NAME

Business::Monzo - Perl library for interacting with the Monzo API (https://api.monzo.com)

VERSION

0.08

DESCRIPTION

Business::Monzo is a library for easy interface to the Monzo banking API, it implements all of the functionality currently found in the service's API documentation: https://monzo.com/docs

You should refer to the official Monzo API documentation in conjunction with this perldoc, as the official API documentation explains in more depth some of the functionality including required / optional parameters for certain methods.

Please note this library is very much a work in progress, as is the Monzo API. Also note the Monzo were previously called Mondo, so if you see any references to Mondo they are either typos or historical references that have not yet been updated to reflect the changes.

All objects within the Business::Monzo namespace are immutable. Calls to methods will, for the most part, return new instances of objects.

SYNOPSIS

my $monzo = Business::Monzo->new(
    token   => $token, # REQUIRED
    api_url => $url,   # optional
);

# transaction related information
my @transactions = $monzo->transactions( account_id => $account_id );

my $Transaction  = $monzo->transaction( id => 1 );

$Transaction->annotate(
    foo => 'bar',
    baz => 'boz,
);

my $annotations = $Transaction->annotations;

# account related information
my @accounts = $monzo->accounts;

foreach my $Account ( @accounts ) {

    my @transactions = $Account->transactions;

    $Account->add_feed_item(
        params => {
            title     => 'My Feed Item',
            image_url => 'http://...',
        }
    );

    # balance information
    my $Balance = $Account->balance;

    # webhooks
    my @webhooks = $Account->webhooks;

    my $Webhook = $Account->register_webhook(
        callback_url => 'http://www.foo.com',
    );

    $Webhook->delete
}

# attachments
my $Attachment = $monzo->upload_attachment(
    file_name => 'foo.png',
    file_type => 'image/png',
);

$Attachment->register(
    external_id => 'my_id'
);

$Attachment->deregister;

ERROR HANDLING

Any problems or errors will result in a Business::Monzo::Exception object being thrown, so you should wrap any calls to the library in the appropriate error catching code (ideally a module from CPAN):

try {
    ...
}
catch ( Business::Monzo::Exception $e ) {
    # error specific to Business::Monzo
    ...
    say $e->message;  # error message
    say $e->code;     # HTTP status code
    say $e->response; # HTTP status message

    # ->request may not always be present
    say $e->request->{path}    if $e->request
    say $e->request->{params}  if $e->request
    say $e->request->{headers} if $e->request
    say $e->request->{content} if $e->request
}
catch ( $e ) {
    # some other failure?
    ...
}

You can view some useful debugging information by setting the MONZO_DEBUG env varible, this will show the calls to the Monzo endpoints as well as a stack trace in the event of exceptions:

$ENV{MONZO_DEBUG} = 1;
