Publish option to group notification

I would like to know options to group the notification messages on the smartphone. For iOS 12, there is option to group the notification messages by providing a thread-id and summary-arg in payload. Please see more about it from

Based on the documentation, the option to add header key “thread-id” and “summary-arg” are not available in client sdk.

Client SDK (REST / Android / Objective-C / Swift / JS )

iOS Objective C version 4.5.0
Android Java version 5.2.4

Application ID


Expected Behavior

Please describe the expected behavior of the issue, starting from the first action.

  1. The PublishOptions class from Client sdk should provide option to add header key “thread-id” and “summary-arg”
  2. On iOS device, when remote push notification received, the messages should be grouped.

Hello Jay,

Custom groups are really cool and we’ll add them to our roadmap. The internal ticket BKNDLSS-18579 created.



Groups support added to iOS-SDK, ticket BKNDLSS-18579 marked as resolved. This feature will appear in the Push Templates tab on the console in the nearest future.
