      I am receiving a persistent 400 Bad Request (Empty Body) specifically on the v1/placeOrder endpoint.

      Technical Evidence:

      • Client Code: AACG145520
      • API Key: PIyJDlNk
      • Public IP: 185.194.101.49 (Whitelisted)
      • WAF Support ID: 11287828653050396397
      • Timestamp: Mon, 20 Apr 2026 09:44:38 GMT

      Observations:

      • The same IP and headers work perfectly for 'searchScrip' (returns 200 OK).
      • The v1/placeOrder endpoint returns an empty 400 response.
      • Testing with v3/placeOrder returns a 200 OK but with a "Request Rejected" HTML page containing the Support ID above.

      This points to a security block or segment restriction on the F5 WAF specifically for the order placement path. Please check the logs for the Support ID and enable 'Write/Trading' permissions for this API key.
