1. Is the device ID of the Android terminal that transmits Push registered beforehand in the database or file and the content set to payload message at the time of transmission?
2. Is this database or file prepared on the application side so that it is OK? Or do you need to use the database or file specified by MAG?
1. Since MAG does not provide the mechanism of FCM Registration Token (registration token) management, it is necessary to separately create a mechanism to store the registration token.
2. There is no particular need to use the database or file specified by MAG.
Implementation is free because registration mechanism of registration token and storage mechanism are not prepared by MAG.
