There are two ways for advert to be removed from your website, the first is for it to expire after a set duration. This duration should be calculated by the 'days to advertise' sent to you during the initial posting. You are responsible for expiring adverts, Broadbean will not send a delete request to your system in this case.
The second is for the user to decide to remove the advert before its natural expiry. To achieve this the user will use the 'delete' function in the Broadbean interface, this will send a real time delete request to your website. You should act on this request immediately and provide Broadbean with a response if it has been successfully removed.
