Using iPi Integration Add-on

Command Syntax

Commands are strings based on JSON syntax. Commands are submitted via JSON requests that include command name and may optionally include command arguments.

The response is also JSON string. The response include success flag. In case of error the response include error message. In case of success the response may optionally include result that is JSON object.

Long actions (recording, background evaluation, etc.) initiated by commands generate asynchroneous events on action completion. Event is described by JSON string that include event name and may include optional arguments, depending on type of event.

SYNOPSIS 

// Request for command without arguments
{
    "command": "<command_name_string>"
}
 
// Request for command with arguments
{
    "command": "<command_name_string>",
    "arguments": 
    {
        <arguments_list_json_string>
    }
}
 
// Simple response in case of success
{
    "success": true
}
 
// Response including command result field in case of success
{
    "success": true,
    "result":
    {
      <result_json_string>
    } 
}
 
// Response in case of error
{
    "success": false,
    "error": "<error_message_string>"
}
 
// Event without arguments
