# Create segment

Create a segment with an optional set of tags (OR logic).

Source: https://statusdashboard.com/docs/api/subscriptions/segments/create

`POST /app/segments`

Creates a segment. Requires the **Segments** plan feature and admin role.

When `tagIds` is non-empty, tags are combined with OR logic: a contact in any listed tag is considered part of the segment. An empty `tagIds` array is allowed — the segment matches no contacts until tags are added.
