CodeSignal aims to make talent accessible by creating software and standards for assessing the technical skills of software developers. Greenhouse Recruiting's integration with CodeSignal allows your organization to add a CodeSignal Pre-Screen assessment or Tech Screen to a job's interview plan.

Note: In addition to the Greenhouse Recruiting permissions covered in this article, the user enabling this integration for their organization will also need to be a CodeSignal Admin.

In this article:

Configure user setup permissions in Greenhouse Recruiting

In order to enable the Greenhouse Recruiting / CodeSignal integration, you will need the developer permissions Can manage ALL organization’s API Credentials.

Contact a Greenhouse user in your organization with Site Admin level permissions with the additional user-specific permission Can edit another user's advanced permissions to apply the noted developer permissions to your account. Have the user with Site Admin level permissions edit your user account's permissions by navigating to the Configure icon Configure.png > Users > Your Name.


The user with Site Admin level permissions should navigate to the Permissions panel on your user page and expand the Developer Permissions dropdown menu.

Select Can manage ALL organization’s API Credentials so that a check is in each checkbox. When finished, click Save.


Create Harvest API key for the Greenhouse Recruiting / CodeSignal integration

To create a Harvest API key for the integration, click the Configure icon Configure.png in the upper right-hand corner. Navigate to Dev Center on the left-hand panel. From the Dev Center page, click API Credential Management.


From the API Credential Management page, click Create New API Key to generate the API key for CodeSignal.


In the Create New Credential dialog box, make the following selections:

Note: You cannot access the full API key again after clicking I have stored the API Key. If you lose your API key and need to access it later, you must create a new API key, provide it to the integration partner, and then revoke access to the original key.


On the subsequent page, confirm the following permissions are assigned to your new API key:

Once you have obtained your API key, fill out the form at or click here to open a ticket. Please indicate whether you would like the CodeSignal Pre-Screen stage, CodeSignal Tech Screen stage, or both stages added to your account, in which case you’ll provide two API keys.

Note: Do not send the API key in this initial email.

The Greenhouse Support Team will respond with a SendSafely link for you to enter your API key. A notification will be sent to the Greenhouse Support Team after you have entered your API key and they will email you to confirm that your API key has been set up in your account and your integration is enabled.

Note: To verify your identity, the Greenhouse Support Team might request you provide a Support Verification Code before adding the API key to your organization's account.

Select default senders (Optional)

Note: This section is an optional step for CodeSignal Certify users only.

In CodeSignal, under Certify Default Senders, specify a team member as the default sender for each of your certified assessments. This is the individual on whose behalf CodeSignal will specify the assessment is from in the email invitation.

This only applies to candidates who receive an email invitation to take the test directly from CodeSignal or the candidate profile in Greenhouse Recruiting. The individual's email address will not be listed in the email invitation. 

Click Save. The Greenhouse Recruiting / CodeSignal integration configuration is now complete!

Add CodeSignal stage to job’s interview plan

Once the Greenhouse Recruiting / CodeSignal integration is enabled for your organization, you will be able to add the CodeSignal Pre-Screen (formerly CodeSignal Test) or CodeSignal Tech Screen as an Interview stage.

To do this for an existing job, navigate to a job (All Jobs > Job Name) and click Job Setup from the job navigation bar.

From the Job Setup page, navigate to Interview Plan on the left-hand panel. Scroll down the page and click + Add a Stage.

From the Add Stage dialog box, select the CodeSignal stage: CodeSignal Pre-Screen or CodeSignal Tech Screen. When finished, click Add to apply the stage to the job's interview plan.

Send and review CodeSignal Pre-Screen or CodeSignal Tech Screen from Greenhouse Recruiting

When candidates are moved into the CodeSignal interview stage, Greenhouse will display a Send Test link.

Note: When you send a test from Greenhouse Recruiting, the interview instructions are actually sent by CodeSignal.

Select the Pre-Screen assessment or Tech Screen that you want to send, as well as the name of the person who should evaluate the test. The candidate's email address will be auto-populated.

The status of the Pre-Screen assessment or Tech Screen will be viewable in Greenhouse Recruiting (e.g. Sent).

Note: Greenhouse Recruiting updates test scores once every hour, so there may be a small delay between a candidate's completion of a test and the recording of his/her score in Greenhouse Recruiting.

Once the Pre-Screen assessment or CodeSignal Tech Screen is completed, the candidate's score will be recorded in the relevant CodeSignal Pre-Screen or CodeSignal Tech Screen stage, and the grader will be notified via email to review the candidate's result and complete a scorecard in Greenhouse.

Once the grader has completed their scorecard, their overall recommendation for the candidate will also be displayed along with the candidate's score in the CodeSignal Pre-Screen or CodeSignal Tech Screen stage on the candidate's profile in Greenhouse Recruiting.

Click CodeSignal Pre-Screen or CodeSignal Tech Screen within this stage to view a summary of the candidate's scores per task in the test.

Note: The CodeSignal Pre-Screen stage may appear as CodeSignal Test on jobs or reports created before April 2022.

When viewing the summary of results, click View Report to view the candidate's results (including coding replays) in detail on CodeSignal.
