You can use CodeSignal and Greenhouse together to both send candidates coding assessments and receive the scores in Greenhouse. To implement this integration, you need to authorize CodeSignal to use your Greenhouse account. 

The Greenhouse integration with CodeSignal only needs to be completed by ONE user from your company. 


  • You must be logged in to your CodeSignal account.
  • You must have a CodeSignal user type of Admin.
  • You must be logged in to your Greenhouse account.

Once the Greenhouse support team has uploaded this key to your Greenhouse account, CodeSignal Test will be one of the available options when you're creating an interview plan in Greenhouse. 

14. For CodeSignal Certify users only: 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 we 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. 
  • The individual’s email address will NOT be listed in the email invitation.

15. Click Done. Set up in CodeSignal is now complete!
