# Unsubscribe sessions

`POST https://api.gleap.io/v3/sessions/unsubscribe`

Unsubscribe contacts by email and/or userId. Fire-and-forget: the response is always `{ "success": true }` and does not reflect whether the contacts were found or updated. Every session in the project matching an entry's email OR userId is unsubscribed; entries with neither field are ignored.

## Authorization

- `Authorization` (header, required): `Bearer <token>`

## Headers

- `project` (string, required)

## Request body (`application/json`, required)

- `reason` (string): Stored as Session.unsubscribeReason. Defaults to "CSV upload" when omitted.
- `sessions` (object[], required)
  - `userId` (string)
  - `email` (string)
