Candidate API - Overview

Today, organizations use many tools in addition to their applicant tracking system (ATS) to recruit and hire top talent. The ability to import and export candidate and application data in real time from Cornerstone’s recruiting solution to point solutions is a must for most clients. Having a reliable, easy to use externally facing candidate API will enable clients to maintain data integrity and get the most return from each point solution.

Cornerstone's Candidate APIs provide the ability to get a requisition's full application workflow, including prescreening and compliance questions, disclaimers, notes, and attachments, and then create an application and candidate in your Cornerstone portal. Applications can be posted in a complete or incomplete status. If incomplete, recruiters can invite candidates to finish their application within Cornerstones. Candidates can apply for positions through CAPI that are only on internal career sites (ICS).

Candidate API includes the following endpoints:

  • Get Application Workflow - This endpoint retrieves a requisition’s full application workflow, including action items that were previously irretrievable via the legacy Job Application API like Prescreening questions, compliance questions, disclaimers, and notes.
  • Post Candidate and application - This endpoint posts a candidate and application to your Cornerstone portal.

These externally facing endpoints are available for both clients and vendors to utilize. With the Candidate API (Early Adopter), the new Get Application Workflow and Post Candidate and Application endpoints enable clients to develop end-to-end integrations with recruiting solutions like chat bots, job boards, candidate relationship management solutions (CRM), marketing tools, and more.
