Proctorio Result Webhooks (v2/v3)
After an exam attempt is submitted, Proctorio POSTs an HMAC-signed JSON webhook to the integrating platform's endpoint carrying the attempt id, user id, an overall suspicion score, submission metadata, and a set of behavioral flags (unfocus, clipboard, browser resize, multiple faces, leaving the exam area, speaking, AI-assistance, printing, screenshot, hardware change, external action, webcam obscured, mobile phone, and more, each weighted 0-1). Two payload versions are documented (v2 and v3). This is server-to-endpoint HTTP delivery over HTTPS, not a WebSocket; the payload can be re-emitted from the Review Center Export Options tab when behavior settings change. Payload shape is taken from Proctorio's official .NET client (Webhooks/Requests/V2 and V3).
