Notification channels centralize all notifications sent to target users. Sendbird Business Messaging delivers an omni-channel experience, offering multiple channels such as push notifications, in-app notifications, and KakaoTalk.

On Sendbird Dashboard, you can create new notification channels for your choice of channel type that best suits the user experience of your service.

An in-app notification is a message displayed to users directly within an application.

Push notification

A push notification is a message that pops up on a mobile device from an app when it is not actively in use. Each Sendbird application is automatically provided with a single Push notification channel by default.

KakaoTalk is a market-leading messenger app in South Korea. Alim Talk is a notification service provided by KakaoTalk, and allows businesses to send official messages directly to their customers' KakaoTalk accounts.

Category filter

Copy link

Category filters are a per-channel list of categories that a user may utilize to filter the list of notifications rendered. Categories are an optional feature.

To configure category filters for a specific channel, navigate to the Sendbird Dashboard > Application > Business Messaging > Channels and select the channel which you wish to enable Category filter.

Once enabled, you can add as many or as few categories to fit your use case. Categories will always have an ID associated with them which is a static value regardless of the name of the category. This means that even though you may change the name of a category, the ID will remain the same.

Once categories have been enabled, and created, you can then associate them to your templates.

Note: Categories cannot be retroactively applied to notifications. They will only be applied to notifications that are sent after they’ve been configured. Categories can be changed on templates however previously sent notifications will still appear with the previous category.
