Broken Checkout & Cart Patch
Emergency troubleshooting of failing WooCommerce, Shopify, or custom Stripe/PayPal checkouts, API response delays, card verification timeouts, and webhook notification mismatches.
Execution SOP & Action Plan
Every emergency intervention follows a strict sequence of diagnostics, mitigation checkpoints, and verification tasks to guarantee stability and prevent regressions:
1. Checkout Flow Audit
Reproduce failure in staging with browser DevTools Network tab; capture failing API requests, Stripe/PayPal error codes, and JS console errors.
2. Webhook & API Key Verification
Validate Stripe webhook secret in dashboard; test webhook delivery via Stripe CLI; confirm API keys match between .env and payment dashboard.
3. Cart Logic & Session Fix
Debug WooCommerce session handler, Shopify AJAX cart endpoint, or custom PHP cart logic; fix nonce mismatches, CORS headers, or CSRF token errors.
4. Live Payment Test & Monitoring
Run end-to-end test purchase with Stripe test card 4242 4242 4242 4242; confirm order created in CMS + webhook received; enable Stripe Radar monitoring.
