CartSignal: WhatsApp Button

CartSignal adds a floating WhatsApp button to your store that lets shoppers message you in one tap. The button works on every page, both mobile and desktop, and opens WhatsApp or WhatsApp Business with your custom message already typed in. On computers, it opens WhatsApp Web automatically. Set up your WhatsApp number, pre-filled message, button color, and position through a simple form with a live preview. Your app home shows whether the button is live and tracks how often customers tap it. The button loads no external scripts, sets no cookies, and stores no customer data—it simply links directly to WhatsApp. Give your shoppers a direct line to reach you with guided setup and complete control over how the WhatsApp chat button appears on your storefront.
