Introduction

This document presents information on xStation API communication protocol. The communication protocol of the xStation API uses JSON format.

JSON format used by the server doesn't allow extensions (e.g. comments, other flags). JSON format standardization document is available under the following link: http://tools.ietf.org/html/rfc4627.

The connection is performed by clean socket connection. For real trading SSL connection will be used.

Definitions

The following definitions will be used in this specification document:

• simple type: type, which value is itself: int, int64, string, double, bool;
• j-value (JSON value): any simple type, j-object or j-array;
• j-object (JSON object): a record containing any number of named j-values (pair );
• j-array (JSON array): an array where each element is j-value;
• j-subvalue: j-value which is a component of a j-object.

A j-object can contain zero elements. A j-array can have zero length. The name of j-value can be an empty string.

Encoding of strings is set to UTF-8. In this format the server sends and receives data.

Definition of unix-time:

Unix time, or POSIX time, is a system for describing points in time, defined as the number of milliseconds elapsed since midnight Coordinated Universal Time (UTC) of January 1, 1970.

General data format

Each packet consists of exactly one main, unnamed j-value. The data stream consists of consecutive j–values, with no punctuation.

The main j-value is a j-object containing exactly two j-subvalues which are j-objects. The first j-subobject is named header and consists of at least a field type as a simple type string. This is a packet type. The second j-subobject of the main packet j-object is named data and its content is specific to a given packet type. The specifications for different types of packages are described in the next chapter.

A sample of properly defined packet:

{
	"command" : "login",
	"arguments" : {
		"userId" : 1000,
		"password": "PASSWORD"
	}
}

Communication with the xStation API

There are two IPs, that can be used interchangeably:

• xapia.x-station.eu
• xapib.x-station.eu

Here are the addresses of DEMO and REAL servers:

• DEMO: main port: 5124, streaming port: 5125,
• REAL: main port: 5112, streaming port: 5113.

Both servers use SSL connection.

Communication is established as long as both server and client have opened and connected sockets

For convenience server guarantees that every separate reply to client command returned by server will be separated by two new line characters ("\n").

1. Connection validation

   In order to provide best service for all users xStation API set rules on connection and data send process. If any of the following rules is breached, then connection is closed immediately without server notification.

   List of rules:

   • Every new connection that fails to deliver data within one second from when it is established may be forced to close with no notification,
   • Each command invocation should not contain more than 1kB of data,
   • User should send requests in 200 ms intervals. This rule can be broken, but if it happens 6 times in a row the connection is dropped,
   • Each command should be proper JSON object.

   Exception:

   If the client sends a request that is a valid JSON object, but does not conform to the published API (incorrect command, missing fields, etc.), the response is sent back with the error description but the connection is not closed.

   This rule prevents incorrect messages from reaching further down the processing chain and allows clients to analyze and understand the source of problem.

2. Default login credentials

   Default login credentials can be obtained at: http://developers.xstore.pro/panel/.

3. Input data format

   The input data format is a JSON object that consists of service name and command name. Some commands also require an object of command's arguments.

   If optional prettyPrint field is set to true, an output JSON is printed in human-readable format. prettyPrint field can be omitted.

   {
   	"command": "commandName",
   	"arguments": {
   		"arg1Name": 10,
   		"arg2Name": "Some text",
   		...
   	},
   	"prettyPrint": true
   }

4. Output data format

   The output data format is a JSON object that consists of status and returnData fields if command succeeded, or status, errorCode and errorDescr fields if an error occurred.

   {
   	"status": true,
   	"returnData": JSON value
   }

   or, in case of an error:

   {
   	"status": false,
   	"errorCode": "E123",
   	"errorDescr": "Error description"
   }

5. Time format

   Time is number of milliseconds from 01.01.1970, 00:00 GMT.

6. Floating number format

   In all Floating numbers '.' (period) is used as a decimal separator.

Available commands

Request-Reply commands are performed on main connection socket. The reply is sent by main connection socket.

1. Login

   In order to perform any action client application have to perform login process. No functionality is available before proper login process.

   After initial login, a new session is created and all commands are executed for a logged user until he/she logs out or drops the connection.

   Request:

   Parameters:

   Name	Type	Desc
   userId	Number	userId
   password	String	password
   appId	String	(optional) application ID provided by the xStore Support Team
   appName	String	(optional) application name

   Example:

   {
   	"command": "login",
   	"arguments": {
   		"userId": 100,
   		"password": "PASSWORD",
   		"appId": "test",
   		"appName": "test"
   	}
   }
   

   After successful login the system responds with the status message that can contain the String representing streamSessionId field:

   
   {
   	"status": true,
   	"streamSessionId": "8469308861804289383"
   }
   
   

   Alternatively, when redirect is needed, the system responds with:

   {
   	"status": false,
   	"redirect": REDIRECT_RECORD (optional)
   }
   
   

   Format of REDIRECT_RECORD:

   name	type	description
   mainPort	Number	Main port for communication
   streamingPort	Number	streaming port
   address	String	address that the user should reconnect to in order to login

   Example:

   {
   	"mainPort": 1234,
   	"streamingPort": 1235,
   	"address": "xapia.x-station.eu"
   }
   

   The status of the correct login process is true. If the status is false, REDIRECT_RECORD may be present which defines the server that the user should log into instead of the current one. It is assumed that when using REDIRECT_RECORD data, secure connection (SSL) should be used.

   The streamSessionId field of the string type, if present, is a token that can be used to establish a streaming subscription on a separate network connection. streamSessionId is used in streaming subscription commands.

   streamSessionId is unique for the given main session and will change between login sessions.

2. Logout

   Format of input:

   {
   	"command": "logout"
   }
   

   No returnData field in output. Only status message is sent.
