OnyxFlo Watchdog quietly monitors your WooCommerce orders in the background and takes snapshots at key points in the order lifecycle (checkout, thank you page, and status changes). It then compares those snapshots to detect suspicious changes or data inconsistencies.
OnyxFlo Watchdog uses a lightweight custom database table (<code>{prefix}onyxflo_watchdog_snapshots</code>) to store order snapshots. Uninstalling the plugin does not automatically delete existing snapshot data, so you can retain a historical audit log if needed.
Examples of what OnyxFlo Watchdog can help catch:
<ul>
<li>Orders where the cart or subtotal has changed between checkout and payment.</li>
<li>Orders that have been modified after payment but before fulfillment.</li>
<li>Data mismatches caused by buggy plugins, imports, or external integrations.</li>
</ul>
When a potential issue is found:
<ul>
<li>The order is changed to a custom status: Watchdog Flagged.</li>
<li>A clear warning notice appears on the order screen in wp-admin.</li>
<li>(Optional) An email alert can be sent to a configured address.</li>
<li>A snapshot history is stored so you can see what changed and when.</li>
</ul>
This plugin is aimed at stores that care about data integrity and want an extra layer of safety before orders are shipped or refunded.

Works great, people are just dumb

This plugin used to be one of the best tools out there, however, it seems like is not being maintained anymore. 

There is no support for the recent releases of PHP (8.0, 8.1). Recent support requests are not being handled anymore as well.



Abandoned.
