An integration disconnected itself — why?

Every integration lives on Settings → Integrations — Airtable, Google Calendar, Google Docs, Google Drive, HubSpot, Jira, Notion, Outlook Calendar, Salesforce, and Slack.

If one that was working suddenly shows as disconnected, it's almost always one of these:

The access token expired or was revoked

OAuth tokens can be revoked by the other side — the connected app's admin, an IT policy, or the provider itself after a long period of inactivity. Meetbook can't refresh a token that's been revoked upstream; you'll need to reconnect.

The account that connected it left, or lost access

Integrations are tied to whichever account authorized them. If that person's access to the third-party app (Slack workspace, Notion workspace, Salesforce org) was removed, the connection breaks from that side.

A password or 2FA change on the connected account

Some providers invalidate existing app authorizations when the account's login credentials change. Reconnecting re-establishes it.

Fixing it

Go to Settings → Integrations, find the disconnected app, and click Connect again — this re-runs the same authorization flow as the first time. Nothing already delivered through the integration is lost; only new meetings going forward are affected until it's reconnected.
