When using any integration in mParticle, you can filter the events or user attributes that you want via the Filters. But for Braze it's also possible to filter some other events via the connection setting.

When working with Braze, always make sure to check both the filters and your connection configuration. In case you want to know more about Braze settings, visit our docs.
