Steps
Authenticate to the SmartRecruiters Customer API with OAuth 2.0 credentials tied to an Admin role (or with the 'Manage webhooks' permission enabled) and the required access scopes
Call POST /subscriptions with a callback URL and the array of event names to receive — pipeline/status-change and application-creation events are listed under the Callbacks tab of that endpoint in the API reference
Optionally set callbackAuthentication (a custom header name/value) and/or generate a secret key to enable HMAC SHA-256 signature verification of incoming notifications
Complete the activation handshake: SmartRecruiters POSTs an X-Hook-Secret header to your callback URL, and your endpoint must respond HTTP 200 echoing back the same header/value before SmartRecruiters confirms activation with a 204
Respond to each subsequent notification with HTTP 202 within 5 seconds for it to count as successfully delivered
Trigger a real stage/status change on a test candidate and confirm your endpoint receives, verifies, and acknowledges the notification
Known gotchas
Notifications carry only resource IDs, not full candidate/application data, and delivery ignores access-group restrictions — your API credentials' access group can still block retrieval of the full resource by that ID
The subscription remains inactive until the X-Hook-Secret handshake is completed exactly (echoing the same header value) — this is a common setup mistake
Failing to return 202 within 5 seconds on ordinary notifications (distinct from the one-time activation handshake) causes SmartRecruiters to treat the delivery as failed
