+name: rudder-unity-sdk
+description: Use when working with the Rudder Unity SDK rudder.sdk in a Unity project — install, bootstrap, auth, remote config, storage, stores, inventory, leaderboards, quests, battle pass, scenarios, realtime.
+---
+
+# Rudder Unity SDK (`rudder.sdk`)
+
+UPM package `rudder.sdk` (v0.4.0): LiveOps SDK for Unity. It wraps
+`Rudder.Core.dll` (namespace `RudderSdk.Core`, the .NET SDK) with Unity
+adapters in `RudderSdk.Unity`. Public API surface:
+
+- `RudderSdk.Unity` — `Rudder` (MonoBehaviour bootstrap), `RudderConfiguration`,
+  `RudderState`, platform adapters.
+- `RudderSdk.Core` — `RudderClient` and feature services (`Auth`, `Player`,
+  `RemoteConfig`, `Storage`, `ProjectStorage`, `Stores`, `Inventory`,
+  `Leaderboards`, `Quests`, `BattlePass`, `Scenario`, `Realtime`).
+- `RudderSdk.Core.Models.*` — DTOs (`PlayerProfile`, `Wallet`, `Offer`,
+  `Store`, `StorageItem`, `RankEntry`, `Quest`, `Reward`, ...).
+
+Full integration rules live in `Packages/rudder.sdk/AGENTS.md`; copy-paste
+sample scenes live in `Packages/rudder.sdk/Samples~/`. Verify signatures
+against those, never from memory.
+
+## Install
+
+Unity 6000.0+. Add the scoped registry and both dependencies to
+`Packages/manifest.json` (`com.unity.nuget.newtonsoft-json` is required —
+the package does not bundle Newtonsoft.Json):
+
+```json
+{
+  "scopedRegistries": [
+    {
+      "name": "Rudder",
+      "url": "https://hub.rudder.build/api/packages/rudder/npm/",
+      "scopes": ["rudder"]
+    }
+  ],
+  "dependencies": {
+    "rudder.sdk": "0.4.0",
+    "com.unity.nuget.newtonsoft-json": "3.2.2"
+  }
+}
+```
+
+## Bootstrap
+
+1. Create the configuration asset: `Assets > Create > Rudder > Configuration`.
+2. Set `ProjectKey` (required). Defaults: `BaseUrl` `https://api.rudder.build`,
+   `RealtimeUrl` `wss://api.rudder.build/api/realtime/ws`, `TimeoutSeconds` 10.
+3. Add the `Rudder` component to a startup scene object and assign the asset.
+   `Rudder` is `[DefaultExecutionOrder(-1500), DisallowMultipleComponent]`,
+   uses `DontDestroyOnLoad`, and pumps `client.Update(Time.deltaTime)` every
+   frame — never call `client.Update` yourself.
+4. Initialize and sign in:
+
+```csharp
+using RudderSdk.Unity;
+
+var client = Rudder.Initialize();                                  // synchronous, idempotent
+await client.AuthorizeWithDeviceAsync("global", "en", nickname: "Player");
+```
+
+`Rudder.Initialize()` throws if the component or configuration is missing.
+`Rudder.State` (`NotInitialized`/`Initializing`/`Ready`/`Failed`),
+`Rudder.LastError`, `Rudder.Client`, `Rudder.Ready` (Task) and
+`Rudder.Initialized` (event) expose lifecycle. Details:
+[reference/bootstrap.md](reference/bootstrap.md).
+
+## Platform adapters
+
+`RudderUnityClientFactory.Create(RudderUnityClientOptions)` wires Core
+abstractions to Unity implementations; `Rudder.Initialize()` does this for
+you with `PlayerPrefsUnityKeyValueStore` + `UnityDebugLoggerSink`:
+
+| Core abstraction | Unity adapter | Notes |
+| --- | --- | --- |
+| `IRudderTransport` | `UnityTransportAdapter` over `UnityWebRequestExecutor` | `UnityWebRequest`, timeout from config |
+| `ITokenStore` | `UnityTokenStoreAdapter` | tokens in PlayerPrefs |
+| `IDeviceIdProvider` | `UnityDeviceIdProvider` | GUID in PlayerPrefs (`rudder_device_id`) — not `SystemInfo.deviceUniqueIdentifier` |
+| `IClock` | `UnityClock` | `DateTimeOffset.UtcNow` |
+| `IPlanStateStore` | `UnityPlanStateStore` | scenario runs persist in PlayerPrefs |
+| `IRudderLogger` | `UnityLoggerAdapter` → `IUnityLoggerSink` | default `UnityDebugLoggerSink` → `Debug.Log*` |
+| `IRealtimeTransportFactory` | `UnityRealtimeTransportFactory` | WebGL: `JsWebSocketAdapter` (jslib); else `NativeWebSocketAdapter` |
+
+## Capabilities
+
+All calls hang off `client` / `Rudder.Client`. Match the task to one row,
+then read the reference file for exact signatures.
+

+
+## Hard rules
+
+- Call the SDK from a `MonoBehaviour` or the game's service object; no second
+  singleton next to `Rudder`, no wrapper layers, no consumer-local interfaces
+  over `RudderClient`.
+- Use SDK model types directly; do not re-wrap `Offer`/`PlayerProfile`/
+  `RankEntry` in project DTOs unless asked.
+- No `ConfigureAwait(false)` in game code — continuations must return to the
+  Unity synchronization context.
+- Catch `RudderApiException` subclasses and surface `exception.Message`;
+  do not swallow errors. A 401 is retried once after a token refresh by the
+  client itself.
+- Backend entities must exist: store slug, leaderboard slug, remote-config
+  key, scenario event. Missing data is a 404, not an SDK bug.
+- Every feature call requires a matching dashboard entity; the API base is
+  `https://api.rudder.build`, dashboard `https://app.rudder.build/`.

+## Sign in

+```
+
+`RudderClient.AuthorizeWithDeviceAsync(string region, string language,

+
+- `Task<LoginViaDeviceResponse> LoginWithDeviceAsync(string region, string language, string nickname = null, CancellationToken = default)`
+- `Task<bool> RefreshAsync()` — explicit token refresh.
+- `void Logout()` — clears tokens locally.
+- `event Action<RudderAuthState> AuthStateChanged` — `RudderAuthState.SignedIn` / `SignedOut`. `SignedOut` also fires when a refresh fails.
+
+Login uses the SDK device id from PlayerPrefs. Do not pass
+`SystemInfo.deviceUniqueIdentifier`.
+
+## Profile and wallets
+
+```csharp
+var profile = await client.Player.GetProfileAsync();
+var nickname = profile.Player.Nickname;

+- `Player` — `Id`, `ProjectId`, `Nickname`, `Region`, `Language`,
+  `CreatedAt` (`DateTimeOffset?`).
+- `Wallet` — `Currency` (string), `Balance` (`long?`).
+
+Models are nullable since 0.4.0 — check fields before use. After any
+purchase or reward grant, reload the profile to see new wallet balances;
+there is no change callback.

+# Battle pass
+
+`client.BattlePass` (`BattlePassService`), verified against the bundled
+`Rudder.Core.dll`. There is no sample scene for this feature.
+
+Progress is tied to a scenario battle-pass node. Prefer `BattlePassSession`
+delivered by `Scenario.OnBattlePass` — it binds `scenarioId`/`nodeId`/
+`runId` for you. Direct `BattlePassService` calls need those ids manually.
+
+## BattlePassSession (preferred)
+
+```csharp
+client.Scenario.OnBattlePass += async session =>
+{
+    var progress = await session.GetProgressAsync();
+    await session.AddXpAsync("kills", 100);
+    var claim = await session.ClaimRewardAsync(level, BattlePassService.TrackFree);

+- `Task<ClaimBattlePassRewardResponse> ClaimRewardAsync(int level, string track, CancellationToken = default)`
+- `Task<PurchaseBattlePassPremiumResponse> PurchasePremiumAsync(CancellationToken = default)`
+- `LevelUp()` / `LevelUpAsync()`, `MaxLevel()` / `MaxLevelAsync()`,
+  `Complete()` / `CompleteAsync()` — resolve the scenario node.
+- `Get<T>(key, fallback)`, `Id`, `Context` like other sessions.
+
+`BattlePassLevelSession` (from `OnBattlePassLevel`) has `Claim()` /
+`ClaimAsync()` and a `Level` property.
+
+## BattlePassService (direct)
+
+- `Task<GetBattlePassProgressResponse> GetProgressAsync(string scenarioId, string nodeId, CancellationToken = default)`
+- `Task<AddBattlePassXpResponse> AddXpAsync(AddBattlePassXpRequest request, CancellationToken = default)`
+- `Task<ClaimBattlePassRewardResponse> ClaimRewardAsync(ClaimBattlePassRewardRequest request, CancellationToken = default)`
+- `Task<PurchaseBattlePassPremiumResponse> PurchasePremiumAsync(PurchaseBattlePassPremiumRequest request, CancellationToken = default)`
+- Track constants: `BattlePassService.TrackFree`, `BattlePassService.TrackPremium` (static fields).
+
+Request models carry `ScenarioId`, `NodeId`, and (except progress)
+`RunId`; `PurchaseBattlePassPremiumRequest` also takes `IdempotencyKey`.
+
+## Response models
+
+- `GetBattlePassProgressResponse` — `Level` (`int?`), `Xp` (`long?`),
+  `PremiumOwned` (`bool?`), `ClaimedTiers` (`List<ClaimedTier>`: `Level`,
+  `Track`).
+- `AddBattlePassXpResponse` — `Xp` (`long?`), `Level` (`int?`),
+  `LeveledUp` (`bool?`), `MaxLevel` (`bool?`), `Plan` (`ExecutionPlan`).
+- `ClaimBattlePassRewardResponse` — `Success` (`bool?`),
+  `AlreadyClaimed` (`bool?`), `Granted` (`List<Reward>`), `Error`.
+- `PurchaseBattlePassPremiumResponse` — `Success` (`bool?`), `Error`,
+  `Plan` (`ExecutionPlan`).
+
+Business failures come back in the response (`Success != true`, `Error`)
+with codes from `RudderErrorCodes` (`LevelNotReached`,
+`ObjectivesIncomplete`, `NodeNotActive`, `RunExpired`, ...); transport
+failures throw `RudderApiException` subclasses.

+| `TimeoutSeconds` | `int` (`[Min(1)]`) | `10` | HTTP request timeout. |
+
+Keep the asset with the real key out of git (this repo uses the git-ignored
+`Assets/LiveOpsLocal.asset` pattern).
+
+## Rudder (MonoBehaviour)
+
+`[DefaultExecutionOrder(-1500), DisallowMultipleComponent]`. Put it on a
+startup scene object, assign the configuration asset. `Awake` keeps the first
+instance (`DontDestroyOnLoad`) and destroys duplicates. `Update` pumps
+`_client.Update(Time.deltaTime)` (scenarios and realtime need it — do not
+call `client.Update` yourself). On quit/destroy it disconnects realtime.
+
+Static API:
+
+- `RudderState State` — `NotInitialized` / `Initializing` / `Ready` / `Failed`.
+- `Exception LastError` — initialization error when `State` is `Failed`.
+- `RudderClient Client` — the Core client; throws `InvalidOperationException`
+  until `State` is `Ready`.
+- `Task<RudderClient> Ready` — completes with the client after `Initialize`,
+  faults on initialization error. Prefer `Initialize()` in game code.
+- `event Action<RudderClient> Initialized` — attach point for add-on
+  packages; late subscribers must check `State` themselves.
+- `RudderClient Initialize()` — synchronous. Reads the serialized
+  configuration, creates `RudderClient` via `RudderUnityClientFactory`.
+  Idempotent: returns the same client when already `Ready`; resets and
+  retries after `Failed`. Throws if the component is not in the scene or no
+  configuration is assigned. Does not create a GameObject.
+
+Statics reset on Enter Play Mode without domain reload
+(`RuntimeInitializeOnLoadMethod(SubsystemRegistration)`).
+
+## Minimal startup
+
+```csharp
+using RudderSdk.Unity;
+using UnityEngine;
+
+public class Bootstrap : MonoBehaviour
+{
+    private async void Start()
+    {
+        var client = Rudder.Initialize();
+        await client.AuthorizeWithDeviceAsync("global", "en", nickname: "Player");
+    }
+}
+```
+
+`AuthorizeWithDeviceAsync` logs in with the SDK device id (a GUID persisted
+in PlayerPrefs under `rudder_device_id`) and restores persisted scenario
+runs. It is the first awaited call; afterwards use `client.*` /
+`Rudder.Client.*`. Tokens persist in PlayerPrefs, so a second launch can call
+it again (it refreshes the session). See
+[authentication.md](authentication.md) for the Auth service.
+
+## Errors
+
+All API errors are `RudderApiException` subclasses from `RudderSdk.Core`:
+
+- `RudderAuthException` — 401; refresh failed, session over
+  (`AuthStateChanged(SignedOut)` fires).
+- `RudderNotFoundException` — 404.
+- `RudderRateLimitException` — 429.
+- `RudderNetworkException` — no response / timeout.
+
+`RudderApiException` exposes `StatusCode` (int), `Code` (string),
+`RequestId` (string). The client retries a 401 once after a single-flight
+token refresh — game code does not implement that retry. Catch and surface
+`exception.Message`; do not swallow errors.
+
+Removed APIs (do not use): `Rudder.Initialize(configuration)`,
+`Rudder.Auth`-style static service shortcuts, `client.Scenarios`,
+`BuyAsync`, `LoginViaDeviceAsync`, `Scenario.RestoreAsync` (folded into
+`AuthorizeWithDeviceAsync`).

+
+## Flow

+Subscribe to `On*` events **before** triggering, then trigger an event name
+configured in the dashboard (examples: `player_login`,
+`demo_round_finished`). Unsubscribe on destroy.
+
+```csharp
+client.Scenario.OnNotification += session => { /* show UI, then session.Complete() */ };
+var runs = await client.Scenario.TriggerAsync("player_login");
+```
+
+API:
+
+- `Task<IReadOnlyList<PlanRun>> TriggerAsync(string eventName, CancellationToken = default)` — returns the runs it started.
+- `Task RestoreAsync(CancellationToken = default)` — restore persisted runs.
+  Already called by `client.AuthorizeWithDeviceAsync`; do not call both.
+- `void Update(float deltaTime)` — pumped by the `Rudder` component.
+- `IReadOnlyList<PlanRun> ActiveRuns { get; }` — `PlanRun` exposes `RunId`,
+  `PlanId`, `ScenarioId`, `UserId`, `ActiveNodeIds`, `Plan`.
+
+Run state persists in PlayerPrefs (`UnityPlanStateStore`), so sessions
+survive restarts.
+
+## Events and sessions
+
+All session types expose `Id`, `ScenarioNodeContext Context`, and
+`T Get<T>(string key, T defaultValue = default)` for node data.
+`ScenarioNodeContext` exposes `Run`, `Node`, `RunId`, `PlanId`, `ScenarioId`,
+`NodeId`, `Type`, `Data` (`JObject`), `AsObjectDictionary()`.
+
+| Event | Session | Game must |
+| --- | --- | --- |
+| `OnNotification` | `NotificationSession` | Show UI, then `Complete()` / `CompleteAsync()`. |
+| `OnStoreOffer` | `StoreOfferSession` | Show offer (`session.Data`, `session.Get("storeSlug", ...)`); on buy call `Stores.PurchaseAsync` then `Purchase()` / `PurchaseAsync()`, else `Decline()` / `DeclineAsync()`. `IsResolved` marks resolution. |
+| `OnConfigChanged` | `ConfigChangedSession` | Re-read `RemoteConfig.Get` — patches are already applied to the cache. |
+| `OnWait` | `WaitSession` | Deadline only (`DeadlineUtc`); the runtime completes it. |
+| `OnQuest` | `QuestSession` | Scenario quest node: `AddProgress(counterKey, amount)` / `AddProgressAsync`, `Complete()` / `CompleteAsync()`, `Fail()` / `FailAsync()`. Not `client.Quests`. |
+| `OnLeaderboard` | `LeaderboardSession` | `End()` / `EndAsync()`, `RewardClaimed()` / `RewardClaimedAsync()`. |
+| `OnBattlePass` | `BattlePassSession` | Drive the session — see [battlepass.md](battlepass.md). |
+| `OnBattlePassLevel` | `BattlePassLevelSession` | `Claim()` / `ClaimAsync()` for the level reward; `Level` prop. |
+| `OnScenarioCompleted` | `PlanRun` | Log / surface. |
+| `OnScenarioFailed` | `ScenarioFailedEvent` | `Run`, `NodeId`, `Exception`. Log / surface. |
+
+Async and sync variants are equivalent; the sync variants fire-and-forget
+the same server callback. The event name must match a scenario trigger
+configured in the dashboard — an unknown event simply starts zero runs.

+# Storage
+
+Two services, both verified against the bundled `Rudder.Core.dll` and
+`Samples~/Storage/StorageSample.cs`.
+
+## Player storage — `client.Storage` (`StorageService`)
+
+Per-player key-value items. `StorageItem` is `{ Type, Id, Data }` where
+`Data` is an opaque JSON string — serialize your save object with
+`JsonUtility` or Newtonsoft; do not invent a second save format.
+
+- `Task<GetStorageResponse> GetAsync(string type = null, int limit = 100, string cursor = null, CancellationToken = default)` — pages items; response has `Items` (`List<StorageItem>`) and `NextCursor`.
+- `IAsyncEnumerable<StorageItem> ListAllAsync(string type = null, int limit = 100, CancellationToken = default)` — follows cursors for you.
+- `Task SaveAsync(IEnumerable<StorageItem> items, CancellationToken = default)` — upserts by `Type`+`Id`.
+- `Task DeleteAsync(string type, CancellationToken = default)` — deletes all items of that type.
+
+```csharp
+await client.Storage.SaveAsync(new[]
+{
+    new StorageItem { Type = "sample_save", Id = "main", Data = json }
+});
+var response = await client.Storage.GetAsync("sample_save");
+await client.Storage.DeleteAsync("sample_save");
+```
+
+## Project storage — `client.ProjectStorage` (`ProjectStorageService`)
+
+Global key-value storage shared across players (read from the SDK; writes
+respect item permissions).
+
+- `Task<GetProjectStorageResponse> GetAsync(string type = null, int limit = 100, string cursor = null, CancellationToken = default)` — `Items` + `NextCursor`.
+- `IAsyncEnumerable<ProjectStorageItem> ListAllAsync(string type = null, int limit = 100, CancellationToken = default)`
+- `Task SaveAsync(IEnumerable<ProjectStorageUpdateItem> items, string idempotencyKey = null, CancellationToken = default)`
+
+`ProjectStorageItem`: `Type`, `Id`, `Data` (JSON string), `ReadPermission`,
+`WritePermission`, `Version` (`long?`), `Size` (`long?`), `ExpiresAt`,
+`UpdatedAt`. `ProjectStorageUpdateItem`: `{ Type, Data }`.

+# Stores and inventory
+
+Verified against the bundled `Rudder.Core.dll` and
+`Samples~/StoreInventory/StoreInventorySample.cs`.
+
+## Stores — `client.Stores` (`StoresService`)
+
+```csharp
+var stores = await client.Stores.ListAsync();
+var response = await client.Stores.PurchaseAsync(storeSlug, offerId);
+if (response != null && response.Success != true)
+    throw new InvalidOperationException(response.Error ?? "Purchase rejected");
+```
+
+- `Task<IReadOnlyList<Store>> ListAsync(CancellationToken = default)`
+- `Task<Store> GetAsync(string slug, CancellationToken = default)`
+- `Task<PurchaseOfferResponse> PurchaseAsync(string storeSlug, string offerId, string idempotencyKey = null, CancellationToken = default)` — generates an idempotency key when omitted.
+
+Models:
+
+- `Store` — `Id`, `Slug`, `Name`, `Description`, `Status`, `Environment`,
+  `ProjectId`, `ScenarioId`, `Data` (`JToken`), `Offers` (`List<Offer>`),
+  `CreatedAt`, `UpdatedAt`.
+- `Offer` — `Id`, `Name`, `Price` (`OfferPrice`), `Contents`
+  (`List<OfferContent>`), `MaxPurchases` (`int?`), `CreatedAt`, `UpdatedAt`.
+- `OfferPrice` — `Currency`, `Amount` (`long?`).
+- `OfferContent` — `ItemId`, `Amount` (`long?`).
+- `PurchaseOfferResponse` — `Success` (`bool?`), `Error`, `PurchaseId`.
+
+Check `Success != true` (nullable bool), not `!Success`. After a purchase,
+reload wallets (`Player.GetProfileAsync`) and inventory — there is no
+`onChange` callback. Purchases auto-report quest metrics
+`purchase.offer:<offerId>` / `purchase.item:<itemId>` (see
+[quests.md](quests.md)). The store slug must exist in the dashboard, else 404.
+
+## Inventory — `client.Inventory` (`InventoryService`)
+
+```csharp
+var items = await client.Inventory.GetAsync();
+```
+
+- `Task<IReadOnlyList<PlayerInventoryItem>> GetAsync(CancellationToken = default)`
+- `PlayerInventoryItem` — `Slug`, `Amount` (`long?`), `NameOverride`,
+  `PropertiesOverride` (`JToken`), `UpdatedAt`.
