Sending a notification to a user

To send a notification there are three steps:

  1. Create a topic

  2. Create a subscription that listens to the topic

  3. Send a message to the topic


The message sent to the topic and read by the subscriber is a JSON formatted document. In this context, the JSON must contain at least two things:

  • the actual content of the notification to send

  • the device id / email address to send the notification to


Example for email:

{
"email_to" : "foo@bar.com",
"subscriber_content" : "Hi, this is your FME Server"
}

Notification content

This is the message you want to broadcast out to anyone that is subscribed.


“subscriber_content”: “here is the notification message”

Device ids / email addresses

For each subscription protocol the JSON is slightly different. Notifications can be sent to one device/user or multiple. For multiple you just need to separate the identifiers with a comma.

Subscribers

Example JSON

"gcm_token" : "987654,83667"
