Google drive watch channel not sending updates anymore

[Mahit_Mehta_ZTRON]

After the initial successful creation of a watch channel + first webhook message, we no longer receive change webhook messages for about a week now… Furthermore, I have seen 2 other Reddit posts made in the last few days about the same issue. Any help would be welcome!

I have the exact problem. The sync state event is received instantly but changes state event never hits. Sometimes hits after so long which make it unusable for production.

Same issue here:

Google Drive webhooks only send the initial sync, never update… am I missing something obvious?

I’m trying to use Google Drive push notifications with Django and I can successfully create the watch channel I get the initial sync notification but I never receive update notifications for file changes. No errors anywhere, and polling works perfectly. It used to work perfectly, and then suddenly I stopped receiving notifications of changes to my webhook. Stack: Django 5 + Uvicorn, Drive API v3, OAuth (refresh tokens), webhook via ngrok, DB stores channel info. What works: Webhook is reach…

Hey,

Hope you’re keeping well.

Drive API watch channels are temporary and expire after the expiration timestamp returned when you create them, often within hours or days. Once expired, no further webhook notifications are sent, so you need to renew the channel before it expires. Check the expiration field in your channel creation response, and implement a refresh process that re-creates the watch periodically. Also confirm your webhook endpoint is responding with a 2xx status quickly, as repeated failures will stop notifications. You can review logs in your receiving service to ensure requests from Google are not being dropped.

Thanks and regards,
