  $bf->ssl_cert(<path to ssl cert file>);
  $bf->ssl_key(<path to ssl key file>);
  $bf->app_key(<application key>);

  $bf->login({username => <username>, password => <password>});
  ...
  $bf->keepAlive();
  ...
  $bf->logout();

DESCRIPTION

Betfair is an online betting exchange which allows registered users to interact with it using a JSON-based API. This module provides an interface to that service which handles the JSON exchange, taking and returning perl data structures (usually hashrefs). Although there is an option to thoroughly check parameters before sending a request, and a listing of the BETFAIR DATA TYPES is provided below, it requires a level of understanding of the Betfair API which is best gained from their own documentation, available from https://developer.betfair.com/

To use this library, you will need a funded Betfair account and an application key. To use the non-interactive log in, you will also need an SSL certificate and key (in seperate files, rather than a single .pem file). Details of how to create or obtain these, and how to register your certificate with Betfair are also available on the above website. The interactive login does not require an SSL certificate or key and is therefore easier to set up, but Betfair strongly recommend that unattended bots use the non-interactive version.

METHODS

Construction and Setup

new([$parameters])

  my $bf = new WWW::BetfairNG;          OR
  my $bf = WWW::BetfairNG->new();       OR
  my $bf = WWW::BetfairNG->new({
                                ssl_cert => '<path to ssl certificate file>',
                                ssl_key  => '<path to ssl key file>',
                                app_key  => '<application key value>',
                               });

Creates a new instance of the WWW::BetfairNG class. Takes an optional hash or hash reference of configurable attributes to set the application key and/or paths to ssl cert and key files. (These may also be set after instantiation via the accessors described below, but in any case the ssl cert and key need to be present for a successful non-interactive login). The application key is required for most of the API calls, but not for login/logout or 'getDeveloperAppKeys', so if necessary the key can be retrieved from Betfair and then passed to the object using $bf->app_key. If logging in is not possible for some reason, but an active session token can be obtained by other means, this may also be passed to the new object using {session => <session token value>}; the object will then behave as if it were logged in.

Accessors

ssl_cert([<path to ssl cert file>])

  my $cert_file = $bf->ssl_cert();
  $bf->ssl_cert('<path to ssl certificate file>');

Gets or sets the path to the file containing the client certificate required for non-interactive login. Default is '', so this needs to be set for a sucessful login. See Betfair documentation for details on how to create and register client SSL certificates and keys.

ssl_key([<path to ssl key file>])

  my $key_file = $bf->ssl_key();
  $bf->ssl_key('<path to ssl key file>');

Gets or sets the path to the file containing the client key required for non-interactive login. Default is '', so this needs to be set for a sucessful login. See Betfair documentation for details on how to create and register client SSL certificates and keys.

app_key([<key value>])

  my $app_key = $bf->app_key();
  $bf->app_key('<application key value>');

Gets or sets the application key required for most communications with the API. This key is not required to log in or to use 'getDeveloperAppKeys', so it may be retrieved from Betfair and then passed to the object using this accessor. It may also be possible to create the app keys using 'createDeveloperAppKeys', but as this call fails if keys already exist, it was not possible to test this. See Betfair documentation for how to obtain Application Keys using their API-NG Visualiser.

session()

  my $session_token = $bf->session();
  $bf->session('<session token value>');

Gets or sets the current Session Token. Contains '' if logged out. Normally this is set automatically at login and after keepAlive, and unset at logout, but it can be set by hand if necessary.

check_parameters()

  my $check = $bf->check_parameters();
  $bf->check_parameters('<boolean>');

Gets or sets a flag telling the object whether or not it should do a detailed check on the validity of parameters passed to the API methods. If this is set, the parameter hash will be checked before it is sent to the API, and any errors in construction will result in the method call immediately returning '0' and $bf->error being set to a message detailing the precise problem. Only the first error found will be returned, so several iterations may be necessary to fix a badly broken parameter hash. If the flag is not set, any parameters that are a valid hashref or anonymous hash will be passed straight to Betfair, and errors in the construction will result in a Betfair error, which will usually be more general (i.e. cryptic and unhelpful). As some parameter hashes can be quite complicated, there is a performance hit incurred by turning parameter checking on. For this reason, the default is to NOT check parameters, although you should turn it on during development and for debugging.

australian() *DEPRECATED*

  my $is_aus = $bf->australian();
  $bf->australian('<boolean>');

Betfair previously used seperate URLs for Australian racing, and this method implemented the switching between those URLs. From 2016-09-20 the Australian exchange was integrated into the main exchange, making this method unnecessary. From 2017-01-04 calls to the Australian endpoints WILL NO LONGER WORK.

The method has been retained in this version for backwards compatibility, but no longer changes the endpoints. It exists purely to avoid breaking existing third party code. If your application uses this method, you are STRONGLY RECOMMENDED to remove any references to it, as it will be removed in future versions.

error()

  my $err_str = $bf->error();

Read-only string containing the last error encountered. This is not reset by sucessful calls, so the return value of the method needs to be checked to determine success or failure (all methods return '0' if any error is encountered):

  unless ($ret_value = $bf->someCall($parameters) {
    $err_str = $bf->error();
    print "someCall FAILED : $err_str\n";
    <error handling code>
  }

Errors at any stage will populate this string, including connection timeouts and HTTP errors. If the call makes it as far as the Betfair API before failing (for instance, a lack of available funds), the decoded JSON response will be available in $bf->response and may well contain more detailed and descriptive error messages, so this is probably the best place to look if the high level Betfair error string returned in $bf->error() is vague or ambiguous. (This is especially useful in cases where a number of bets are submitted for processing, and one of them fails - this usually makes the whole call fail, and the only way to find the culprit is to dig through the response and find the bet which caused the problem).

response()

  my $resp = $bf->response();

Read-only hash ref containing the last successful response from the API (for certain values of 'successful'). If an API call succeeds completely, it will return a hash reference containing the decoded JSON response (which will be identical to $bf->response), so in this case, $bf->response() is pretty much redundant. If ANY error is encountered, the return value from the API call will be '0', and in this case more details on the specific error can often be found by examining $bf->response(). (Obviously this only works for calls which fail after reaching the API; an HTTP 404 error, for example, will leave the response from the previous successful API call in $bf->response).

API CALLS

These are generally of the form '$return_value = $bf->someCall($parameters)', where '$parameters' is a hash reference (or anonymous hash) containing one or more BETFAIR DATA TYPES (described below), and $return_value is a hash or array reference, again containing one or more BETFAIR DATA TYPES. Many of these data types are straightforward lists or hashes of scalars, but some are quite complex structures. Depending on the call, some parameters may be required (RQD) and others may be optional (OPT). If $bf->check_parameters() is set to 'true', the parameter hash will be checked before it is sent to the API, and any errors in construction will result in the method call immediately returning '0' and $bf->error being set to a message detailing the precise problem. If $bf->check_parameters() is set to 'false' (the default), the parameter hash is sent 'as is' to Betfair, and any problems with it's construction will result in a Betfair error message. Any error in a call, for whatever reason, will result in a $return_value of '0'. In this case, $bf->error() will contain a string describing the error and further details of the error may be found by examining $bf->response().

Session Methods

login({username => 'username', password => 'password'})

  my $return_value = $bf->login({username => 'username', password => 'password'});

Logs in to the application using the supplied username and password. For a successful login, 'ssl_cert' and 'ssl_key' must already be set. Returns '1' if the login succeeded, '0' if any errors were encountered.

interactiveLogin({username => 'username', password => 'password'})

  my $return_value = $bf->interactiveLogin({username => 'username',
                                            password => 'password'});

Logs in to the application using the supplied username and password. This method doesn't use SSL certificates, so it will work without setting those up. However, Betfair STRONGLY RECOMMEND that unattended bots use the non-interactive login ($bf->login()). Returns '1' if the login succeeded, '0' if any errors were encountered.

logout()

  my $return_value = $bf->logout();

Logs out of the application. Returns '1' if the logout succeeded,'0' if any errors were encountered.

keepAlive()

  my $return_value = $bf->keepAlive();

Sends a 'Keep Alive' message to the host. Without this, the session will time out after about four hours. Unlike the SOAP interface, other API calls do NOT reset the timeout; it has to be done explicitly with a 'keepAlive'. Returns '1' if the keepAlive succeeded, '0' if any errors were encountered.

Betting Operations

The descriptions of these methods are taken directly from the Betfair documentation. A listing is given of parameters which can be passed to each method together with their data type (BETFAIR DATA TYPES are described below). Required parameters are marked as RQD and optional ones as OPT. If a parameter is marked as RQD, you need to pass it even if it contains no data, so a MarketFilter which selects all markets would be passed as:

  filter => {}

listCompetitions($parameters)

  my $return_value = $bf->listCompetitions({filter => {}});

Returns a list of Competitions (i.e., World Cup 2013) associated with the markets selected by the MarketFilter. Currently only Football markets have an associated competition.

Parameters

  filter            MarketFilter        RQD
  locale            String (ISO 3166)   OPT

Return Value

  Array Ref         CompetitionResult

listCountries($parameters)

  my $return_value = $bf->listCountries({filter => {}});

Returns a list of Countries associated with the markets selected by the MarketFilter.

Parameters

listCurrentOrders([$parameters])

  my $return_value = $bf->listCurrentOrders();

Returns a list of your current orders. Optionally you can filter and sort your current orders using the various parameters, setting none of the parameters will return all of your current orders, up to a maximum of 1000 bets, ordered BY_BET and sorted EARLIEST_TO_LATEST. To retrieve more than 1000 orders, you need to make use of the fromRecord and recordCount parameters.

                                     });

Place new orders into market. This operation is atomic in that all orders will be placed or none will be placed. Please note that additional bet sizing rules apply to bets placed into the Italian Exchange.

  marketVersion       MarketVersion               OPT
  customerStrategyRef String                      OPT
  async               Boolean                     OPT

Return Value

  customerRef         String
  status              ExecutionReportStatus
  errorCode           ExecutionReportErrorCode
  marketId            String
  instructionReports  Array of PlaceInstructionReport

cancelOrders([$parameters])

  my $return_value = $bf->cancelOrders();

Cancel all bets OR cancel all bets on a market OR fully or partially cancel particular orders on a market. Only LIMIT orders can be cancelled or partially cancelled once placed. Calling this with no parameters will CANCEL ALL BETS.

Parameters

  marketId          String                      OPT
  instructions      Array of CancelInstruction  OPT
  customerRef       String                      OPT

Return Value

  customerRef       String
  status            ExecutionReportStatus
  errorCode         ExecutionReportErrorCode
  marketId          String
  instructionReports  Array of CancelInstructionReport

replaceOrders($parameters)

  my $return_value = $bf->replaceOrders({marketId => <market id>,
                                     instructions => [{
                                               betId => <bet id>,
                                            newPrice => <new price>
                                                     }]
                                       });

This operation is logically a bulk cancel followed by a bulk place. The cancel is completed first then the new orders are placed. The new orders will be placed atomically in that they will all be placed or none will be placed. In the case where the new orders cannot be placed the cancellations will not be rolled back.

Navigation Data for Applications

This has only one method (navigationMenu()), which retrieves the full Betfair navigation menu from a compressed file which is updated every five minutes.

navigationMenu()

  my $menu = $bf->navigationMenu()

Returns a huge hash containing descriptions of all Betfair markets arranged in a tree structure. The root of the tree is a GROUP entity called 'ROOT', from which hang a number of EVENT_TYPE entities. Each of these can have a number of GROUP or EVENT entities as children, which in turn can have GROUP or EVENT children of their own. EVENTs may also have individual MARKETs as children, whereas GROUPs may not. MARKETs never have childen, and so are always leaf-nodes, but be aware that the same MARKET may appear at the end of more than one branch of the tree. This is especially true where RACEs are concerned; a RACE is yet another entity, which currently may only hang off the EVENT_TYPE identified by the id '7' and the name 'Horse Racing'. A RACE may only have MARKETs as children, and these will typically also appear elsewhere in the tree. Takes no parameters (so it's all or nothing at all).

Return Value

  children          Array of EVENT_TYPE
  id                Integer (always '0' for ROOT)
  name              String  (always 'ROOT' for ROOT)

Heartbeat API

This Heartbeat operation is provided to allow customers to automatically cancel their unmatched bets in the event of their API client losing connectivity with the Betfair API.

heartbeat($parameters)

  my $return_value = $bf->heartbeat({preferredTimeoutSeconds => <timeout>});

This heartbeat operation is provided to help customers have their positions managed automatically in the event of their API clients losing connectivity with the Betfair API. If a heartbeat request is not received within a prescribed time period, then Betfair will attempt to cancel all 'LIMIT' type bets for the given customer on the given exchange. There is no guarantee that this service will result in all bets being cancelled as there are a number of circumstances where bets are unable to be cancelled. Manual intervention is strongly advised in the event of a loss of connectivity to ensure that positions are correctly managed. If this service becomes unavailable for any reason, then your heartbeat will be unregistered automatically to avoid bets being inadvertently cancelled upon resumption of service. you should manage your position manually until the service is resumed. Heartbeat data may also be lost in the unlikely event of nodes failing within the cluster, which may result in your position not being managed until a subsequent heartbeat request is received.

Parameters

  preferredTimeoutSeconds  Integer      RQD

Return Value

  actionPerformed          ActionPerformed
  actualTimeoutSeconds     Integer

Race Status API

The listRaceDetails operation is provided to allow customers to establish the status of a horse or greyhound race market both prior to and after the start of the race. This information is available for UK and Ireland races only.

listRaceDetails($parameters)

  my $return_value = $bf->listRaceDetails();

Search for races to get their details. 'meetingIds' optionally restricts the results to the specified meeting IDs. The unique Id for the meeting equivalent to the eventId for that specific race as returned by listEvents. 'raceIds' optionally restricts the results to the specified race IDs. The unique Id for the race in the format meetingid.raceTime (hhmm). raceTime is in UTC.

Parameters

  meetingIds     Array of Strings     OPT
  raceIds        Array of Strings     OPT

Return Value

  ArrayRef       RaceDetails

BETFAIR DATA TYPES

This is an alphabetical list of all the data types defined by Betfair. It includes enumerations, which are just sets of allowable string values. Higher level types may contain lower level types, which can be followed down until simple scalars are reached. Some elements of complex data types are required, while others are optional - these are denoted by RQD and OPT respectively. Simple scalar type definitions (Long, Double, Integer, String, Boolean, Date) have been retained for convenience. 'Date' is a string in ISO 8601 format (e.g. '2007-04-05T14:30Z').

THREADS

Because the betfair object maintains a persistent encrypted connection to the Betfair servers, it should NOT be considered 100% thread-safe. In particular, using the same $bf object to make API calls across different threads will usually result in disaster. In practice, there are at least two ways to solve this problem and use WWW::BetfairNG safely in threaded applications:-

'Postbox' Thread

If simultaneous or overlapping calls to betfair are not required, one solution is to make all calls from a single, dedicated thread. This thread can wait on a queue created by Thread::Queue for requests from other threads, and return the result to them, again via a queue. Only one $bf object is required in this scenario, which may be created by the 'postbox' thread itself or, less robustly, by the parent thread before the 'postbox' is spawned. In the latter case, no other thread (including the parent) should use the $bf object once the 'postbox' has started using it.

Multiple Objects

If you need to make simultaneous or overlapping calls to betfair, you can create a new $bf object in each thread that makes betfair calls. As betfair sessions are identified by a simple scalar session token, a single login will create a session which CAN be safely shared across threads:-

  use WWW::BetfairNG;
  use threads;
  use threads::shared;

  my $parent_bf = WWW::BetfairNG->new({
                                       ssl_cert => '<path to ssl certificate file>',
                                       ssl_key  => '<path to ssl key file>',
                                       app_key  => '<application key value>',
                                       });
  $parent_bf->login({username => <username>, password => <password>})
    or die;
  my $session :shared = $parent_bf->session();

  my $child = threads->create(sub {
    # Create a new bf object in the child - no need for ssl cert and key
    my $child_bf = WWW::BetfairNG->new({app_key  => '<application key value>'});
    # Assign the shared session token - $child_bf will then be logged in
    $child_bf->session($session);

        # Make any required API calls in the child using $child_bf
  });

  # Freely make API calls using $parent_bf

  $child->join;
  $parent_bf->logout; # Logs out any children using the same session token
  exit 0;

In particular, keepAlive calls only need to be made in one thread to affect all threads using the same session token, and logging out in any thread will log out all threads using the same session token.
