Gemini API Event-Driven Webhooks

Google has launched event-driven webhook support in the Gemini API, enabling developers to build complex long-running agentic applications without polling. Instead of repeatedly checking job status, developers register a webhook URL and Gemini calls it automatically when long-running tasks complete — reducing latency, cutting infrastructure overhead, and making async AI pipelines significantly simpler to build.

key features
  • 01Register a webhook URL with the Gemini API and receive automatic callbacks when long-running jobs complete — eliminates polling loops and reduces wasted compute for agentic pipelines
  • 02Purpose-built for complex, long-running agentic applications: model fine-tuning jobs, batch inference, async generation tasks, and multi-step reasoning workflows that take minutes to hours
  • 03Drop-in improvement for existing Gemini API integrations — standard HTTP webhook pattern, works with any backend infrastructure, no SDK changes required
