Access to the web service

I have a .Net web application and I would like to authenticate users to it using an OTP. By way of examining the Web GUI code, I was able to invoke the web service using the following URL, through either Fiddler or Chrome:
where the "{username}%09{OTP}" is the user's email address + TAB + the OTP, URL-encoded. When I try it from my code or from IE, I always false.

What is the correct way of invoking the service? Do I need to specify anything specific in the request?

Thank you,

    Hello, is a REST api maybe available now?
  • Hello, Yes, a SOAP implementation is available, just call the web interface with the ?soap parameter to see the list of the operation names. For example : The SOAP implementation is compatible with openOTP implementation. Regards,
