# Batch Create Contact Lists

`POST /v1/contact-lists`

Create contact lists in batch (up to 100 items per request).

Unlike single-resource `POST` endpoints, the body wraps the payloads in
`items` and the response reports a per-item status.

Requires the `contact_lists:write` scope on the API key.

## Request body

- CreateContactListsInput
  - `items` ContactListInput[], required — Contact lists to create.
    - `name` string, required — Name of the list.
    - `default_sequence_template_id` string, uuid, nullable — Sequence template that new entries are auto-enrolled into.

## Response `200`
