How to add WhatsApp Chat to a OpenCart store

Embed WhatsApp Chat on OpenCart

01

Create a WhatsApp Chat extension for OpenCart on Common Ninja

First, create a OpenCart WhatsApp Chat extension on Common Ninja. On the extensions catalog, find the WhatsApp Chat and enter the Editor.

02

Save the WhatsApp Chat extension

When you're done creating the WhatsApp Chat extension, click on the Save Changes button at the right top corner of the editor. If you don't have an account on Common Ninja, you'll have to register first.

03

Copy the WhatsApp Chat Embed Code

When you're ready to add the WhatsApp Chat extension to your OpenCart store, click the Add To Website button at the top bar of the Editor. On the window that opens, click the Copy Icon to copy the extension embed code. In the next steps, you will paste this code into your OpenCart store.

04

Paste the code to your OpenCart website’s HTML field.

Next, go to your OpenCart store editor and find the HTML field. It is most likely in the form of an HTML/Code widget or module which you can find on the OpenCart’s editor. Add it to your page, and paste the WhatsApp Chat Embed Code you’ve copied before to the HTML field. Save and update, and that’s it, you should have Common Ninja’s WhatsApp Chat extension on your OpenCart store.

05

Alternative Method 1: Through the HTML option in the text’s editing area.

If you can't find the HTML/Code widget or module, there's another way to put Common Ninja’s WhatsApp Chat extension on your OpenCart extension. You can just add the code to a special HTML section in the text editor.

06

Alternative Method 2: Add it directly to your OpenCart store’s HTML code.

If you're having trouble finding a widget or a special part in your text editor where you can add the Embed Code, you can try a different way to add the WhatsApp Chat extension to your OpenCart store. You can do this by putting it straight into your OpenCart store's HTML code.

Why Use This Widget

Use the WhatsApp Chat widget when you want visitors to contact you through a channel they trust and use every day. Many buyers prefer sending a quick WhatsApp message instead of filling forms or calling, especially on mobile. This widget places a clear entry point on your pages so they can ask about pricing, availability, or product fit with a single tap. The conversation moves to WhatsApp, where you can continue in a personal, informal style that often converts better than email. It works well for local businesses, service providers, and online stores that rely on fast replies to close deals and reassure new customers.
