Hooks for updating post meta

Hi,

what are your hooks for updating post meta, i need it to replicate this function for wcfm when adding/updating product/s. I couldn’t find them.

-this is for single product update and there is one for quick save.

add_action('woocommerce_process_product_meta', 'woo_calc_my_discount', 99);
function woo_calc_my_discount( $product_id ) {
$_product = wc_get_product( $product_id );
$regular = (float) $_product->get_regular_price();
$sale = (float) $_product->get_sale_price();
	
if (!empty($sale)) {
$discount = round( 100 - ( $sale / $regular * 100), 2 );
update_post_meta( $product_id, '_discount_amount', $discount );
}
}

We use this to pull products by percentage of discount.

Thank you
