"It's a WooCommerce Problem"

A merchant uses a third-party plugin, something breaks, and the developer says “that’s a WooCommerce issue.” Sometimes true. Usually not.

The boundary: WooCommerce provides products, orders, coupons, shipping, tax, checkout, and the REST API. If the issue is with how a third-party plugin uses those systems, that’s the plugin developer’s responsibility. WooCommerce is a platform — the integration is the plugin developer’s job.

The test: Does the issue exist with only WooCommerce active? If not, it’s not WooCommerce’s problem. If the plugin developer insists, ask them to submit a detailed report to the WooCommerce GitHub repository.

For POD plugins (Printful, Printify): these connect to external APIs, sync data, and handle fulfillment through their own services. If sync fails or orders don’t pass through, that’s their integration.

General integration troubleshooting: Check Tools → Site Health. Clear WooCommerce transients (WooCommerce → Status → Tools). Verify WooCommerce is current. For API-heavy plugins, ensure PHP memory is at least 512MB and time limit is 120+. Disconnect/reconnect the integration. Check WooCommerce → Status → Logs for fatal errors.
