# One Click Unsubscribe

`POST /v1/unsubscribe`

## Request

- Base URL: `https://api.quantradin.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.quantradin.com/v1/unsubscribe`
- Auth: none declared

RFC 8058 one-click. Idempotent: unsubscribing twice is still 'off'.

A browser form (the button on the campaign page) asks for text/html and
gets the plain confirmation; a mail client's one-click POST gets the JSON
it always got.

## Query parameters

- `token` string, required

## Response `200`

Successful Response

- unknown

## Other responses

- `422`: Validation Error
