:::endpoint DELETE /v1/me/devices/{app}

Stops notifications for one app on the device making the request. `{app}` is
`mail`, `calendar` or `admin`. The token stays signed in; only the notifications stop.

There is no need to call this before [signing out](/docs/api/apps/sign-out):
ending the token ends its registrations too.

## Request

```bash
curl -X DELETE https://api.proppertrading.com/v1/me/devices/mail \
  -H "Authorization: Bearer ptat_9f2c1a44_3b8e7d2f5c9a1b4e6d8f0a2c4e6b8d1f"
```

## Response

`204`, no body, also when nothing was registered.
