verify_signature uses tolerance=300 seconds by default.\n\nFix status: documented_behavior\n\nMisleading approaches:\n- Verifying json.dumps(request.json) instead of the raw body (re-serialization changes bytes).\n\nLimitations:\n- Derived from SDK source/docs on main (v3.19.2, 2026-09-23); no issue thread read.\n\nOther error fragments:\n- Webhook timestamp is too old\n- Webhook timestamp is too new\n- Invalid webhook timestamp format\n- The webhook secret must either be set using the env var, OPENAI_WEBHOOK_SECRET, on the client class, OpenAI(webhook_secret='123'), or passed to this function\n\nEvidence (public sources, summarized;
