# Events

Uiza  creates **`event`** objects containing data of the events occurred in your Uiza account that your applications might be interested in, for instance, a `live_entity` is created, a `ingest.key` is reset or a `video_entity` is deleted, etc. 

While some API requests do not cause any `event` to be created such as *Retrieve a live entity*, other APIs may generate more than one `event`. For example, when you create a live entity, a `live_entity.created`, a `live_entity.resource.accepted` and a `live_entity.ready` events will be created consecutively.

Fundamentally, an `event` is created whenever there is a change in the state of an API resource. Therefore, there are `events` created without the trigger of any API request. A `live_entity.publish` created when Uiza receives your live feed signal is triggered by your broadcasting software, not as the result of an API request.
