Restoring a WooCommerce integration blocked by security controls
The storefront appeared healthy to ordinary visitors, but a third-party commerce integration could not complete its automated requests. Gotekky traced the HTTP 406 responses to the web application security layer and corrected the precise path without broadly disabling protection.
Client profile
An online retailer using WooCommerce and an external fulfilment or commerce service.
The challenge
The website worked, but the business workflow did not.
Normal page views did not reveal the problem. Automated POST requests used by the commerce integration were rejected before WordPress could process them, leaving the storefront visible while an important operational workflow remained broken.
An initial exception for the WordPress REST API did not cover a separate WooCommerce entry point. The two request paths looked related from a business perspective, but they were evaluated differently by the security layer.
Architecture and technical path
Request path and failure point
The important distinction was that the request was rejected by the security layer before it reached the application.
Gotekky response
The fix preserved security by narrowing the exception.
Reproduce the failing requests
Controlled tests separated normal browsing from the specific methods and endpoints used by the integration.
Correlate security logs
The request timing, endpoint and response were compared with web application firewall events to confirm that the rejection occurred before PHP.
Distinguish application entry points
The WordPress REST API and the WooCommerce API mechanism were treated as separate paths instead of assuming one exception covered both.
Apply a narrow exception
Only the required path and request pattern were exempted. The wider security policy remained active for the rest of the site.
Retest the complete workflow
The integration was tested again after remediation to confirm that legitimate requests reached WooCommerce successfully.
Validation
The result was verified at the application boundary.
Validation did not stop when the HTTP 406 disappeared. The test confirmed that the request passed the security layer and reached the intended WooCommerce handler.
The broader web application firewall remained enabled, avoiding the common but unsafe shortcut of disabling protection for the entire domain.
What this demonstrates
Security and application functionality are not opposing goals when the failure is investigated precisely. The correct response was to identify the exact boundary, apply the smallest necessary change and validate the business workflow end to end.
