Steps
In the Checkr dashboard under Account > Webhooks, register your endpoint URL; Checkr will send POST requests signed with an HMAC-SHA256 signature in the X-Checkr-Signature header.
Verify the signature by computing HMAC-SHA256 of the raw request body using your webhook secret and comparing the hex result to the X-Checkr-Signature value.
Parse the event type from the payload; key events include 'report.completed', 'report.disputed', and 'adverse_action.pre_adverse_action_sent'.
When a report.completed event has result = 'consider', initiate pre-adverse action: POST /v1/adverse_actions with a JSON body containing report_id, adverse_action_reasons (an array of reason objects), and optionally scheduled_at to set the waiting period before final action.
Wait the legally required period (minimum 5 business days under FCRA) before finalizing; Checkr can manage this timer if you pass the appropriate scheduled_at date.
If no dispute is received, Checkr fires the adverse_action.adverse_action_sent event when the final action is taken; update your records accordingly.
Known gotchas
Adverse action workflows have strict FCRA timing requirements; the pre-adverse action notice must be sent before the final decision, and candidates must have time to dispute — do not skip or shorten this process.
Adverse action reasons must correspond to the specific screening type that generated the 'consider' result; using generic or unrelated reasons does not satisfy FCRA adverse action notice requirements.
Checkr webhooks may be delivered out of order or more than once; use the report status from a GET /v1/reports/:id call to confirm state before acting rather than relying solely on webhook order.
