About the Tenant ID: The tenant-id parameter in these URLs should be replaced with a unique identifier of your choice. This ID is not provided by Greenhouse and is not generated by StackOne. You can use any unique value (e.g., your company name such as example-inc or acme-corp). This parameter is used by Greenhouse to create uniquely routed endpoints and distinguish between different integrations. Choose a value that makes sense for your organisation and use it consistently across all endpoints.

Greenhouse reviews applications on the first Monday of every month. A member of their Partnerships team will contact you with next steps.

​

Provider Side Setup

​

StackOne Configuration

1

Navigate to enable the Greenhouse at StackOne

Go to the ATS category on the Integrations page and enable Greenhouse.

2

Enable and Configure Greenhouse in StackOne

Fill out the necessary fields in the Greenhouse - Configuration modal:

• Authentication Type - Select Public + Partner API or Partner API to integrate with Greenhouse (for Assessment/Background Check integration).
  Difference between Public API & Partner API

  • Public API: Access to the StackOne Unified APIs, excluding the Assessments and Background Checks Unified API and its features.
  • Partner API: Access to the Assessments and Background Checks Unified API and its features, but not other StackOne Unified APIs. This allows you to integrate your provider's partner app with StackOne.
  • Public + Partner API: Access to all StackOne Unified APIs, including the Assessments and Background Checks Unified API and its features.
  • If you select Public + Partner API, the hiring team’s data will be included in the webhook notification.
    
  • If you select Partner API, the hiring team’s data will not be included in the webhook notification.
• Partner Category - Select the appropriate category based on your integration’s classification as a partner for Greenhouse. e.g.: Assessments or Background Checks
• Package’s List Endpoint URL - Implement and provide an endpoint to StackOne that StackOne will use to retrieve the list of packages when the recruiter wants to send a test to a candidate. Implement the following POST endpoint:
  Copy

  Ask AI

  curl --location 'https://your-domain.com/<route-to-the-post-endpoint>' \
  --header 'Content-Type: application/json' \
  --header 'x-stackone-signature: string' \
  --header 'Authorization: Basic <base64encoded-api-key>' \
  --data '{
      "account_id": "456551489512493411",
      "provider": "greenhouse"
  }'
  

  The expected response of the POST endpoint (list of packages). Refer to:
  • List Assessments Packages
  • List Background Check Packages
  Enter the endpoint into the designated field:
  Copy

  https://your-domain.com/<route-to-the-post-endpoint>
  

• Partner’s Username - You will receive the username from Greenhouse support as mentioned in the previous step.
• Partner’s Password - The password will also be provided by Greenhouse support as mentioned in the previous step.
• Package ID - If you do not have the Package’s List Endpoint URL, you can specify a particular package ID that will be visible to the recruiter when they wish to send the test to the candidate.

How is the Package's List Endpoint URL different from a Static Package ID?

The Package's List Endpoint URL allows StackOne to fetch a list of available packages from your system, while the Static Package ID is fixed and available for users to select on the provider's side.

When you have a Package's List Endpoint URL
A list of packages will be available to select in Greenhouse.

When you have a Static Package ID
A static package ID will be available to select in Greenhouse.

At least one field is necessary for making packages available in the Provider's UI. Preference will be given to the Package's List Endpoint URL, even if both fields are configured.

Click on the Confirm or Save Changes button to enable Greenhouse, which allows end-users to link their accounts via the StackOne Connector Hub.

Add a Webhook

Navigate to the Webhooks page, click on Add webhook and fill out the form:

• Name: Enter your webhook with a recognisable name.
• URL: Enter the URL where the webhook will send the notification of the enabled events.

Click the Confirm and Save buttons to add the webhook.

How will the results of the assessment/background check be displayed to the user in Greenhouse?
