I need push notification on mobile webapp (Xojo, iOS+Android), I was thinking to use Twilio Notify Beta but it is not clear to me how it works.
Say a user starts the webapp: first time it should bind with a REST api, but I don't understand where to find the "device token", how to define if the mobile user has to accept the notification or he/she has already did it, etc.
Docs are here.
Can you push me in the right direction?
