API

What You Can Do with the CCSS API

CCSS offers a REST API for integration with ATS systems, HRIS platforms, LMS platforms, and custom HR tools.

Automated Assessment from Your ATS

Send a candidate for assessment directly from your ATS. With a single API call, you create a test session and the candidate receives an invitation automatically.

Real-Time Results

Receive test results as soon as the candidate finishes. Webhook notification or polling — choose whichever suits you best.

Programmatic AI Reports

Generate AI reports programmatically and embed them in your system. You receive structured data and formatted report text.

Profile Matching API

Use the matching algorithm to automatically rank candidates. Define the ideal profile and the API returns a list of candidates sorted by compatibility.

Webhook Notifications

Get notified about every event in the system: completed test, generated report, changed candidate status. Real-time integration without polling.
