lib/API/INSEE/Sirene.pm  view on Meta::CPAN

Search all establishments which SIRET number is begining by the number given in parameter.

=head2 searchLegalUnitBySIREN

Search all legal units which SIREN number is begining by the number given in parameter.

=head2 setCredentials

You can set your credentials separately from the instantiation if you need to (but this must be done before any call to the search methods).

  $sirene->setCredentials('Y29uc3VtZXIta2V5OmNvbnN1bWVyLXNlY3JldA==');

=head2 setCurrentEndpoint

Used to specifie the reached API endpoint.

=head2 setDebugMode

Enables the debug mode. When enabled, all the requests built by the module are displayed instead of being sent.

  $sirene->setDebugMode(1);

=head2 setMaxResults

Used to override the B<< DEFAULT_MAX_RESULTS >> value to get more results, within the limit of B<< HARD_MAX_RESULTS >> value.

  $sirene->setMaxResults(30);

=head2 setProxy

You can define which proxy server must be used to send requests. The system's proxy settings are used by default.

  $sirene->setProxy('https://myproxy.com:1234');

=head2 setTimeout

Used to override the B<< DEFAULT_TIMEOUT >> value.

  $sirene->setTimeout(40);

=head1 PARAMETERS

All search methods take an optional C<< $desired_fields >> parameter that comes in three differents flavours:

  my $fields_that_interest_me = ['dateCreationUniteLegale', 'sigleUniteLegale'];
  my $response_json = $sirene->getLegalUnitBySIREN(123456789, $fields_that_interest_me);

  # or
  my $response_json = $sirene->getLegalUnitBySIREN(123456789, 'dateCreationUniteLegale');

  # or
  my $response_json = $sirene->getLegalUnitBySIREN(123456789, 'all');

When you don't specify any desired field, the module returns a selection of fields that are most likely to interest you. (see C<$useful_fields_legal_unit> and C<$useful_fields_establishment> in source code to find out which ones)

If you want all fields, you have to specify it explicitly by passing the value 'all' as parameter.

=head1 RETURN VALUES

Each method returns a list of two elements: a return code, which is 0 in case of success, or something else in case of failure; and the result of the request (some json or an error message). In case of problem when calling API (malformed request for ...

The module may launch a croak if the crendentials are not initialized or if the SIREN/SIRET numbers are not given in a correct format.

=head1 ALIAS

Some fields have more user-friendly aliases:

  my $useful_fields_aliases = {
    nicSiege                        => 'nicSiegeUniteLegale',
    nom                             => [ 'denominationUniteLegale', 'nomUniteLegale' ],
    dateCreation                    => 'dateCreationUniteLegale',
    sigle                           => 'sigleUniteLegale',
    categorieJuridique              => 'categorieJuridiqueUniteLegale',
    nomenclatureActivitePrincipale  => 'nomenclatureActivitePrincipaleUniteLegale',
    activitePrincipale              => 'activitePrincipaleUniteLegale',
    numvoie                         => 'numeroVoieEtablissement',
    typevoie                        => 'typeVoieEtablissement',
    nomvoie                         => 'libelleVoieEtablissement',
    codePostal                      => 'codePostalEtablissement',
    nomCommune                      => 'libelleCommuneEtablissement',
    adresseComplete                 => [
                                        'numeroVoieEtablissement',
                                        'typeVoieEtablissement', 'libelleVoieEtablissement',
                                        'codePostalEtablissement', 'libelleCommuneEtablissement'
                                    ],
  };

B<Usage:>

  my $response_json = $sirene->getLegalUnitBySIREN(123456789, 'nom');

is equivalent to

  my $response_json = $sirene->getLegalUnitBySIREN(123456789, 'denominationUniteLegale');
