Gemini API Webhooks Eliminate Polling for Long Jobs

The Gemini API now supports event-driven Webhooks, a push-based system designed to eliminate inefficient polling for long-running jobs like batch processing, long video generation, or Deep Research tasks. Previously, developers had to continuously call GET operations to check if a job was complete, adding latency and complexity. Now, the Gemini API sends a real-time HTTP POST payload directly to your server the moment a task finishes. This is critical as Gemini shifts toward more complex, agentic workflows that can take minutes or hours. Google built this feature for reliability and security, adhering to the Standard Webhooks specification. You can now architect more robust and efficient event-driven systems on Gemini, simplifying code and reducing operational costs.
