Yes. In-built layer is valid as long as the instance of bot is available. Once the instance is gone, we don't have data or behavioral persistence. Since REST web API is stateless, any REST action cannot get hold of history by itself i.e. there is not session state for example.
JFYI. I managed this by creating a Singleton bot instance, where bot is supposedly active for the lifetime of web API and for all web requests, hence it persists its state.
