## API types
This section describes the data objects returned by the endpoints in the segments API. For information on a specific endpoint, refer to its specific description above.
### Segment {#segment-type-description}
#### Example
``` json
{
"id": 12054,
"name": "segment name",
"description": "segment description",
"constraints": [],
"createdBy": "you@example.com",
"createdAt": "2022-05-23T15:45:22.000Z"
}
```
#### Description
| Property | Type | Required | Description | Example value |
|---------------|------------------------------------------------------------|----------|---------------------------------------------------------------------------|----------------------------------|
| `id` | number | Yes | The segment's ID. | `546` |
| `name` | string | Yes | The segment's name | `"my-segment"` |
| `description` | string | No | An optional description of the segment. | `"segment description"` |
| `constraints` | list of [constraint objects](#constraint-type-description) | Yes | The list of constraint objects in the segment. | `[]` |
| `createdBy` | string | No | An identifier for who created the segment. | `"you@example.com"` |
| `createdAt` | timestamp string | Yes | The time when the segment was created. Format: `YYYY-MM-DDThh:mm:ss.sTZD` | `"2022-04-23T13:56:24.45+01:00"` |
### Constraint {#constraint-type-description}
#### Example
```json
{
"contextName": "appName",
"operator": "STR_CONTAINS",
"values": [],
"inverted": false,
"caseInsensitive": false
}
```
#### Description
:::note `values` and `value`
Some constraint operators only support single values. If a constraint uses one of these operators, the payload will contain a `value` property with the correct value. However, for backwards compatibility reasons, the payload will *also* contain a `values` property. If the operator accepts multiple values, the `value` property will not be present. Visit the [strategy constraints documentation](../../advanced/strategy-constraints.md) for more information on what operators support what number of values.
:::
| Property | Type | Required | Description | Example value |
|-------------------|-----------------------------------------------------------------------------------------------|----------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------|

| `operator` | string, the name of one of the [constraint operators](../../advanced/strategy-constraints.md) | Yes | The operator to apply to the context field. | `"DATE_BEFORE"` |
| `values` | a list of strings | Yes | The list of values to apply the constraint operator to. | `["value a", "value b"]` |
| `value` | string | No | The value to apply the constraint operator to. | `"15"` |
| `inverted` | boolean | No | Whether the result of [the constraint will be negated or not](../../advanced/strategy-constraints.md#constraint-negation). | `false` |
| `caseInsensitive` | boolean string | No | Whether the constraint operator is case sensitive or not. Only [applies to some string-based operators](../../advanced/strategy-constraints.md#string-operators). | `false` |
