If you manage processes that take minutes or hours — for example deep research, generating long videos, or thousands of prompts in a batch — you probably know the annoyance of having to continuously polling to know when a task finishes. Sound familiar? Google announces a change that flips that flow: event-driven Webhooks in the Gemini API.
What changes with Gemini API Webhooks
Instead of repeatedly asking "is it done yet?", the Gemini API can now push an HTTP POST to your server the moment a task finishes. That means less friction, fewer useless calls, and noticeably lower latency for your app to react in real time.
What does this look like in practice? Imagine a pipeline that processes thousands of prompts or renders long videos: you no longer need to keep sockets open or run cron jobs to check statuses. The result arrives at your endpoint and you can move on to the next step immediately.
