Hi!

I fixed my issue by adding a WordPress filter using the “woocommerce_structured_data_product” filter option. This allows you to add new data to the already generated WooCommerce data.

Add to function.php your child theme

/*
 * Missing data WooCommerce
 */
function custom_woocommerce_structured_data_product ($data) {
	global $product;
	
	$data['gtin13'] = $product->get_meta( '_wpm_gtin_code' );
	
	return $data;
}
add_filter( 'woocommerce_structured_data_product', 'custom_woocommerce_structured_data_product' );

Thanks.
Now it works fine.

This really should be a main focus of the plugin. I’m annoyed it’s not a core feature.

I mean so many people are not going to pay 79$ a year for the official WooCom plugin, just to add GTIN to WooCommerce product schema output.

What a joke.

Add GTIN schema output to the plugin as a feature!!

It will garner so many users!

Hello!
Inside the version 1.0.6 you can find this feature.
On setting page you can choose the property name to add to the structured data.
These are the options:

• gtin
• gtin8
• gtin12
• gtin13
• gtin14
• isbn
• mpn
