Frequently Asked Questions

Does Slack integrate directly with Greenhouse?

Yes, Slack has a native integration with Greenhouse. It is available directly within the Slack app marketplace.

Is the connection between Slack and Greenhouse 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 → Greenhouse. Changes in Greenhouse do not sync back to Slack.

Will existing data in Slack sync to Greenhouse?

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.
