How can I troubleshoot WooCommerce - Zapier integration issues?

I have a WooCommerce staging site integrated with Zapier. I configured the webhook URL correctly, and the WooCommerce interface shows that the Zapier Feed is active and ready. I have submitted several test orders, which are visible in WooCommerce. However, there’s no corresponding data on the Zapier side; the usage history indicates nothing transmitted. I confirmed the webhook URL in WooCommerce matches my Zap settings, but I only see a log entry mentioning an error with an undefined function. Could someone guide me on what to check to resolve this issue?

WooCommerce version: 4.0.1
Zapier Integration version: 3.8
Zapier Plugin version: 1.9.6

When facing issues with WooCommerce and Zapier integration, one aspect to review is the server compatibility. Check if your server meets the necessary PHP version and configurations required by WooCommerce and the Zapier plugin. Also, ensure that no security plugins or firewall settings are blocking the webhook requests. It’s also beneficial to enable debug mode in WordPress to get a more detailed error log, which might give insights into any plugin conflicts or missing dependencies leading to the undefined function error. Aim to update WooCommerce, Zapier, and any associated plugins to their latest versions too.
