Real-Time: Reference

Control phone calls in real-time!

When using real-time, we are the HTTP Client, and you are the HTTP Server. It means that you have to configure an URL we will communicate with to request actions.


The URL is configured in a REALTIME10 object. See the method apps.create.


Real-Time works with both inbound and outbound calls. If you want to start an outbound call, check the method calls.realtime.


We will send POST requests to your server with the call status, and the result of the previous command (if any). Your server must reply with a command, within 5 seconds. As soon as the command is completed, we will POST the result to your server, you reply with another command, and so on.


You control the call in real-time!


POST requests we make to your server are RT.Request:

POST /your.url HTTP/1.1
Host: your.host.here
Accept: */*
Content-Length: 219
Content-Type: application/json

{
   "app":"4346423A",
   "callid":421889,
   "request_hash":"4260XMAQ",
   "cli_name":"",

   "command_result":"",
   "command_error":"",
   "call_status":"UP",

}

And your reply must be a JSON object of RT.Response:
