Push notifications with Knock

Knock supports sending push notifications directly to native services such as Apple Push Notifications system (for iOS notifications) and Firebase Cloud Messaging (for Android push notifications). We also support delivery of notifications through push intermediary services such as Expo.

Features

  • No stateful connections to manage: we take care of all of the complexity of managing and maintaining stateful connections to your push providers, just simply send us notifications and we'll get them delivered!
  • Cross-provider, single template: you can send the same templated message across multiple providers to reduce the amount of templates to maintain.

Channel groups

When you create your first push channel in Knock, you'll notice that we offer a channel group that combines both Apple Push Notifications system and Firebase Cloud Messaging. If you are sending notifications directly to each of these services today, consider using a channel group in Knock.

A channel group can send to multiple providers at once from a single channel step within a workflow. Here's why that's powerful.

Without a channel group in place, any workflows that send push notifications will need two channel steps in place, one for Apple and one for Firebase. This can be valuable when you want to take advantage of provider-specific functionality, but in cases where you want to send identical notifications to both providers, it means duplicating (and maintaining) the notification design across both channel steps.

With a channel group in place, you can send identical notifications to Apple and Firebase, from the same channel step. This means you can design the notification once, and move on.

Channel groups are currently enabled on an on-demand basis. If you'd like it enabled for your account, you can request access in the dashboard or send us a note using the feedback button at the top of this page.
