Building Stateful Agentic Apps with the Gemini Interactions API

Traditional LLM integrations force developers to act as state managers. Between manually maintaining bloated history arrays, persisting multi-turn conversation context across distributed backends, and writing glue code for tool execution loops, building reliable autonomous workflows often feels more like database plumbing than agent engineering.The Gemini Interactions API fundamentally shifts this paradigm by introducing native, server-side statefulness and unified agent orchestration. In this workshop, we will break down the underlying architecture of the Interactions API and explore the client.interactions interface. Moving beyond standard prompt-and-response patterns, we will demonstrate how native state tracking, persistent interaction chaining, and integrated tool invocation eliminate boilerplate and simplify production agent architecture.Key TakeawaysHow the Gemini Interactions API natively maintains conversational state and context history without manual token management or client-side storage layers.Implementing the client.interactions interface to orchestrate autonomous multi-step tool execution loops.Architectural best practices for building scalable, stateful agentic applications on Google Cloud with drastically reduced code complexity.
