WAButton is a tool that allows website owners to add a floating button connecting visitors directly to a WhatsApp chat. Its primary function is to enable visitors to send messages from the website, with replies handled through the standard WhatsApp application on the user’s phone. The button can be customised in terms of colour, label, icon, position (either bottom corner), and greeting message. A live preview updates as selections are made, showing how the button will appear on both desktop and mobile devices. The service offers a range of features depending on the plan. On the free tier, users can add a basic button and greeting without needing a credit card. Paid plans (Starter and above) introduce support for multiple team contacts, allowing messages to be routed to different departments or individuals. The Pro plan adds custom lead capture forms that appear before WhatsApp opens, with submitted data saved in a dashboard and available for deletion. The tool also supports integration via a single line of code and works with platforms such as WooCommerce, WordPress, Magento, Adobe Commerce, Google Tag Manager, and Squarespace. A typical workflow involves a visitor landing on a website, seeing the WhatsApp button, tapping it, and sending a message. The website owner replies from within the WhatsApp app they already use. The conversation remains accessible to the visitor even after leaving the website. WAButton does not provide a shared chat inbox or booking confirmation; its scope is limited to the button and related messaging features. To install the button, users need access to their website’s code settings or assistance from someone who manages the site. A setup guide is provided, and a pre-signup preview is available to test the button’s appearance and behaviour.
