From ATS order to webhook: a clear integration path

Enterprise TA teams do not want another portal as the system of record. They want screening to appear where offers and joiners already live—the ATS or HRIS.

A durable pattern looks like this: (1) recruiter selects a Clarynix package on the candidate record, (2) your integration creates an order via API with an idempotency key, (3) the candidate receives an invite, (4) status webhooks update the ATS as checks progress, (5) a final outcome event closes the loop for compliance review.

Design for retries. Network failures happen. Idempotency keys and signed webhooks prevent duplicate cases and forged events. Log delivery attempts so operations can see whether a stuck status is Clarynix-side or consumer-side.

Keep PII minimised in events. Webhooks should carry case identifiers, status, and high-level outcomes—not full document payloads. Pull detail through authenticated APIs when a reviewer needs evidence.

During onboarding, map three moments only: order created, candidate invited, case completed. Expand later. Teams that start with twenty event types rarely finish the first go-live.
