CartPinger

CartPinger connects your WooCommerce store to the official Meta WhatsApp Cloud API so you can reach customers where they actually read messages. Abandoned cart recovery — CartPinger automatically detects when a customer leaves without completing checkout and sends them a WhatsApp reminder with a direct link back to their cart. No email. No spam folder. Order notifications — Send automatic WhatsApp messages when an order is placed, paid, shipped, or completed. Customers stay informed without you lifting a finger. WhatsApp chat widget — Add a click-to-chat button to your storefront so customers can reach you instantly on WhatsApp. Bring your own account — CartPinger uses the official Meta WhatsApp Cloud API. You connect your own WhatsApp Business number. No middleman, no per-message fees beyond Meta's standard rates. Block and classic checkout — Works with both the WooCommerce block checkout (WooCommerce 8.6+) and the classic shortcode checkout. Features

• Abandoned cart recovery via WhatsApp — unlimited
• Optional 24h and 48h follow-up messages (configurable in settings)
• Optional automatic discount coupons in follow-ups (configurable)
• Order notifications on Processing, Completed, and Cancelled
• WhatsApp click-to-chat widget for the storefront
• CSV export of all abandonment and recovery data
• Works with both classic and block checkout

How it works

1. A customer adds items to their cart and starts checkout
2. They enter their phone number and check the WhatsApp consent checkbox
3. If they leave without completing the order, CartPinger waits 1 hour and sends a recovery message via WhatsApp
4. The message includes their name and a direct link back to their cart
5. If they complete the order, the recovery is marked as successful

Privacy and data CartPinger does not collect or transmit any data to servers operated by the plugin author. Customer phone numbers and message content are sent directly from your server to Meta (WhatsApp Cloud API) using your own access token. All data is stored in your own WordPress database.
