$product->save() trigger listing update?

Hey @howy

I first want to apologize for the late response here. Our development team has been busy and we have had a few unforeseen issues come up that caused some delays as well.

To answer your question no, not by itself. If the price or stock was changed, then WP-Lister for Amazon would pick that up and mark the listing as changed. To be sure, just add this line after the WC_Product::save() method in your code:

do_action( 'wpla_product_has_changed', $wc_product_id );

Kind regards,
John
