Application

API_NG_TestBed is a Delphi application for testing an interface function library for the Betfair API-NG.

It was built using Delphi XE but should be backward compatible with most earlier versions.

PLEASE NOTE: You will need to provide your own Betfair Application Key in order to use this test application (see Application Key section below).

The API interface library consists of 3 files:

  • LBS_BetfairAPINGClasses.pas
  • LBS_BetfairAPINGUtils.pas
  • LBS_BetfairAPINGFunctions.pas

The interface uses JSON-RPC protocol and supports the following API-NG functions:

  • listCompetitions
  • listCountries
  • listCurrentOrders
  • listClearedOrders
  • listEvents
  • listEventTypes
  • listMarketBook
  • listMarketCatalogue
  • listMarketProfitAndLoss
  • listMarketTypes
  • listTimeRanges
  • listVenues
  • placeOrders
  • cancelOrders
  • replaceOrders
  • updateOrders
  • getAccountFunds
  • getAccountStatement

Application Key

In order to use the test application the user must provide their own Betfair Application Key. Locate the following section of code in frmMain.pas and enter your key values here:

  const
    {**************************}
    { Betfair application keys }
    {**************************}
    cBetfair_AppKey         = 'EnterAppKeyHere' ;
    cBetfair_AppKey_Delayed = 'EnterDelayedAppKeyHere' ;

Disclaimer

Betfair provides this Delphi Library ‘as is’. There are no guarantees as to the functionality of the application, Betfair will not be liable for any bets placed erroneously as a result of misuse of the application or due to bugs in the application.

JSON Popup Form

In order to support debugging/testing of the raw JSON request/response strings, a facility for displaying these is provided via a popup form. To enable this feature the variable LBS_BetfairAPINGFunctions.gDebugJSON must be set to true. There is a checkbox at the top of the test application for this purpose.

Superobject

This interface library implementation makes use of the excellent Superobject classes for JSON parsing and construction. Detailed information and licensing for Superobject can be found here.
