      description: '**EXPERIMENTAL ENDPOINT** - Subject to change without notice.


        Updates a single feature state within an environment. You can update either:

        - The environment default state (when no segment is specified)

        - A specific segment override (when segment.id is provided)


        **Feature Identification:**

        - Use `feature.name` OR `feature.id` (mutually exclusive)


        **Value Format:**

        - The `value` field is always a string representation

        - The `type` field tells the server how to parse it

        - Available types: integer, string, boolean

        - Examples:

        - `{"type": "integer", "value": "42"}`

        - `{"type": "boolean", "value": "true"}`

        - `{"type": "string", "value": "hello"}`


        **Segment Priority:**

        - Optional `segment.priority` field controls ordering

        - If field value is null or the field is omitted, lowest priority is assumed'

      description: '**EXPERIMENTAL ENDPOINT** - Subject to change without notice.


        Updates multiple feature states in a single request. This endpoint allows

        you to configure an entire feature (environment default + all segment overrides)

        in one operation.


        **What You Can Update:**

        - Environment default state (required)

        - Multiple segment overrides (optional)

        - Priority ordering for each segment


        **Feature Identification:**

        - Use `feature.name` OR `feature.id` (mutually exclusive)


        **Value Format:**

        - The `value` field is always a string representation

        - The `type` field tells the server how to parse it

        - Available types: integer, string, boolean

        - Examples:

        - `{"type": "string", "value": "production"}`

        - `{"type": "integer", "value": "100"}`

        - `{"type": "boolean", "value": "false"}`


        **Segment Overrides:**

        - Provide array of segment override configurations

        - Each override must specify: segment_id, enabled, value

        - Optional priority field controls ordering

        - Duplicate segment_id values are not allowed'
