V-Blaze and V-Cloud Online Help

V‑Blaze REST API version 2.0.1


  1. HTTPS is now supported for callback and utterance_callback options. Setting the additional parameter insecure=true allows the callback to make "insecure" HTTPS connections, where successful certificate validation is not required.

  2. The /sysinfo endpoint now provides WebAPI version information.

  3. The default setting for maxconns is now maxstreams + 50 to provide more connection headroom on smaller instances. Additional control is now available for advanced configuration of available connections.


  1. Text (output=text) results provided in zip files now have the .txt extension instead of .json.

  2. Improved callback error logging.

  3. Improved refresh operation against ASR engine restarts.

  4. Added explicit package dependency for zip.
