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.

This plugin connects to the Meta WhatsApp Cloud API (a third-party service). See the “External Services” section below for full details.

Open source

Lemon Squeezy (only used if you enter a Supporter license key)

CartPinger is fully free. If you choose to support the project by buying an optional Supporter license at cartpinger.com, the plugin verifies that key against the Lemon Squeezy licensing API once you click “Activate” in CartPinger → Settings → Supporter, and again once per day to confirm it is still valid. No other data is sent. If you never enter a license key, this service is never contacted.
