How To Fix Woocommerce
This guide explains the problem of how to fix woocommerce — what causes it, what to check, and when it's worth spending money to fix it.
Why This Happens
- Configuration gaps between tools or services
- Missing integrations or manual workarounds that weren't designed to scale
- Changes in vendor behavior, pricing, or API that weren't communicated clearly
What To Check First
- Verify your current setup matches the vendor's latest documentation
- Look for recent changes — platform updates, new team members, configuration drift
- Check if the problem is consistent or intermittent (different root causes, different fixes)
When To Escalate
- The problem is costing you money or customers per week
- You've spent more than 2 hours on it without progress
- A vendor quoted you more than $500 and you're not sure if it's necessary

Why is WooCommerce not working or integration failing? +
WooCommerce failures in 2026: (1) Plugin conflict — WooCommerce conflicts with poorly coded themes or other plugins. Switch to Storefront theme and disable plugins one-by-one to isolate. (2) PHP version incompatible — WooCommerce 8+ requires PHP 8.0+. Check your PHP version in WooCommerce → Status → System Status. (3) REST API authentication failing — WooCommerce REST API uses Consumer Key/Secret; verify they're generated for the correct site URL. (4) Webhooks not delivering — check WooCommerce → Settings → Advanced → Webhooks for delivery status and error logs.
How do I fix WooCommerce authentication or API errors? +
WooCommerce auth fixes: (1) 401 error — regenerate API keys at WooCommerce → Settings → Advanced → REST API. Keys are site-specific; keys from staging won't work on production. (2) HMAC signature mismatch on webhooks — WooCommerce signs webhooks with the webhook secret using HMAC-SHA256. Verify you're using the raw body (not parsed) and the correct secret from WooCommerce settings. (3) SSL required — WooCommerce REST API requires HTTPS for production API calls. (4) Make sure your site URL in WordPress Settings → General matches the URL you're calling.
How do I fix WooCommerce checkout not completing? +
WooCommerce checkout fixes: (1) Check your payment gateway settings — most checkout failures are gateway configuration issues. Test with WooCommerce's built-in 'Check payments' gateway to isolate the issue. (2) WooCommerce Stripe plugin: verify your publishable and secret keys are production keys (not test keys). (3) SSL certificate issue — checkout requires valid HTTPS. (4) JavaScript error blocking submission — check Chrome DevTools console for errors during checkout. (5) Stock management blocking — if 'Manage Stock' is enabled and inventory is 0, the product can't be purchased.
How do I connect WooCommerce to external services? +
WooCommerce integrations: (1) Stripe — use the official WooCommerce Stripe plugin from the WordPress plugin repository. (2) ShipStation/Shippo — official plugins available; connect via API key from the shipping platform. (3) Mailchimp/Klaviyo — official WooCommerce plugins sync customer data to your email platform automatically. (4) For custom integrations, use WooCommerce REST API + webhooks: set up webhooks for order.created, order.updated events and call your external API. (5) Make.com or Zapier handle 80% of WooCommerce integration needs without custom code.
