This plugin provides a seamless checkout experience for stablecoin transactions ( USDT). #### Key Features * **Secure Crypto Payments**: Integration with the ApoloPay SDK for high-security digital asset transactions. * **WooCommerce Blocks Support**: Fully compatible with the modern WooCommerce Checkout and Cart blocks. * **Real-time Notifications**: Webhook support to ensure order statuses are updated instantly upon payment confirmation. * **Race-condition safe**: Handles edge cases where the ApoloPay webhook arrives before WooCommerce finishes creating the order. ### External Services This plugin communicates with the following external services. No personal customer data (name, address, email) is sent to any of them unless explicitly noted. #### ApoloPay Payment API Used to create payment sessions (preorders) when a customer initiates checkout. * **Data sent**: Payment amount and an optional order metadata object. * **When**: When the customer clicks “Place Order” on the checkout page. * **Endpoint**: `https://pb-api.apolopay.app` * **Privacy Policy**: https://apolopay.app/privacy * **Terms of Service**: https://apolopay.app/terms #### ApoloPay WebSocket (real-time payment status) The ApoloPay SDK opens a WebSocket connection to the ApoloPay servers to receive real-time payment confirmation events. The SDK uses the Socket.IO client library internally; the connection goes to ApoloPay’s own servers, not to socket.io.com. * **Data sent**: The payment process ID, used to subscribe to status updates for that specific payment session. * **When**: During an active payment session on the checkout page. * **Provider**: ApoloPay * **Privacy Policy**: https://apolopay.app/privacy * **Terms of Service**: https://apolopay.app/terms #### QR Code Generation (api.qrserver.com by goQR.me) The ApoloPay SDK generates a QR code so that customers can scan the recipient crypto wallet address with a mobile wallet app. The QR image is requested from api.qrserver. com directly from the customer’s browser. * **Data sent**: The cryptocurrency wallet address (a public blockchain identifier— not linked to any personal user data). * **When**: When the customer is shown the payment screen during checkout. * **Provider**: goQR.me (api.qrserver.com) * **API Documentation**: https://goqr.me/api/ * **Privacy & Security**: https://goqr.me/privacy-safety-security/ * **Legal Notice**: https://goqr.me/legal/ ## Installation 1.
