# List segments

| --- | --- | --- | --- |
| `domain` | string | Yes | The sending domain whose segments to list. |
| `limit` | number | No | Number of segments to retrieve. Optional; if omitted, all segments are returned in a single response. Minimum `1`, maximum `100`. |
| `after` | string | No | The segment ID *after* which to retrieve more segments (for pagination). The ID is not included in the result. Cannot be combined with `before`. |
| `before` | string | No | The segment ID *before* which to retrieve more segments (for pagination). The ID is not included in the result. Cannot be combined with `after`. |
