Push Notifications

We use Google Firebase as the messaging channel to make it easier to integrate push across multiple mobile platforms.

You will need to register your app(s) with Firebase

In order to send messages from Intilery to your app you should:

You then supply Intilery with the JSON FCM key to enable push notifications to be sent.


A customer can have more than one device, but the device is only every linked to one customer. If a customer has more than one device, when a push campaign is scheduled it is sent to all the customer's devices.

Managing the FCM Token on the Device#

To ensure that your app audience is up-to-date you need to make sure your FCM token is refreshed regularly.

Intilery will remove stale tokens that are more than 2 months old. You should configure your app to refresh the FCM token once every 30 - 45 days.

When we attempt to send a push message, if we get an error back from firebase indicating that the token is no longer valid, the token will be removed by Intilery.

Sending the FCM Token to Intilery#

When a user first installs the app, you can ask them to accept push messages.

If the user accepts, send a Register Push event to Intilery. As the customer is not signed in at this point, there will be no userId, so use the FCM generated deviceId.

Continue to use the FCM Device ID as the userId in subsequent events.

When a user does not enable push, they are anonymous, so send events to Intilery with only an anonymousId. You can use the FCM Device ID as the anonymousId.

When a customer Signs In or Registers, send an Identify as you normally would to identify the customer, then if push is enabled send a Register Push with the userId matching your unique user identifier.

Register Push Event#

A Register Push event has these properties:

  • The deviceId from firebase to uniquely identify the device
  • The fcmToken from firebase enabling push notifications
  • A deviceType of iOS or Android or Web

If the user has signed in or registered, the userId will be your unique customer identifier. If they haven't, but have push enabled, then use the deviceId.

{   "userId": "<deviceId|userId>",   "event": "register push",   "type": "track",   "properties": {      "deviceId":"<deviceId>",      "fcmToken":"<fcmToken>",      "deviceType":"iOS|Android|Web"   },   "writeKey": "<writeKey>"}
