Creating an add to cart URL for a simple WooCommerce product Type your website's URL and add /? add-to-cart= followed by the product ID. For example, if your website's URL is https://example.com and the product ID is 123, the URL would be https://example.com/?add-to-cart=123 .

To create the link, you need to append “add-to-cart=ID” to your domain address. All you'll need to do is replace the ID with the product ID you want to add to the cart upon clicking on the link we will create. Note: if you don't specify the product quantity, a single product will be added to the cart.

The WooCommerce Cart URL can be fetched with a call to the cart object's get_cart_url() method. To fetch the cart URL we need global $woocommerce variable. If it is not declared then we would be not able to fetch it.
