Delete messages

Delete() either permanently removes a historical message from Message Persistence (DeleteMessageHard()) or marks it as deleted if you use the soft delete option (DeleteMessage()).

Usage in Blueprints and C++

Requires Message Persistence configuration

To manage messages, you must enable Message Persistence for your app's keyset in the Admin Portal. To delete messages from PubNub storage, you must also mark the Enable Delete-From-History option.
