如何在 woocommerce 中为购物车创建 API？

Question

I am aware of the fact that Woocommerce provides APIs for most of its functionalities. I have gone through the below documentation

Woocommerce REST API

Now cart is one of the most important features of any e-commerce application. I did some research and found that the cart works with sessions on the web. Now I am not understanding how to create API for cart in Woocommerce. I have done a lot of research but in vain. Nothing seems to work. There must be a way to do this. Any help is appreciated.

To synchronize the cart with your backend, you would need to listen for the woocommerce_add_to_cart and send information about the cart to your backend whenever an item gets added to the cart.

Within your functions.php add the code below to add a hook to listen for the woocommerce_add_to_cart function and run the track_add_to_cart method.

add_action('woocommerce_add_to_cart', 'track_add_to_cart');
function track_add_to_cart() {
    global $woocommerce;
    $items = $woocommerce->cart->get_cart();

    foreach($items as $item => $values) { 
        $_product =  wc_get_product( $values['data']->get_id()); 
        // build a POST request and send product info to your server
    } 
}
