Introduction to Gemini API Webhooks
The Gemini API has introduced event-driven Webhooks, a push-based notification system that eliminates the need for inefficient polling. This feature is designed to make it easier and more efficient to build complex, long-running agentic applications. With Gemini shifting toward agentic workflows and high-volume processing, operations can take minutes or even hours. Webhooks provide a reliable and secure way to receive real-time notifications when a task is completed.
How Webhooks Work
The Gemini API can push a real-time HTTP POST payload to a server the instant a task finishes. This implementation strictly adheres to the Standard Webhooks specification, ensuring idempotency and preventing replay attacks. Every request is signed using webhook-signature, webhook-id, and webhook-timestamp headers. Webhooks can be configured globally at the project level or overridden dynamically on a per-request basis. For example, you can dynamically configure a webhook for a batch task using the Python SDK.
