Generating your Greenhouse API key (v2 Integration)
To generate your Greenhouse API key, follow these steps:
- Log into your Greenhouse account.
- Click the settings (gear) icon, then go to Dev Center.
- In the left sidebar, click API Credentials.
- Select the Harvest v3 (OAuth) tab.

- Click Create new API credentials.
- In the API type dropdown, select Harvest V3 (OAuth).
- In Description, enter something identifiable — e.g. HackerEarth

- Click View and store credentials.
- Copy the Client key and Client secret shown on screen. Important: The client secret is shown only once. Copy and store both values somewhere safe — if you lose the secret, you'll need to rotate the credential.
- Click I have stored the client credentials.
- Back on the credential's Settings tab, under Manage scopes, make sure Harvest is checked, then click Save.
