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.
