Look up the calls and events you need to integrate Nuxie with your app or backend. For a first integration, start with your [SDK's setup guide](/docs/sdks).

## SDK reference

Read customer state, trigger Experiences, and manage access from your app.

**[iOS](/docs/reference/ios)**

Swift interfaces and detailed SDK guides.

**[Android](/docs/reference/android)**

Kotlin configuration, methods, and callbacks.

**[React Native](/docs/reference/react-native)**

JavaScript and TypeScript interfaces.

**[Flutter](/docs/reference/flutter)**

Dart client and native integration.

**[Unity](/docs/reference/unity)**

C# client interfaces.

**[Godot](/docs/reference/godot)**

GDScript calls, results, and signals.

**[Unreal](/docs/reference/unreal)**

C++ and Blueprint interfaces.

## API and event reference

Use the Workspace API to start Experiences from your server and manage workspace resources. The App API handles customer events, profiles, purchases, and access—the same operations used by the SDKs. The [HTTP API guide](/docs/api-reference/rest-api#choose-an-api) explains the host and credentials for each.

**[HTTP API](/docs/api-reference/rest-api)**

Workspace and App API authentication, requests, and responses.

**[Webhooks](/docs/api-reference/webhooks)**

Understand how store notifications keep purchases current in Nuxie.

**[System events](/docs/api-reference/system-events)**

Understand SDK lifecycle and Experience telemetry events.
