Make sure you have performed WooCommerce upgrade correctly to allow WooCommerce and API2Cart work with your orders properly.

There are two ways to establish WooCommerce upgrade:

1. Automated. Just press “Update Now” button and all needed changes will be done correctly.
2. Manual. Update all WooCommerce files via your FTP client. In this case, after upload, you have to click “Run Installation” in your admin panel.

After updating the WooCommerce plugin, you need to execute the cart.validate method. This is necessary because API2Cart stores store settings in the cache. The cart.validate method clears the cache for the selected store, ensuring that all changes are considered in subsequent requests.

Notice that only after that, database version is updated. Otherwise, you won’t be able to view the previously placed orders in WooCommerce itself. And API2Cart will not be able to detect new WooCommerce version, thus work with new orders.
