Add Human Approval with Relay

Even with a native connector, add approval gates for high-impact sync operations.

  1. 1 A record is ready to move from Greenhouse to Calendly
  2. 2 A reviewer gets the payload preview and business context
  3. 3 The reviewer approves or rejects with reason
  4. 4 Only approved records are written to Calendly

Relay works best when mistakes are expensive:

  • - Finance workflows (refunds, invoices, reconciliation)
  • - Compliance-sensitive updates (audit-ready approvals)
  • - Revenue operations changes (ownership, routing, deal updates)

Frequently Asked Questions

How do I connect Greenhouse to Calendly? ▼

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

Is the connection between Greenhouse 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 Greenhouse security settings.

Is the sync one-way or two-way? ▼

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

Will existing data in Greenhouse 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.

Why does Candidate schedules interview, but the event doesn't link to the Candidate Profile in Greenhouse.? ▼

This is a known issue (~85% of users). Common cause: Email Mismatch (Personal vs Work). Typical fix time: 5 minutes.

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.
