Guide to authentication for the OpenAI Apps SDK

The OpenAI Apps SDK, introduced by OpenAI, enables developers to integrate their applications with ChatGPT by utilizing custom UI components, API access, and user context persistence, built on the Model Context Protocol (MCP). This integration is facilitated through familiar web standards like OAuth 2.1 and OIDC, with ChatGPT acting as an OAuth client to authenticate users and authorize actions. The process includes dynamic client registration, consent management, and secure data handling, ensuring a standards-based connection between ChatGPT and applications. Developers can choose to either build their own identity layer or use services like Stytch Connected Apps to bridge their existing authentication infrastructure with ChatGPT. The SDK supports structured content and input templates, allowing for interactive and user-friendly experiences within ChatGPT. Key security measures include sandboxing UI components and enforcing authentication with securitySchemes, ensuring secure and controlled access to tools and data. The guide emphasizes the importance of adhering to security and privacy standards while using these tools to create seamless user experiences within ChatGPT.
