# Update a subscriber (status, contact fields, pause/resubscribe)

`PATCH /v1/subscriber-lists/{id}/{email}`

## Request

- Base URL: `https://api.bluefox.email`
- URL: `https://api.bluefox.email/v1/subscriber-lists/{id}/{email}`
- Auth: HTTP bearer

Legacy flat URL shape. Setting status to "paused" requires pausedUntil (a future date). Accepts an API key or a whitelisted Origin header.

Double opt-in: when it is on for the list and the request uses an API key, setting status to "active" on an unverified or unsubscribed subscriber does not activate them - they keep their status, get the verification email, and the response includes verificationEmailSent: true. They become active only by clicking its link. A paused subscriber is reactivated directly. With a SubscriptionToken the change applies directly.

## Path parameters

- `id` string, required
- `email` string, required

## Request body

- object
  - `email` string
  - `status` 'active' | 'paused' | 'unsubscribed'
  - `pausedUntil` string, date-time

## Response `200`

OK

## Other responses

- `400`: Invalid request body or query - every violation found (missing/invalid/unexpected fields) is reported in one response, semicolon-separated, not just the first one hit.
- `403`: Missing or invalid API key
- `404`: Subscriber not found
- `405`: The operation is blocked by a business rule (e.g. the resource is still in use)
