Our Zonos checkout plugin did not have the Certificate in its keystore and could not validate the certificate for any calls being made to the Shopify API. ‌ **What was the resolution of the problem and steps that are being taken for continued follow-up?** The node version of the Zonos Checkout plugin was updated to a more current version which contained the Intermediate Certificate. After the plugin was updated we continued to monitor the incident to validate the solution corrected the issue.
