Extra actions after order saved

Question

I am new to Magento, but what I need to do is:

after the order is saved, I have to call an external webservice and pass some order data to this service.

Where or what is the best place to do so?

thanks in advance

Answer 1

Create custom module and call your method in sales_order_place_after event For example Your module xml

<events>
    <sales_order_place_after>
        <observers>
            <your_module_event_handler_name>
                <class>your_module/observer</class>
                <method>extraAction</method>
            </your_module_event_handler_name>
        </observers>
    </sales_order_place_after> 
</events> 

Your function

public function extraAction(Varien_Event_Observer $observer) {
    $order = $observer->getEvent()->getOrder();
    // your code here
}
