Using Parse Cloud Code in Conjunction with .NET SDK

Parse has a nice Documentation: Parse CloudCode

This is an example Code, which sends a push every time a user is created

//instead of Parse.User you can use any custom parse class too, but write them inside quotes
Parse.Cloud.afterSave(Parse.User, function(request) {
    if(!request.object.existed()){//existed() returns false if the object was just created
        var query = new Parse.Query(Parse.Installation);
        query.equalTo("User", request.object);
        Parse.Push.send({
            where: query,
            data: {
                badge: "Increment",
                alert: "Welcome " + request.object.get("username"),
                sound: "beep.caf"
            }
        }, {
            success: function(){
                //succeed
            },
            error: function(err){
                console.error("Got an error " + error.code + " : " + error.message);
            }
        });
    }
});

There are also other hooks available:

• beforeSave
• afterSave
• beforeDelete
• afterDelete

Inside these hooks you can send push notifications, create new objects, manipulate objects, do nearly whatever you want.

In Parse CloudCode you can take advantage of the Parse JavaScript API.
