Webhook delivery stopped for specific account after user reconnect

Hi,

We’re a published Zoom Marketplace app (Timely — time tracking integration) experiencing a webhook delivery issue affecting a specific customer account.

What happened

  • A customer’s Zoom integration was working normally, syncing meetings for all workspace users
  • The workspace admin disconnected and reconnected the integration
  • After reconnecting, no webhooks are being delivered for any users in that account
  • This has persisted for over a month now (since around February 23, 2026)

What we’ve verified on our end

  • :white_check_mark: OAuth token is valid — we can successfully call GET /v2/users/{user_id} and fetch past meetings via the API
  • :white_check_mark: Our webhook endpoint is up and receiving webhooks from other connected accounts without issues
  • :white_check_mark: The issue is isolated to this one account — all other customers are working fine
  • :white_check_mark: No changes were made to our webhook endpoint or event subscriptions

Events subscribed

  • meeting.participant_joined
  • meeting.participant_left
  • deauthorization

Our ask

Could someone from the Zoom team check the webhook delivery logs for our app for this specific account? We believe webhooks stopped being dispatched after the reconnect.

Happy to share app credentials and affected account details via DM or private ticket.

Thanks!
