Steps
Authenticate API requests using your account's secret API key
Create a Candidate record with the applicant's identifying information
Send the candidate a hosted invitation to collect consent and PII, or create a report directly if the required PII is already on file
Register a webhook URL in the account's developer settings and subscribe to background-check lifecycle events (e.g. candidate created, invitation completed, report created, report completed)
On each incoming webhook, verify the X-Checkr-Signature header (an HMAC-SHA256 hash computed with your API key) before trusting the payload
Known gotchas
A background check emits a sequence of separate webhook events rather than one single final callback, so handlers must track state across events
Signature verification requires recomputing the HMAC-SHA256 hash over the raw request body and comparing it to X-Checkr-Signature
Report objects are asynchronous — a report is not immediately available at candidate-creation time and must be fetched or awaited via webhook
