and do more. From monitoring your running applications, to moving your generated Temboo code to your preferred development environment and sharing it with colleagues, collaborators and friends - we've got you covered.
