# The segment model ## Example Segment Object ```json {\n \"type\": \"segment\",\n \"id\": \"53203e244cba153d39000062\",\n \"name\": \"New\",\n \"created_at\": 1394621988,\n \"updated_at\": 1394622004\n} ``` A segment is a group of your contacts defined by rules that you set. Contacts are automatically added to the segment every time the contact updates to match those rules. You can use [Search for contacts](#search-for-contacts) to find contacts that match the same rules. ### Segment Object | Key | Type | Description | | --- | --- | --- | | type | string | *value is segment'*. | | id | string | The unique identifier representing the segment. | | name | string | The name of the segment. | | created_at | timestamp | The time the segment was created. | | updated_at | timestamp | The time the segment was updated. | | person_type | string | Type of the record: user or lead. | | count | integer | The number of items in the user segment.
