A complete REST API integration toolkit for Unity—the fastest way to connect your projects to backend services with visual testing, automated code generation, and built-in authentication.API Integration Toolkit is an all-in-one Unity Editor solution that dramatically simplifies REST API integration. Instead of manually writing networking code, parsing JSON, managing authentication, and maintaining API clients, simply import your Postman Collection or OpenAPI/Swagger specification and generate production-ready C# API code with a single click.Designed for both indie developers and professional studios, the toolkit provides a visual API Explorer, built-in request tester, automatic model generation, authentication management, response caching, and runtime API testing—all inside Unity. Whether you're connecting to your own backend or third-party services, API Integration Toolkit eliminates repetitive work so you can focus on building your game.Key FeaturesImport APIs from Postman Collection (JSON)Import APIs from OpenAPI/Swagger URLsVisual API Explorer with organized endpoint navigationBuilt-in API request tester inside UnityGenerate strongly-typed C# API clientsAutomatic request and response model generationAsync API methods with UniTask supportSupport for Bearer Token, API Key, and Basic AuthenticationAutomatic authentication token detectionMultiple Base URL managementSecure encrypted credential storageResponse caching with configurable expirationOffline cache fallbackETag and Last-Modified cache validationConfigurable HTTPS enforcement and request timeoutSupport for JSON, form-urlencoded, multipart/form-data, and binary requestsRuntime API Explorer demo for in-game testingAPI specification viewerOne-click project code generationSupport for multiple API collectionsEasy project configuration through ScriptableObject settingsPerfect ForMultiplayer gamesLive-service gamesBackend-integrated mobile gamesUser authentication systemsLeaderboards and player profilesCloud save systemsE-commerce and marketplace integrationsAI service integrationsAnalytics and telemetryCMS-driven applicationsRapid game prototypingInternal development toolsMinimum Unity Version: Unity 2022.3 LTS or higher (including Unity 6.x)Supported Platforms: Windows, macOS, Linux, Android, iOS, WebGL, StandaloneSupported Render Pipelines: Built-in, URP, HDRPProgramming Language: C#Editor Extension: YesRuntime Support: YesNetworking: REST API (HTTP/HTTPS)Supported HTTP Methods: GET, POST, PUT, PATCH, DELETESupported Content Types: JSON, Form URL Encoded, Multipart/Form-Data, BinaryAuthentication: Bearer Token, API Key, Basic AuthenticationCode Generation: Strongly Typed Models, Async API Client, Runtime Test Class, ScriptableObject SettingsAPI Testing: Built-in Editor Request Tester and Runtime API ExplorerCaching: Configurable Response Cache with Offline FallbackCredential Storage: EncryptedMultiple Base URLs: SupportedAutomatic Token Detection: SupportedDemo Scene: IncludedDocumentation: IncludedExternal Dependencies: Newtonsoft Json, Cysharp UniTaskThis package includes documentation and promotional materials generated with AI assistance (ChatGPT, DALL·E).
