FaxOut API

Send Fax Web API is based on a single HTTP POST request with multipart/form-data body through which un-rendered fax data is passed to the web. An appropriate response containing request execution result should be returned back to requesting application. The response only says if the fax has been accepted or not. Sending status will be provided to user by email. HTTPS protocol is proposed for using with Send Fax Web API for better security.
