# SDK

#### `Tebex.TebexUnity`

**Ready-to-use Unity MonoBehaviour components and a static store cache.**

The highest-level namespace for most Unity developers. 

Contains `StoreBrowser` (full store UI), `InGameCart` (slide-out shopping cart), `Deliverables` (post-purchase callback system), `Tebex` (static cache for store data and textures).

All components are designed to be dropped onto a GameObject and configured in the Inspector.

***

#### `Tebex.Common`

**Shared utilities and base types used across all other namespaces.**

Contains callback delegate definitions (`ApiSuccessCallback`, `PluginApiErrorCallback`, `ServerErrorCallback`), the three error types (`HeadlessApiError`, `PluginApiError`, `ServerError`), an `HttpVerb` enum, a JSON serialization wrapper, and a `Scheduler` helper. You rarely interact with this namespace directly, but its error types appear in every API callback signature.

***

#### `Tebex.Headless`

**Client-side store API for browsing products, managing baskets, and initiating checkout.**

This is the primary API namespace for Unity game clients. 

`HeadlessApi` is the singleton entry point. It provides synchronous and `Task`-based async methods to fetch the `Webstore`, `Category` list, `Package` list, and to create and modify `Basket` objects. 

Note that we use an adapter pattern (`HeadlessAdapter` / `UnityHeadlessAdapter`) which abstracts the HTTP layer so the API logic is testable outside of Unity's runtime.

***

#### `Tebex.Plugin`

**For dedicated server integrations.**

`PluginApi` authenticates with a **secret key** and exposes endpoints for various tasks that are normally performed on a dedicated game server or backend, such as:

* command queue polling, 
* player lookups, 
* payment history, 
* gift card management, 
* coupon management, 
* ban management, 
* and community goal tracking. 

This is intended for use on a dedicated server build or cloud function, not in the game client.

***

#### `Tebex.QR`

**C# QR code generation and decoding**

`QrCode` encodes HTTPS URLs into compact QR data and exposes a `bool[,]` module grid or raw `byte[]` representation for rendering. 

The `Utilities.QrToTexture()` helper in `Tebex.TebexUnity` converts a `QrCode` into a `Texture2D` for display as a UI image or world-space sprite.

***

#### `Tebex.Examples`

**Placeholder classes demonstrating how to structure integrations.**

Contains stub classes intended as starting points for custom integrations. Copy and extend these for your needs. See [Examples](/developers/unity-engine/examples.md)for Unity-specific examples.
