Hi Fabian, from what I understand:

1- If a player signs in with a device ID from a a phone without a playerpref file (Meaning first time or playerpref was deleted) You want to check if the device ID is connected to social account or if it even exists.

I think this will interest you - https://docs.gamesparks.com/api-documentation/request-api/player/socialdisconnectrequest.html

Also this tutorial will teach you how to place logic in an Authentication Request and process information and potentially cancel it before it goes through - https://docs.gamesparks.com/tutorials/social-authentication-and-player-profile/automating-user-password-change.html

Keep me updated and we can work on the best solution for you.

Hope this helps,

Omar

Hi Fabian, 

I think this approach might help you:

1- When player makes a Device Auth request the game check for the playerPref file.

2- If the playerPref file exists then you send a boolean set to 'True' in the Device Auth scripData, if the playerPref file does not exist then you send a 'Flase' value.

3- When the boolean(Let's name it condition) is received by Cloud Code and it's false(No playerPref associated with player) then we run some logic to remove connected social accounts.

This is the way I've done it:

The Device Auth request sent from the Test Harness:

{

 "@class": ".DeviceAuthenticationRequest",

 "deviceId": "testGS",

 "deviceOS": "UE4",

 "scriptData": {

  "condition": false

 }

}

When that scriptData makes it into the request as false, we'll forward it to the response:

//Get condition

var condition = Spark.getData().scriptData.condition;

//If condition is false meaning no playerPref, we're going to remove social accounts linked

if(condition == false){

Spark.setScriptData("condition", condition);

}

When that data makes it to the response we want to check if that player exists, if it exists then we want to unlink social profiles linked to it, for example FB:

//Get the Data associated with this request, including scriptData forwarded from request

var dataExample = Spark.getData();

//Check if condition exists

if(dataExample.condition !== null){

    //If so then diconnect social profiles

   if(!Spark.getData().newPlayer){

      var socialRequest = new SparkRequests.SocialDisconnectRequest();

      //FB is one example, please check API doc for more options

      socialRequest.systemId = "FB";

      //Finally send this request on behalf of player

      socialRequest.SendAs(Spark.getPlayer().getPlayerId()); 

   }

}

Hope this basic example sheds some light on the process. If you need anymore help please let us know.

Cheers,

Omar

Device authentication isn't something you can link or delink unfortunately because it's saved in the userName:

GameID-Platform-DeviceUniqueID

for example:

293711-W8-exampleUniqueDeviceID

If you want to access it in the database using Device Authentication request Cloud Code, this is the way to do it

//GameID + deviceOS + deviceID

var deviceUserName = "293711-" + Spark.getData().deviceOS + "-" + Spark.getData().deviceId;

//Load player collection

var players = Spark.systemCollection("player");

//Find user with that username

var playerId = players.findOne({"userName" : deviceUserName}, {_id : 1});

//Load player

var player = Spark.loadPlayer(playerId._id.$oid);

However, again, you can't delink it, because it's part of the user now. You can only manually delete all the data attached  to that player or delete the player.

Hope this makes things clearer,

Omar

Hey Fabian, 

Glad that helped,

you can also change the userName using the changeDetailsRequest.

Hope this helps,

Omar
