# Pause an A/B test

`POST /api/ab-tests/{id}/pause`

## Request

- Base URL: `https://api.setluca.com`
- URL: `https://api.setluca.com/api/ab-tests/{id}/pause`
- Auth: API key in cookie `luca.session_token`

Stops assigning new leads and keeps the results so far. Only a running test can pause. Start it again later and it picks up where it left off.

**Session-only.** This endpoint isn't on the API-key allowlist. An organization API key gets a 403 here, whatever scopes it holds.

## Path parameters

- `id` string, uuid, required

## Headers

- `Luca-API-Version` '1'

## Response `200`
