title: Magento 2, call external web service when order is placed
body: <p>I've been digging around and I can't seem to find the answer to what I'm looking for at all.</p>
  
  <p>I need to call an external web service when an order is placed in magento 2. I also need to use the order information in the call. I simply dont know what the right path is. Has anyone done this before? </p>
