WooCommerce The payment was successful, but the order shows failed/pending payment, what is the reason?

Usually it's not that the payment didn't work, but that the callback (webhook) didn't write back the order status. Troubleshooting steps: WooCommerce → Status → Logs: see if the payment gateway has webhook error / signature error / timeout Check if the site is blocked by WAF (Cloudflare, Pagoda Firewall, security plugins) Check if "Cache checkout pages/interface paths" is enabled (checkout pages and callback interfaces should not be cached) Look at the server error logs for 500/fatal errors that interrupt the callback execution. Solution: Release wp-json, wc-api, payment gateway callback URLs (configure as per gateway documentation) Disable cache and JS merge compression test on checkout page once If using Cloudflare: set no-challenge, no-block rules for callback URLs
