V0 Platform Webhooks Not Firing At All (API + UI)

Retrying this because it’s now blocking and urgent. Has anyone actually gotten the v0 Platform webhooks to fire in practice?

I can create hooks without issues (per docs). I’ve subscribed to the obvious events (chat.updated, message.created, message.updated) and even tried expanding that set to every possible event. No matter what I do, nothing is delivered.

I’ve tested multiple endpoints:

I’ve tried every trigger I can think of:

  • Editing an existing message, sending a new message, updating the chat

  • Actions performed both via API (POST /chats/{chatId}/messages, async mode) and via the UI

  • Assistant-generated messages as well

Absolutely nothing arrives at the webhook in any of these cases.

I also toggled chat visibility (private → unlisted → public) just in case. No difference.

At this point I need clarity: is there an outage, a scope/plan limitation, or a hidden constraint (e.g., only API-originated events, team-only contexts, or specific event names) that prevents webhooks from firing? If webhooks are supposed to be live, can someone share a minimal, currently-working example (event list + payload we should expect), and confirm which events are guaranteed to fire right now?

As someone willing and planning to spend several thousand dollars a year on v0, this is very frustrating.

P.S: As a temporary workaround, I even tried queuing messages as one would via the UI, but via the API in my test. They are not queued, they are just sent in bulk and this kinda messes up a series of messages sent in quick succession and also the generation process.

ANY kind of help is appreciated. I tried posting here, reaching out via ticket, reaching out via twitter comment, reaching out via a livestream, reaching out via twitter DM to employees, reaching out via email and gotten ZERO responses anywhere.
