Add Facebook Customer Chat in WordPress without Plugin

If you want to add customer chat to a WordPress website without any plugin then it is easier to implement.

Note: Here, without a plugin means without an official messenger chat box plugin.

Before everything, you have to get the Messenger Chat box code first.

Add Messenger to your website
  • Go to your Facebook Page.
  • Now, go to Facebook Page Settings > Messaging Option.
  • You can now see Add Messenger to your website.
  • Click on Get Started.
  • Now click on Setup, on step 3 copy the code.
  • Furthermore, set up everything as your need including Welcome Message, FAQs.
  • Now, Click on Publish Button.

The code looks something like this

<!-- Messenger Chat Plugin Code -->
    <div id="fb-root"></div>
        window.fbAsyncInit = function() {
            xfbml            : true,
            version          : 'v10.0'

        (function(d, s, id) {
          var js, fjs = d.getElementsByTagName(s)[0];
          if (d.getElementById(id)) return;
          js = d.createElement(s); = id;
          js.src = '';
          fjs.parentNode.insertBefore(js, fjs);
        }(document, 'script', 'facebook-jssdk'));

      <!-- Your Chat Plugin code -->
      <div class="fb-customerchat"

Now, you can paste your messenger code to your site footer.

Nowadays, most of the themes provide placement to insert script in header, body, and footer. If you are using these kinds of themes then you don’t have to add an additional plugin.

For Genesis Theme:

Go to your Dashboard > Genesis > Theme Settings > Footer scripts box and paste the code.

For Astra Theme:

  • For Astra Pro User, Go to Astra options inside Appearance and Enable Custom Layouts Module
  • Go to Appearance > Custom Layouts.
  • Click on Add New and paste your code.
  • Now go to Custom Layout Settings.
  • On Layout Choose a Hook and on Action Choose wp_footer.
  • Now On Display On Choose Entire Website.
  • Hit Publish Button.

If your theme doesn’t have the above-inbuilt features then you can add Insert Headers and Footers plugin. After installing, Go to Settings > Insert Headers and Footers. Place the messenger code in the Footer section and Hit Save.

Add Facebook Customer Chat in GeneratePress

If you are GeneratePress WordPress Premium Theme users then it is easier to insert chatbox code.

First Activate the Elements Module, for that go to Appearance > GeneratePress and Click on Activate to the Elements Module.
