You can use woocommerce_thankyou hook to get the product ID's in thankyou page

function wh_getProductIds($order_id)
{
    //getting order object
    $order = wc_get_order($order_id);
    $product_id_arr = [];
    //getting all line items
    foreach ($order->get_items() as $item)
    {
        $product = $item->get_product();
        $product_id_arr = $product->get_id(); //storing the product ID
        //$product_sku = $product->get_sku();
    }
    //$product_id_arr has all the order's product IDs
    //now you can do your stuff here.
}

add_action('woocommerce_thankyou', 'wh_getProductIds', 10, 1);

Code goes in functions.php file of your active child theme (or theme). Or also in any plugin php files.
Code is tested and works. version 3.x or above
