API Integration Toolkit

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.
