Frequently Asked Questions

How do I connect Slack to Calendly?

There's no native integration. To connect them, you will need a middleware tool like Make or n8n.

Is the connection between Slack and Calendly secure?

Yes. This integration typically uses OAuth 2.0, meaning you grant permission via a secure login window. You do not need to share your raw password, and you can revoke access at any time from your Slack security settings.

Is the sync one-way or two-way?

This is typically a one-way sync: Slack → Calendly. Changes in Calendly do not sync back to Slack.

Will existing data in Slack sync to Calendly?

Usually, no. Most native integrations are "forward-looking," meaning they only sync data created or updated *after* you activate the connection. To move historical data, you will likely need to perform a one-time CSV export/import manually.

Can I sync custom fields?

Native integration is limited to standard fields. For custom field mapping, use an automation tool.

Can I add approval steps before syncing?

Native integrations can't do this. For workflows that need human review (e.g., "Manager must approve before creating invoice"), use Relay.app.
