Device Interests

Device Interests target groups of devices. They use the Publish/Subscribe model to decide which devices should receive a particular message.

With Device Interests, a device "subscribes" to an Interest. Then when your servers publish a push notification to a Device Interest, only the devices subscribed to that Interest will receive it.

Device interests are anonymous. They are useful when the identity of the end user is not important - you just want to publish to groups of devices.

Device Interests have no concept of who owns the device. If you want to target a specific user across all their devices, consider using Authenticated Users.

Limits

  • A device can be subscribed to a maximum of 5000 Device Interests.
  • Device Interest names are limited to 164 characters and can only contain ASCII upper/lower-case letters, numbers or one of _-=@,.;
