# Revoke a user's sessions

`POST /v1/users/{user_id}/sessions:revoke` · permission `sessions:write`

Revokes the user's sessions and the refresh token families bound to them; access tokens they issued stop being accepted by introspection and the revocation check. Without a body (or with `{}`) every session of the user is revoked. At most one filter may be given:

- `session_id`: only that session (it must belong to the user, otherwise `404`).
- `org_id`: the sessions opened in that organization's context and the user's refresh token families for that organization.
- `client_id`: only that application's refresh token families for this user; the sessions stay open. Use the application id (`app_…`); the URL-form `client_id` of a Client ID Metadata Document application is not accepted.

Sessions that are already revoked or expired are not counted, so a repeated call succeeds with zero counts. Every revocation is written to the management audit log. Send an `Idempotency-Key` header to make retries safe.

## Request

| Parameter | In | Required | Description |
|---|---|---|---|
| `user_id` | path | yes | User id, prefixed `usr_`. |

Optional body (at most one field):

| Field | Type | Required | Description |
|---|---|---|---|
| `session_id` | string | no | Session id, prefixed `ses_`. |
| `org_id` | string | no | Organization id, prefixed `org_`. |
| `client_id` | string | no | Application id, prefixed `app_`. |

## Response

`200 OK`.

```json
{
  "revoked_sessions": 2,
  "revoked_token_families": 3
}
```

`revoked_sessions` is `0` with `client_id` (sessions stay open).

## Errors

Every error is an `application/problem+json` body with a stable `code`.

| HTTP | `code` | When |
|---|---|---|
| 400 | `malformed_request`, `unknown_field` | The body is not valid JSON or has an unknown field. |
| 415 | `unsupported_media_type` | A body was sent without `Content-Type: application/json`. |
| 422 | `validation_failed` | More than one filter (`mutually_exclusive`), a malformed id (`invalid_value`), or the organization or application does not exist in this environment (`not_found` at `/org_id` or `/client_id`). |
| 404 | `not_found` | The user does not exist in this environment, or `session_id` is not one of the user's sessions. |
| 401 | `unauthenticated` | The API key is missing, invalid or revoked. |
| 403 | `insufficient_permissions` | The key lacks the `sessions:write` permission. |
| 429 | `rate_limited` | The rate limit was exceeded; honor `Retry-After`. |
| 503 | `service_unavailable` | A dependency is temporarily unavailable; retry later. |
