Call adding product to wishlist manually from AJAX request

Hi,

I'm looking for a wishlist plugin that will allow me to add a product outside of WordPress.

I have a js application which is not integrated in WordPress environment. Through it, I want to send an AJAX request to your plugin to add a product to your wishlist.
Can I call from my js file your plugin's action manually (in particular, adding a product to the wishlist) with the specified product id using an ajax request to functions.php?
If yes, what action should I call in functions.php?

Looking to your answer,

Thanks, Margarita
