Creates a segment with a name and, for a dynamic one, filters.

Mautic API: https://cotlet.dev/docs/api/mautic.md

`POST https://cotlet.dev/api/v1/mautic/segments`

Access: write. Confirm: waits for the user's OK before it runs.

Creates a segment as the New button on Segments does. With filters it is dynamic: each filter is a field, an operator and a value, joined with and or or. A field appears as a filter only when it has Available for Segments set to Yes in the custom field settings. Without filters the segment is static and starts empty. A new segment reaches nobody, but it can feed a campaign. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `name` | string | yes | Segment name. |
| `description` | string | no | Description shown in the segment list. |
| `filters` | array | no | Filters as objects with field, operator, value and glue (and or or). |
