              title -- your message's title, otherwise your app's name is used
              url -- a supplementary URL to show with your message
              url_title -- a title for your supplementary URL, otherwise just the
                  URL is shown
              priority -- send as --1 to always send as a quiet notification, 1
                  to display as high--priority and bypass the user's quiet hours,
                  or 2 to also require confirmation from the user
              timestamp -- a Unix timestamp of your message's date and time to
                  display to the user, rather than the time your message is
                  received by our API
              sound -- the name of one of the sounds supported by device clients
                  to override the user's default sound choice.
