# Event callbacks

Event callbacks are created automatically as responses to the call to a [webhook](/core-api-reference/webhooks.md) callback URL. You can read the payload sent and check the response status code.

{% hint style="info" %}
Events callbacks are retained in our database **for one month only**.

{% hint style="info" %}
This is an **immutable API**, meaning that create, update, and delete operations are not allowed on this endpoint. You can only fetch a list of event callbacks or a single event callback object.
