Overview

Subscribe and unsubscribe to Inline checkout events.

Use case

1. Add an HTML link or button in your page like the one below.

2. Create a JavaScript click handler to execute the Inline Client desired methods.

3. Use the TwoCoInlineCart.products.add({code, quantity, options}) method to prepare your catalog product.

       alert('Cart was closed.');
   });
   TwoCoInlineCart.events.unsubscribe('cart:closed', cartClosedhandlerGuid);
