Order via WhatsApp on Shopify product pages
A product-page WhatsApp button lets a shopper start an order conversation about the exact product and variant they are looking at. WhatsApp Pilot's Smart Product WhatsApp Button goes one step further: when the selected variant is sold out, the same button becomes a back-in-stock request.

Two actions from one button
- Variant available: the button reads Order via WhatsApp and opens an order message.
- Variant unavailable: the button reads Notify me when back in stock and opens a back-in-stock request.
- The switch follows the variant's real availability in Shopify as the shopper changes options.
Add it to your theme
- Open Theme Editor and go to the product template.
- Add the WhatsApp Product Order Button app block under Add to cart.
- Edit the button texts and opening messages in your store's language.
- Set colors, size, alignment and device visibility, then save.
Who it suits
- Stores whose customers prefer to confirm an order in a chat, common with cash on delivery.
- Products with sizes or options where shoppers ask before buying.
- Stores that sell out often and want to capture the interest instead of losing it.
