Delete an Entity
You can delete a new entity using the DELETE method on the entities endpoint. You need a token with write privileges, otherwise a 401 or 403 will be sent back.
Selecting an entity to delete is done with the same parameters as the GET endpoint.
In order to avoid massive deletions by mistake, you can only delete one entity at a time.
