Finance::BankValUK - Perl extension for accessing Unified Software's bankValUK web services


  use Finance::BankVal::UK qw(&bankValUK);

  $result = &bankValUK(@params);

  ============= or for OO =============

  use Finance::BankVal::UK;

  my $bvObj = Finance::BankVal::UK->new();
  $result = $bvObj->bankValUK(@params);


This module handles all of the restful web service calls to Unified Software's BankValUK service. It also handles fail over to the back up services transparently to the calling script. It can be called either in a procedural sense or an OO one (see synopsis)

The exposed method &bankValUK(); takes a number of parameters including;

1: Format - the response format (either xml, json or csv)

2: Sort code - 6 digit number either 00-00-00, 00 00 00 or 000000

3: Account no. - 6 to 12 digit (unseperated i.e. 00000000)

4: UserID - available from

5: PIN - available from

(UserID and PIN are available from

The order of the parameters must be as above although supplying an account number is optional. The UserID and PIN can also be stored in the LoginConfig.txt file bundled with this module, the use of this file saves passing the PIN and user ID data with each call to bankValUK. For example a call to validate a UK bank account passing the user ID and PIN as parameters and printing the reply to console should follow this form:



 use Finance::BankVal::UK qw(&bankValUK);

 my $ans = bankValUK('XML','01-02-03','12345678','xmpl123','12345');

 print $ans;

=====================OR for Object Orientation=======================

 use Finance::BankVal::UK

 my $bvObj = Finance::BankVal::UK->new();
 my $ans = $bvObj->bankValUK('XML','01-02-03','12345678','xmpl123','12345');

 print $ans;


valid parameter lists are:-

bankValUK('$format','$sortcode','$account no.','$userID','$PIN');


bankValUK('$format','$sortcode','$account no.');


n.b. the last two parameter lists require that the user ID and PIN are stored in the LoginConfig.txt file bundled with this module.


None by default. &bankValUK is exported on request i.e. "use Finance::BankVal::UK qw(&bankValUK);"


This module requires these other modules and libraries:

use LWP::UserAgent; use XML::Simple; use JSON;

Crypt::SSLeay is also required as it is a dependency of LWP::UserAgent.

Crypt::SSLeay is typically bundled with windows Perl ports, however on *nix you may need to install it by:

sudo aptitude install libssl-dev (might not be neccessary and can be removed after install) sudo cpan -i Crypt::SSLeay
