Actually am getting my total amount of product in Observer of event
sales_order_invoice_save_after
Now I need to place this amount in a url and access the particular url and get back the response. How can be it done?
And also in this observer how can i get the product attribute values?
$observer->getEvent()->getInvoice()->getOrder() -> getData();
By the above code am getting the order details, but i need to get the product details.
Thanks
