In this fast-paced world, no customer wants to actively wait for a reply to the query they ask brands. Time is becoming increasingly valuable, and due to high customer service expectations, businesses fail to cater to their customers efficiently.
But not many businesses know that they can fix this with a solution as simple as embedding a WhatsApp chat button on their website.
A step-by-step guide to set up a WordPress WhatsApp live chat
1. In your Trengo account, click on the ‘Settings’ icon in the bottom left corner, then click on the ‘Web widgets’ option.

2. Click on Website widget > Installation.

In these two steps, you’ve successfully copied the WhatsApp chat installation code to your clipboard. There are two methods of embedding WhatsApp to your WordPress website:
- Use Google Tag Manager
- Use a WordPress plugin (WPCode)
Let’s first look at how to install WhatsApp to WordPress with Google Tag Manager.
Google Tag Manager installation
1. Open your Google Tag Manager account and select the website you want to install the WhatsApp website widget.

2. Click ‘New Tag.’

3. Add a name for the WhatsApp widget.

4. After naming your widget, click on ‘Tag Configuration,’ scroll down till you see an option - ‘Custom,’ and select ‘Custom HTML.’

5. Remember the installation code you copied to your clipboard earlier? Time to paste it in the custom HTML tab.

6. Now, it's time to select which pages will have this WhatsApp widget. Select ‘All pages’ if you want the WhatsApp chat to be on every page of your website.

7. Click ‘Save.’

8. Click ‘Submit’ and Voila! Your WhatsApp chat widget is live on your website.

Adding WhatsApp chat widget on WordPress website via WPCode
1. Go to your WordPress website’s dashboard (WP Admin), click on Plugins > Add New.

2. In the search bar, type WPCode and install the first plugin that appears on the screen.

3. Click on ‘Activate.’

4. In the left-hand side menu, you will see an option called ‘Code Snippets.’ Click on it.

5. Click on ‘Add New.’

6. We have a custom code for installing the WhatsApp widget from earlier, so click on 'Add Your Custom Code.'

7. Paste the HTML code in the Code Preview window.

8. Scroll down and ensure the Location option is set to ‘Site Wide Header.’

9. Click on ‘Save Snippet,’ and your WhatsApp website widget is ready to go live.
