# Webhooks table changed

The presence of each __created*__, __destroyed*__, __changed*__ field
is determined by the specification filters and the actual change itself.

Previous and unchanged values are only a part of the payload if the
[specification](https://airtable.com/developers/web/api/model/webhooks-specification.md) contains them in the includes object.
