Whenever Shopify sends your App a shop, the shop parameter is filled in. So you never have to wonder who is knocking at your door. You always know, with the exception perhaps of when you offer clickable service inside your own App. At that point, you might want to include the shop as a parameter too, for cases when your session times out. You can re-auth that way.
