Retrieve deleted product ID

Hello everyone,

I’m currently trying to improve the integration of one of my plugins into WooCommerce. Specifically, I’m trying to display the product name of a deleted product inside the woocommerce_after_order_itemmeta action.

I noticed that the hook passes a WC_Order_Item_Product object, and it even has a get_product_id() method, but it always returns 0 for deleted products. I happen to store the product ID in a table of my own, but if the order contains multiple different product ID’s I can’t be sure which ones belong, and which don’t.

So to keep it short: Is there any way to retrieve the product ID of a deleted WooCommerce Product?

PS: The product is in fact, deleted, not trashed!
