Thanks for this very useful example. Just one note: if you want to push on WatchOS you have to specify in the headers also the 'apns-push-type' that must reflect what you put in the payload, for example 'apns-push-type': 'alert', as explained on the Apple site.
This is due to the fact that on the Watch you may want to use also a push to update a complication on the main screen instead of the watch app, so the operating system needs to know the destination of the notification.
