- Broadcasting the same message to all users. It's a simple method which can be used in informational apps that do not authenticate users and where same push notification messages are broadcasted to everybody. This way when you want to send a push message you may 1) simply go to Admin panel -> Push Notifications -> type your message in Simple mode -> and hit "Send" for all of your users to receive the message; 2) Send a push using Push Notifications API (explained below). Following this way you only need to create ONE QuickBlox User which will have all of your users' devices associated with it. Then simply send your pushes to that User.
