# Unregister an install from push

POST https://api.finput.com.au/api/v1/notifications/devices/unregister
Content-Type: application/json

Call on sign-out. Removes the caller's registration for `token`. Always `204`, whether or not the token was registered, and a token registered to someone else is left untouched. A POST with the token in the body rather than a DELETE with it in the path, so the token never appears in an access log.

Reference: https://docs.finput.com.au/api/endpoints/notifications/unregister-push-device
