Connected where it counts.
Closr replaces the CRM, the email tool, and the chat widget rather than syncing with them — so the integration list is short on purpose. What's here is the infrastructure your meetings and conversations actually run on.
Calendars
Two-way sync: Closr reads your busy blocks and writes confirmed meetings back, with the conferencing link attached.
Google Calendar
Two-way sync, event creation, Meet links
Microsoft Outlook
Two-way sync via Microsoft Graph, Teams links
Lark Calendar
Two-way sync for Lark workspaces
Zoom
Meeting creation and calendar availability
Conferencing
Pick one or offer several on the same event type — the invitee chooses and the confirmation carries the right link.
Google Meet
Auto-generated per booking
Zoom
Meeting created on your connected account
Microsoft Teams
Online meeting created via Graph
Campaigns, sequences, and booking confirmations send from your own mailbox, so replies land where you already read them.
Gmail
OAuth send and optional thread sync
Microsoft Outlook
Graph send and optional thread sync
Messaging
Every connected channel arrives in one thread list, attached to the contact record, with an optional AI agent answering.

Three ways to connect what isn't on this list
You do not need us to build the integration for Closr to talk to your stack.
Site snippet
One script for visitor tracking, click capture, and embedded forms on any site you control.
Outbound webhooks
Automations can call your endpoint when an event fires. Sales and Enterprise plans.
Voice API key
Drive the voice agent from your own IVR or web surface instead of the built-in widget. Sales and Enterprise plans.
