title: Trigger action when order is placed (woocommerce)
body: <p>I want to update product price <a href="https://rudrastyh.com/woocommerce/rest-api-create-update-remove-products.html#update_product_price" rel="nofollow noreferrer">as shown on this example</a>, and even when this works fine for me <strong>I need this to happen when any new order gets completed</strong>. </p>
  
  <p>How can I trigger this to every order made? Is there any kind of event in Woocommerce for a new completed order, or similar?</p>
  
  <p>Thank you.</p>
