## API for communicating through MPNS

I developed an API for communicating through MPNS with Windows Phone mobile devices ([1](https://github.com/MarcosPividori/GSoC-Communicating-with-mobile-devices/tree/master/push-notify/Network/PushNotify/Mpns)). For this, I designed a way of building the messages, sending them and handling the result.

To communicate with MPNS servers, I need to send POST requests, so I decided to use Conduit, as I have done with GCM. The MPNS Api looks like this:

MPNS let you send notification in an authenticated or unauthenticated mode, so you can configure this with  MPNSConfig:

    data MPNSConfig = MPNSConfig{
            numRet       :: Int   
        ,   useSecure    :: Bool     
        ,   certificate  :: X509  
        ,   privateKey   :: PrivateKey
        }

To build messages, I developed a data type "MPNSmessage"

    data MPNSmessage = MPNSmessage{
            deviceURIs          :: HashSet DeviceURI  -- destinations
        ,   batching_interval   :: MPNSInterval       -- Immediate | Sec450 | Sec900
        ,   target              :: MPNSType           -- Toast     | Raw    | Tile
        ,   restXML             :: Document           -- the XML data to be sent
        }

For sending notifications:

    sendMPNS :: Manager -> MPNSConfig -> MPNSmessage -> IO MPNSresult

Last, for handling the result:

    data MPNSresult = MPNSresult{
            successfullResults  :: HashMap DeviceURI MPNSinfo
        ,   errorException      :: HashMap DeviceURI SomeException
        }
