    Updates

This October, we made improvements webhooks and our dashboard analytics.

  • Webhook updates: Add custom headers and debug events more easily.
  • Dashboard analytics: Clearer usage numbers by time period and project.
  • Messaging app example: Build a Slack-like chat with AI & human teammates.

Upgrade now

To use the latest features, update your packages with the following command.

$npx liveblocks upgrade

If you were previously on Liveblocks 3.17 or below, make sure to follow our upgrade guides before updating.

Webhook updates

We’ve updated a number of features around webhooks in the dashboard. Add headers your receiver expects, send example events to a Liveblocks-hosted test endpoint, and inspect exactly what was delivered.

Custom headers

If your webhook receiver sits behind an API gateway or expects an API key, you can now add custom HTTP headers when creating or editing an endpoint in the dashboard. Previously, custom headers could only be set with the Management API. Each endpoint supports up to five custom headers, sent with every webhook request.

Test endpoint

You can now send example events to a Liveblocks-hosted test endpoint. This makes it easier to test your webhook receiver without having to deploy your own server. Events will be delivered to the test endpoint instead of your application, and you can inspect the response body to see exactly what was delivered.

Easier debugging

We’ve also refined the webhook event details view. You can resend an event from the event itself, open any attempt to view its response body, and copy the message ID.

Update your IP whitelist

Webhooks are no longer sent from a fixed set of IP addresses. If your endpoint only accepts traffic from our previously published IP addresses, update your firewall to allow any IP address, and use signature verification to confirm requests come from Liveblocks.

Coming soon

All the work above is part of our project to create our own webhook delivery engine, rather than relying on a third-party service. Webhooks will continue working seamlessly for you, with no code changes required on your end. Stay tuned for more details!

Dashboard analytics

It’s now easier to understand your project’s activity in the dashboard. When you select a period on a project’s overview, each card updates to match it, and the subtitle explains how it was calculated. Comments, notifications, and connections show the total for the period, active users and rooms show the latest day, week, or month, and peak connections show the highest value.

Your browser does not support the video tag.Updated dashboard

To dig deeper, click “View usage” on a project’s overview to open the usage page for that project, keeping the same period and interval. The active users and peak connections tooltips now describe what each metric measures, and the header shows your team and project, making it easier to switch back to all projects.

Messaging app example

We’ve added a new example showing how to build a Slack-like messaging app with Feeds, Storage, and Presence—no database needed, as Liveblocks stores everything. Each workspace is a room, with channels kept in Storage, and each channel’s messages and direct messages stored in feeds.

Your browser does not support the video tag.Messaging app example

Our Messaging App example

Messages support rich text and @-mentions, and mentioning the AI teammate streams a reply into a thread. Each user also has a personal activity feed that powers unread badges for direct messages, mentions, and thread replies.

Try the example

Minor improvements

  • Fixed unread inbox notification counts not updating when receiving replies in connected rooms in @liveblocks/react.
  • Fixed unread inbox notification counts not updating immediately when marking a thread as read in @liveblocks/react.
  • Fixed LiveText reconnect convergence with pending edits in @liveblocks/client, including lost acknowledgements, repeated reconnects, and queued edits.
  • Webhook messages waiting to be delivered now show as “Scheduled” instead of “Pending” in the dashboard.
  • Documented the limits for webhook custom headers and rate limits in the Management API reference.
  • New customer story: Why Windmill builds everything multiplayer.

Upgrade

To use these latest features, update your packages with:
