Are Webhooks API supported for Vertex AI batch jobs?

I’m using @google/genai with vertexai: true for batch prediction jobs with GCS input/output.

I’d like to receive batch.succeeded / batch.failed notifications via webhook instead of polling. However, webhooks.create returns 404 in Vertex AI mode:

const client = new GoogleGenAI({ vertexai: true, project: ‘my-project’, location: ‘global’ });
await client.webhooks.create({
name: ‘my-webhook’,
subscribed_events: [‘batch.succeeded’, ‘batch.failed’],
uri: ‘https//example.com/webhook’,
});
// → 404

The Webhooks API docs (https//ai.google.dev/gemini-api/docs/webhooks) seem to cover the Developer API only. Is this correct — webhooks are not available for Vertex AI?

Hello @ioio ,
