Webhooks

Overview

Webhooks are primarily used to have a trusted source of game configurations and room compositions and can greatly contribute to the safety of an online application.

The default cloud plugin has support for different hooks defined via the AppID Dashboard. Once configured and enabled, the Photon Cloud will send WebRequests (HTTP POST) to a custom backend and will use the response data (Json) for various configurations on the Photon rooms and game sessions.

Setup

Webhooks are enabled per AppId on the Photon Dashboard.

1. Navigate to the Photon Dashboard and log in.
2. Find the AppId and click Manage.
3. Scroll down to Plugins and click Edit.
4. Click Add New Pair and add keys and values (the maximum length allowed for each setting value is 1024 chars).
5. Press Save and wait up to one minute for changes to take effect.

Dashboard Configurations

WebHookBaseUrl	string	https://localhost:3581	The base url of the custom backend. Webhook paths will be appended, for example: {WebHookBaseUrl}/game/create Must always be set.
WebHookIntegration	string	Default	The selected webhook integration (default is Default). Default, PlayFab
WebHookSecret	string	**********	This will be send with each web request and can be used to authenticate the request.
WebHookCustomHttpHeaders	Dictionary <string, string>	{"A": "Foo", "B": "100" }	A JSON dictionary. All entries will be added to the custom web request headers.
WebHookEnableOnCreate	bool	true	If set to true, the CreateGame webhook will be fired when a client is creating a Game Session.
WebHookEnableOnClose	bool	false	If set to true, the CloseGame webhook will be fired when the Game Session was closed.
WebHookEnableOnJoin	bool	true	If set to true, the JoinGame webhook will be fired when any client tries to join a Game Session.
WebHookEnableOnLeave	bool	false	If set to true, the LeaveGame webhook will be fired when any client leaves a Game Session

Quantum Dashboard Configurations

Key	Type	Example	Description
WebHookEnableGameConfigs	bool	false	If set to true, the GameConfigs webhook will be fired when a client uploaded the game configs RuntimeConfig and SessionConfig using the StartRequest operation.
WebHookEnableGameResult	bool	false	If set to true, the GameResult webhook will be invoked.
WebHookEnableAddPlayer	bool	false	If set to true, the client operation AddPlayer will invoke the AddPlayer web request.
WebHookEnablePlayerAdded	bool	false	If set to true, the PlayerAdded web request is invoked after a player has been successfully added to the Quantum online game.
WebHookEnablePlayerRemoved	bool	false	If set to true, the PlayerRemoved web request is invoked after a player was removed from the Quantum game.
WebHookEnableReplay	bool	false	Setting this to true will enable the replay streaming based on the ReplayStart and ReplayChunk web requests.

Webhook API

Webhooks send Json content and only accept Json content as a response. UTF-8 charset for Json is mandatory.

Webhooks expect HTTP response codes 200 or 400:

• 200: successful request.
• 400: error or operation has been denied (e.g. a client cannot create a room/game session).

The Photon server retries webhooks after transportation errors three times as well as after receiving StatusCode 503 (Service Unavailable) with delay of 400ms, 1600ms and 6400ms. The timeout before the request fails and is not retried is 10 seconds.

Fill out the WebhookError definition to return information of the nature of an error back to the Photon plugin. It can be used for:

• Logging;
• Returning information to the client;
• A custom plugin to add further custom error handling;

Common Request Headers

These common request headers are added to every web request.

Name	Type	Content	Description
Accept	string	application/json	Webhooks only accept JSON as a response body
Accept-Charset	string	utf-8	Webhooks only accept utf-8 as response body charset
Content-Type	string	application/json	Webhooks all send JSON body data
X-SecretKey	string	**********	This key should only be know to the custom backend and should be used to authenticate the incoming web request. This is set on the Photon Dashboard as WebHookSecret.
X-Origin	string	Photon	Will always be set to "Photon"

CreateGame

This webhook is called before the room/game session is created on the Photon Server. The creation is blocked until the webhook receives a response, which will affect the time clients require to create a connection.

A CreateGame webhook is always a JoinGame request for the user that initiates the room/game session creation. There will be no subsequent JoinGame webhook for this user. This webhook shares the data from the JoinGame webhook.

Requires WebHookBaseUrl and WebHookEnableCreateGame to be set on the Photon dashboard.

Quantum Classes

RuntimeConfig

Quantum 3 runtime configuration files RuntimeConfig and RuntimePlayer are uploaded by the clients using Json serialization. This way it is possible to send configurations to the Quantum public cloud game servers while it does not know the implementation and serialization details.

When RuntimeConfig or RuntimePlayer are used in a webhook response they need to be complete because the configs send by clients are completely replaced.

Json data sent by the custom backend has to be deterministically deserializable on every client.

Quantum internal classes usually operate with fields, make sure that the Json serialization and deserialization code needs to IncludeFields = true and IgnoreReadOnlyProperties = true.

A simple example of the RuntimeConfig class. Additionally to the partial declaration the base class adds a couple properties as well (Seed, Map, SimulationConfig, SystemsConfig).

The $type property is required for deserialization on the standalone or custom plugin.

C#

namespace Quantum {
  public partial class RuntimeConfig {
    public int GameMode;
  }
}

Json Example:

JSON

{
  "$type": "Quantum.RuntimeConfig, Quantum.Simulation",
  "GameMode": 1,
  "Seed": 0,

RuntimePlayer

C#

namespace Quantum {
  public partial class RuntimePlayer {
    public AssetRef<GearConfig> Loadout;
  }
}

Json Example:

JSON

{
  "$type":"Quantum.RuntimePlayer, Quantum.Simulation",
  "Loadout": {
    "Id": {
      "Value": 440543562436170603
    }
  },
  "PlayerAvatar": {
    "Id": {
      "Value": 2430278665492933905
    }
  },
  "PlayerNickname": "foo"
}

SessionConfig

SessionConfig is the abbreviation of the DeterministicSessionConfig class.

When a SessionConfig is returned by an webhook it needs to be complete because single values are not replaced.

The current SessionConfig asset can be exported in Unity using this menu entry:

Unknown

Unity Editor > Quantum > Export > SessionConfig (Json)

When serializing the class on netcoreapp3.1 either use Newtonsoft or use DeterministicSessionConfigJsonConverter for Text.Json. Because "including fields" is a feature of net5.

Json Example:

JSON

{
  "PlayerCount": 8,
  "ChecksumCrossPlatformDeterminism": false,
  "LockstepSimulation": false,
  "InputDeltaCompression": true,
  "UpdateFPS": 60,
  "ChecksumInterval": 60,
  "RollbackWindow": 60,
  "InputHardTolerance": 8,
  "InputRedundancy": 3,
  "InputRepeatMaxDistance": 10,
  "SessionStartTimeout": 1,
  "TimeCorrectionRate": 4,
  "MinTimeCorrectionFrames": 1,
  "MinOffsetCorrectionDiff": 1,
  "TimeScaleMin": 100,
  "TimeScalePingMin": 100,
  "TimeScalePingMax": 300,
  "InputDelayMin": 0,
  "InputDelayMax": 60,
  "InputDelayPingStart": 100,
  "InputFixedSizeEnabled": true,
  "InputFixedSize": 24
}

GameResult Event

The GameResult class can be extended by adding fields using the partial class declaration inside the GameResult.User.cs script. It will be Json serialized on the client and send to the Quantum server.

C#

namespace Quantum {
  public partial class GameResult {
    public int Winner;
  }
}

Json Example:

JSON

{
  "$type":"Quantum.GameResult, Quantum.Simulation",
  "Frame": 200,
  "Winner": 2
}

The game result event can be invoked once per game by each client, which is triggered from inside the simulation by calling the GameResult Quantum event. The actual webhook is launched when the room is disbanded and closed.

C#

f.Events.GameResult(new GameResult { WinnerId = 3 });

When running an enterprise Photon Quantum cloud with server simulation this will be transparently send by the server for a trusted source of game results.

Photon Realtime Classes

EnterRoomParams

This definitions is designed to be similar to the EnterRoomParams class in Photon Realtime. It includes all options that can be set by the CreateGame webhook. When composing the Json Response every member is optional and can be null or not set.

Name	Type	Description
RoomOptions	RoomOptions	RoomOptions object
ExpectedUsers	string[]	A list of UserIds that are permitted to enter the room/session (additionally to the user creating the room). If MaxPlayers is greater than the number ExpectedUsers listed, any player may join and fill the unreserved slots. Works only for RoomJoin() not JoinRandom().

Json example:

JSON

{
  "RoomOptions": {
    "IsVisible": true,
    "IsOpen": true,
    "MaxPlayers": 8,
    "PlayerTtl": null,
    "EmptyRoomTtl": 10000,
    "CustomRoomProperties": {
      "Foo": "bar",
      "PlayerClass": 1
    },
    "CustomRoomPropertiesForLobby": [
      "Foo"
    ],
    "SuppressRoomEvents": null,
    "SuppressPlayerInfo": null,
    "PublishUserId": null,
    "DeleteNullProperties": null,
    "BroadcastPropsChangeToAll": null,
    "CleanupCacheOnLeave": null,
    "CheckUserOnJoin": null
  },
  "ExpectedUsers": [
    "A",
    "B",
    "C"
  ]
}

RoomOptions

All values are nullable types and can be set to null or be omitted when sending back to the Quantum server, in which case this response will not alter the nulled or omitted room property and will remain the default or the value send by the client when creating the room.

Name	Type	Description
IsVisible	bool	Defines if this room is listed in the Photon matchmaking.
IsOpen	bool	Defines if this room can be joined by other clients.
MaxPlayers	byte	Max number of players that can be in the room at any time. 0 means "no limit".
PlayerTtl	int	Time To Live (TTL) for an 'actor' in a room. If a client disconnects, this actor is inactive first and removed after this timeout. In milliseconds.
EmptyRoomTtl	int	Time To Live (TTL) for a room when the last player leaves. Keeps room in memory for case a player re-joins soon. In milliseconds.
CustomRoomProperties	Dictionary <string, object>	The room's custom properties to set during creation.
CustomRoomPropertiesForLobby	string[]	Defines which of the custom room properties get listed in the lobby. Value type of the properties has to be bool, byte, short, int, longor string. Max number of properties is 3. The max length for string value is 64. Key restrictions can also be enforced by the Photon dashboard property: AllowedLobbyProperties.
SuppressRoomEvents	bool	Tells the server to skip room events for joining and leaving players. Default is false.
SuppressPlayerInfo	bool	Disables events join and leave from the server as well as property broadcasts in a room (to minimize traffic). Default is false.
PublishUserId	bool	Defines if the UserIds of players get "published" in the room. Useful for FindFriends, if players want to play another game together. Default is false.
DeleteNullProperties	bool	Optionally, properties get deleted, when null gets assigned as value. Default is false.

PlayFab

To enable the PlayFab integration add the WebHookIntegration dashboard variable and set it to PlayFab.

• All slashes from all paths will be substituted with an underscore: game/create => game_create
• All webhook requests will automatically add the AppId property (if missing) controlled by WebHooksConfig.AppId
• All webhook requests will automatically add the UserId property (if missing) "0"
• Webhook responses will handle the following Json result body and cause the webhooks to fail on ResultCode != 0. The Message is copied on errors to WebHookError.Message.

JSON

{
    "ResultCode": 0,
    "Message": "success"
}

Photon Cloud Web Request Limitations

There are global limitations on the Photon Server per room/session. If they are hit web requests and reponse can be dropped.

• HttpRequestTimeout: 30000
• LimitHttpResponseMaxSize: 200000
• MaxQueuedRequests: 5000
