Step-by-Step: Add WhatsApp Chat to Shopify Without Apps

Step 1: Create Your WhatsApp Chat Link

Use this format:

https://wa.me/<YourNumber>?text=<Pre-filledMessage>

Example:

https://wa.me/919999999999?text=Hi!%20I%20have%20a%20question%20about%20a%20product.

• ✅ Replace 919999999999 with your mobile number (with country code)

• ✅ Replace %20 with spaces if editing the message

Step 2: Add the Button to Your Shopify Store

Option A: Using the Shopify Theme Customizer

1. Go to Online Store > Themes > Customize

2. Navigate to the footer or header (or homepage section)

3. Add a Custom HTML block or a Rich Text block

4. Paste this code:

<a href="https://wa.me/919999999999?text=Hi%20there!" target="_blank">
  <img src="https://img.icons8.com/color/48/000000/whatsapp--v1.png" alt="WhatsApp Chat" style="width: 48px; height: 48px;" />
</a>

This will show a WhatsApp icon linked to your chat.

Step 3: Make the Button Sticky (Floating Button on Screen)

To make the chat icon float at the bottom right of the screen:

1. Go to Online Store > Themes > Edit Code

2. Open the theme.liquid file

3. Just before </body>, paste this:

<a href="https://wa.me/919999999999?text=Hi%20there!" target="_blank" style="position:fixed; bottom:20px; right:20px; z-index:1000;">
  <img src="https://img.icons8.com/color/48/000000/whatsapp--v1.png" alt="WhatsApp Chat" style="width: 60px; height: 60px;">
</a>

✅ Clean
✅ Fast
✅ No app needed

Optional Styling: Add Hover Effect or Animation

To make it look even better:

<style>
  .whatsapp-button:hover {
    transform: scale(1.1);
    transition: 0.2s ease-in-out;
  }
</style>
<a href="https://wa.me/919999999999?text=Hi%20there!" target="_blank" class="whatsapp-button" style="position:fixed; bottom:20px; right:20px; z-index:1000;">
  <img src="https://img.icons8.com/color/60/000000/whatsapp--v1.png" alt="WhatsApp Chat" />
</a>

Bonus: Add WhatsApp Link to Your Product Page

If you want users to ask questions from specific products:

<a href="https://wa.me/919999999999?text=Hi! I have a question about {{ product.title }}" target="_blank">
  Chat on WhatsApp about this product
</a>

Dynamic, product-specific messaging!
