Every application which will use the Push Notification, clients’ have to get the notification_id from the mobile application and that app needs to be sent back to us. When a person comes to the particular mobile application, we have installed a Firebase_id in it, using that code we get one token against that device and application.
We store that token inside the FirstHive Database (FHDB), when any communication needs to be sent, we use that token. This is purely token based, no mobile number, email_id or any such mode of communication used.
The clients manage their own Firebase account or we use our Firebase account while ending any communication. For using their own Firebase account, they needed to generate the token ad share with us. They also have to share the server key as well.
