Business::PayPal::API - PayPal API
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
use Business::PayPal::API qw( ExpressCheckout GetTransactionDetails );
|
|
|
|
## certificate authentication
|
|
my $pp = new Business::PayPal::API
|
|
( Username => 'my_api1.domain.tld',
|
|
Password => 'this_is_my_password',
|
|
PKCS12File => '/path/to/cert.pkcs12',
|
|
PKCS12Password => '(pkcs12 password)',
|
|
sandbox => 1 );
|
|
|
|
## PEM cert authentication
|
|
my $pp = new Business::PayPal::API
|
|
( Username => 'my_api1.domain.tld',
|
|
Password => 'this_is_my_password',
|
|
CertFile => '/path/to/cert.pem',
|
|
KeyFile => '/path/to/cert.pem',
|
|
sandbox => 1 );
|
|
|
|
## 3-token (Signature) authentication
|
|
my $pp = new Business::PayPal::API
|
|
( Username => 'my_api1.domain.tld',
|
|
Password => 'Xdkis9k3jDFk39fj29sD9', ## supplied by PayPal
|
|
Signature => 'f7d03YCpEjIF3s9Dk23F2V1C1vbYYR3ALqc7jm0UrCcYm-3ksdiDwjfSeii', ## ditto
|
|
sandbox => 1 );
|
|
|
|
my %response = $pp->SetExpressCheckout( ... );
|
|
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
B<Business::PayPal::API> supports both certificate authentication and
|
|
the new 3-token "Signature" authentication.
|
|
|
|
It also support PayPal's development I<sandbox> for testing. See the
|
|
B<sandbox> parameter to B<new()> below for details.
|
|
|
|
B<Business::PayPal::API> can import other B<API> derived classes:
|
|
|
|
use Business::PayPal::API qw( RefundTransaction );
|
|
|
|
This allows for much more concise and intuitive usage. For example,
|
|
these two statements are equivalent:
|
|
|
|
use Business::PayPal::API::RefundTransaction;
|
|
my $pp = new Business::PayPal::API::RefundTransaction( ... );
|
|
$pp->RefundTransaction( ... );
|
|
|
|
and more concisely:
|
|
|
|
use Business::PayPal::API qw( RefundTransaction );
|
|
my $pp = new Business::PayPal::API( ... );
|
|
$pp->RefundTransaction( ... );
|
|
|
|
The advantage of this becomes clear when you need to use multiple API
|
|
calls in your program; this allows you to use the same object to
|
|
invoke the various methods, instead of creating a new object for each
|
|
subclass. Here is an example of a B<API> object used to invoke various
|
|
PayPal APIs with the same object:
|
|
|
|
use Business::PayPal::API qw( GetTransactionDetails
|
|
TransactionSearch
|
|
RefundTransaction );
|
|
my $pp = new Business::PayPal::API( ... );
|
|
my $records = $pp->TransactionSearch( ... );
|
|
|
|
my %details = $pp->GetTransactionDetails( ... );
|
|
|
|
my %resp = $pp->RefundTransaction( ... );
|
|
|
|
However, you may certainly use just the subclass if that's all you
|
|
need. Every subclass should work as its own self-contained API.
|
|
|
|
For details on B<Business::PayPal::API::*> subclasses, see each
|
|
subclass's individual documentation.
|
|
|
|
=head2 new
|
|
|
|
Creates a new B<Business::PayPal::API> object.
|
|
|
|
A note about certificate authentication: PayPal (and this module)
|
|
support either PKCS#12 certificate authentication or PEM certificate
|
|
authentication. See options below.
|
|
|
|
=over 4
|
|
|
|
=item B<Username>
|
|
|
|
Required. This is the PayPal API username, usually in the form of
|
|
'my_api1.mydomain.tld'. You can find or create your API credentials by
|
|
logging into PayPal (if you want to do testing, as you should, you
|
|
should also create a developer sandbox account) and going to:
|
|
|
|
My Account -> Profile -> API Access -> Request API Credentials
|
|
|
|
Please see the I<PayPal API Reference> and I<PayPal Sandbox User
|
|
Guide> for details on creating a PayPal business account and sandbox
|
|
account for testing.
|
|
|
|
=item B<Password>
|
|
|
|
Required. If you use certificate authentication, this is the PayPal
|
|
API password created when you setup your certificate. If you use
|
|
3-token (Signature) authentication, this is the password PayPal
|
|
assigned you, along with the "API User Name" and "Signature Hash".
|
|
|
|
=item B<Subject>
|
|
|
|
Optional. This is used by PayPal to authenticate 3rd party billers
|
|
using your account. See the documents in L<SEE ALSO>.
|
|
|
|
=item B<Signature>
|
|
|
|
Required for 3-token (Signature) authentication. This is the
|
|
"Signature Hash" you received when you did "Request API Credentials"
|
|
in your PayPal Business Account.
|
|
|
|
=item B<PKCS12File>
|
|
|
|
Required for PKCS#12 certificate authentication, unless the
|
|
B<HTTPS_PKCS12_FILE> environment variable is already set.
|
|
|
|
This contains the path to your private key for PayPal
|
|
authentication. It is used to set the B<HTTPS_PKCS12_FILE> environment
|
|
variable. You may set this environment variable yourself and leave
|
|
this field blank.
|
|
|
|
=item B<PKCS12Password>
|
|
|
|
Required for PKCS#12 certificate authentication, unless the
|
|
B<HTTPS_PKCS12_PASSWORD> environment variable is already set.
|
|
|
|
This contains the PKCS#12 password for the key specified in
|
|
B<PKCS12File>. It is used to set the B<HTTPS_PKCS12_PASSWORD>
|
|
environment variable. You may set this environment variable yourself
|
|
and leave this field blank.
|
|
|
|
=item B<CertFile>
|
|
|
|
Required for PEM certificate authentication, unless the
|
|
HTTPS_CERT_FILE environment variable is already set.
|
|
|
|
This contains the path to your PEM format certificate given to you
|
|
from PayPal (and accessible in the same location that your Username
|
|
and Password and/or Signature Hash are found) and is used to set the
|
|
B<HTTPS_CERT_FILE> environment variable. You may set this environment
|
|
variable yourself and leave this field blank.
|
|
|
|
You may combine both certificate and private key into one file and set
|
|
B<CertFile> and B<KeyFile> to the same path.
|
|
|
|
=item B<KeyFile>
|
|
|
|
Required for PEM certificate authentication, unless the HTTPS_KEY_FILE
|
|
environment variable is already set.
|
|
|
|
This contains the path to your PEM format private key given to you
|
|
from PayPal (and accessible in the same location that your Username
|
|
and Password and/or Signature Hash are found) and is used to set the
|
|
B<HTTPS_KEY_FILE> environment variable. You may set this environment
|
|
variable yourself and leave this field blank.
|
|
|
|
You may combine both certificate and private key into one file and set
|
|
B<CertFile> and B<KeyFile> to the same path.
|
|
|
|
=item B<sandbox>
|
|
|
|
Required. If set to true (default), B<Business::PayPal::API> will
|
|
connect to PayPal's development sandbox, instead of PayPal's live
|
|
site. *You must explicitly set this to false (0) to access PayPal's
|
|
live site*.
|
|
|
|
If you use PayPal's development sandbox for testing, you must have
|
|
already signed up as a PayPal developer and created a Business sandbox
|
|
account and a Buyer sandbox account (and make sure both of them have
|
|
B<Verified> status in the sandbox).
|
|
|
|
When testing with the sandbox, you will use different usernames,
|
|
passwords, and certificates (if using certificate authentication) than
|
|
you will when accessing PayPal's live site. Please see the PayPal
|
|
documentation for details. See L<SEE ALSO> for references.

=head1 ERROR HANDLING
|
|
|
|
Every API call should return an B<Ack> response, whether I<Success>,
|
|
I<Failure>, or otherwise (depending on the API call). If it returns
|
|
any non-success value, you can find an I<Errors> entry in your return
|
|
hash, whose value is a listref of hashrefs:
|
|
|
|
[ { ErrorCode => 10002,
|
|
LongMessage => "Invalid security header" },
|
|
|
|
{ ErrorCode => 10030,
|
|
LongMessage => "Some other error" }, ]
|
|
|
|
You can retrieve these errors like this:
|
|
|
|
%response = $pp->doSomeAPICall();
|
|
if( $response{Ack} ne 'Success' ) {
|
|
for my $err ( @{$response{Errors}} ) {
|
|
warn "Error: " . $err->{LongMessage} . "\n";
|
|
}
|
|
}
|
|
|
|
=head1 TESTING
|
|
|
|
Testing the B<Business::PayPal::API::*> modules requires that you
|
|
create a file containing your PayPal Developer Sandbox authentication
|
|
credentials (e.g., API certificate authentication or 3-Token
|
|
authentication signature, etc.) and setting the B<WPP_TEST>
|
|
environment variable to point to this file.
|
|
|
|
The format for this file is as follows:
|
|
|
|
Username = your_api.username.com
|
|
Password = your_api_password
|
|
|
|
and then ONE of the following options:
|
|
|
|
a) supply 3-token authentication signature
|
|
|
|
Signature = xxxxxxxxxxxxxxxxxxxxxxxx
|
|
|
|
b) supply PEM certificate credentials
|
|
|
|
CertFile = /path/to/cert_key_pem.txt
|
|
KeyFile = /path/to/cert_key_pem.txt
|
|
|
|
c) supply PKCS#12 certificate credentials
|
|
|
|
PKCS12File = /path/to/cert.p12
|
|
PKCS12Password = pkcs12_password
|
|
|
|
You may also set the appropriate HTTPS_* environment variables for b)
|
|
and c) above (e.g., HTTPS_CERT_FILE, HTTPS_KEY_FILE,
|
|
HTTPS_PKCS12_File, HTTPS_PKCS12_PASSWORD) in lieu of putting this
|
|
information in a file.
|
|
|
|
Then use "WPP_TEST=my_auth.txt make test" (for Bourne shell derivates) or
|
|
"setenv WPP_TEST my_auth.txt && make test" (for C-shell derivates).
|
|
|
|
See 'auth.sample.*' files in this package for an example of the file
|
|
format. Variables are case-*sensitive*.
|
|
|
|
Any of the following variables are recognized:
|
|
|
|
Username Password Signature Subject
|
|
CertFile KeyFile PKCS12File PKCS12Password
|
|
BuyerEmail
|
|
|
|
Note: PayPal authentication may I<fail> if you set the certificate

environment variables and attempt to connect using 3-token

=head2 PayPal Authentication Errors
|
|
|
|
If you are experiencing PayPal authentication errors (e.g., "Security
|
|
header is not valid", "SSL negotiation failed", etc.), you should make
|
|
sure:
|
|
|
|
* your username and password match those found in your PayPal
|
|
Business account sandbox (this is not the same as your regular
|
|
account.
|
|
|
|
* you're not trying to use your live username and password for
|
|
sandbox testing and vice versa.
|
|
|
|
* if the sandbox works but "live" does not, make sure you've turned
|
|
off the 'sandbox' parameter correctly. Otherwise you'll be
|
|
passing your PayPal sandbox credentials to PayPal's live site
|
|
(which won't work).
|
|
|
|
* if you use certificate authentication, your certificate must be
|
|
the correct one (live or sandbox) depending on what you're doing.
|
|
|
|
* if you use 3-Token authentication (i.e., Signature), you don't
|
|
have any B<PKCS12*> parameters or B<CertFile> or B<KeyFile>
|
|
parameters in your constructor AND that none of the corresponding
|
|
B<HTTPS_*> environment variables are set. PayPal prefers
|
|
certificate authentication since it occurs at connection time; if
|
|
it fails, it will not try Signature authentication.
|
|
|
|
Try clearing your environment:
|
|
|
|
## delete all HTTPS, SSL env
|
|
delete $ENV{$_} for grep { /^(HTTPS|SSL)/ } keys %ENV;
|
|
|
|
## now put our own HTTPS env back in
|
|
$ENV{HTTPS_CERT_FILE} = '/var/path/to/cert.pem';
|
|
|
|
## create our paypal object
|
|
my $pp = new Business::PayPal::API...
|
|
|
|
* if you have already loaded Net::SSLeay (or IO::Socket::SSL), then
|
|
Net::HTTPS will prefer to use IO::Socket::SSL. I don't know how
|
|
to get SOAP::Lite to work with IO::Socket::SSL (e.g.,
|
|
Crypt::SSLeay uses HTTPS_* environment variables), so until then,
|
|
you can use this hack:
|
|
|
|
local $IO::Socket::SSL::VERSION = undef;
|
|
|
|
$pp->DoExpressCheckoutPayment(...);
|
|
|
|
This will tell Net::HTTPS to ignore the fact that IO::Socket::SSL
|
|
is already loaded for this scope and import Net::SSL (part of the
|
|
Crypt::SSLeay package) for its 'configure()' method.
|
|
|
|
* if you receive a message like "500 Can't connect to
|
|
api.sandbox.paypal.com:443 (Illegal seek)", you'll need to make
|
|
sure you have Crypt::SSLeay installed. It seems that other crypto
|
|
modules don't do the certificate authentication quite as well,
|
|
and LWP needs this to negotiate the SSL connection with PayPal.
|
|
|
|
See the DEBUGGING section below for further hints.

|
=head2 PayPal Munging URLs
|
|
|
|
PayPal seems to be munging my URLs when it returns.
|
|
|
|
SOAP::Lite follows the XML specification carefully, and encodes '&'
|
|
and '<' characters before applying them to the SOAP document. PayPal
|
|
does not properly URL-decode HTML entities '&' and '<' on the
|
|
way back, so if you have an ampersand in your ReturnURL (for example),
|
|
your customers will be redirected here:
|
|
|
|
http://domain.tld/prog?arg1=foo&arg2=bar
|
|
|
|
instead of here:
|
|
|
|
http://domain.tld/prog?arg1=foo&arg2=bar
|
|
|
|
Solution:
|
|
|
|
Use CDATA tags to wrap your request:
|
|
|
|
ReturnURL => '<![CDATA[http://domain.tld/prog?arg1=foo&arg2=bar]]>'
|
|
|
|
You may also use semicolons instead of ampersands to separate your URL
|
|
arguments:
|
|
|
|
ReturnURL => 'http://domain.tld/prog?arg1=foo;arg2=bar'
|
|

|
=head1 DEBUGGING
|
|
|
|
You can see the raw SOAP XML sent and received by
|
|
B<Business::PayPal::API> by setting it's B<$Debug> variable:
|
|
|
|
$Business::PayPal::API::Debug = 1;
|
|
$pp->SetExpressCheckout( %args );
|
|
|
|
this will print the XML being sent, and dump a Perl data structure of
|
|
the SOM received on STDERR (so check your error_log if running inside
|
|
a web server).
|
|
|
|
If anyone knows how to turn a SOAP::SOM object into XML without
|
|
setting B<outputxml()>, let me know.
|
|
|
|
=head1 DEVELOPMENT
|
|
|
|
If you are a developer wanting to extend B<Business::PayPal::API> for
|
|
other PayPal API calls, you can review any of the included modules
|
|
(e.g., F<RefundTransaction.pm> or F<ExpressCheckout.pm>) for examples
|
|
on how to do this until I have more time to write a more complete
|
|
document.
|
|
|
|
But in a nutshell:
|
|
|
|
package Business::PayPal::API::SomeAPI;
|
|
|
|
use 5.008001;
|
|
use strict;
|
|
use warnings;
|
|
|
|
use SOAP::Lite 0.67;
|
|
use Business::PayPal::API ();
|
|
|
|
our @ISA = qw(Business::PayPal::API);
|
|
our @EXPORT_OK = qw( SomeAPIMethod );
|
|
|
|
sub SomeAPIMethod {
|
|
...
|
|
}
|
|
|
|
Notice the B<@EXPORT_OK> variable. This is I<not> used by B<Exporter>
|
|
(we don't load Exporter at all): it is a special variable used by
|
|
B<Business::PayPal::API> to know which methods to import when
|
|
B<Business::PayPal::API> is run like this:
|
|
|
|
use Business::PayPal::API qw( SomeAPI );
|
|
|
|
That is, B<Business::PayPal::API> will import any subroutine into its
|
|
own namespace from the B<@EXPORT_OK> array. Now it can be used like this:
|
|
|
|
use Business::PayPal::API qw( SomeAPI );
|
|
my $pp = new Business::PayPal::API( ... );
|
|
$pp->SomeAPIMethod( ... );
|
|
|
|
Of course, we also do a 'use Business::PayPal::API' in the module so
|
|
that it can be used as a standalone module, if necessary:
|
|
|
|
use Business::PayPal::API::SomeAPI;
|
|
my $pp = new Business::PayPal::API::SomeAPI( ... ); ## same args as superclass
|
|
$pp->SomeAPIMethod( ... );
|
|
|
|
Adding the B<@EXPORT_OK> array in your module allows your module to be
|
|
used in the most convenient way for the given circumstances.
|
|
|
|
=head1 EXAMPLES
|
|
|
|
Andy Spiegl <paypalcheckout.Spiegl@kascada.com> has kindly donated
|
|
some example code (in German) for the ExpressCheckout API which may be
|
|
found in the F<eg> directory of this archive. Additional code examples
|
|
for other APIs may be found in the F<t> test directory.
|
|
|
|
=head1 EXPORT
|
|
|
|
None by default.
|
|
|
|
=head1 CAVEATS
|
|
|
|
Because I haven't figured out how to make SOAP::Lite read the WSDL
|
|
definitions directly and simply implement those (help, anyone?), I
|
|
have essentially recreated all of those WSDL structures internally in
|
|
this module.
|
|
|
|
(Note - 6 Oct 2006: SOAP::Lite's WSDL support is moving ahead, but
|
|
slowly. The methods used by this API are considered "best practice"
|
|
and are safe to use).
|
|
|
|
As with all web services, if PayPal stop supporting their API
|
|
endpoint, this module *may stop working*. You can help me keep this
|
|
module up-to-date if you notice such an event occuring.
|
|
|
|
Also, I didn't implement a big fat class hierarchy to make this module
|
|
"academically" correct. You'll notice that I fudged colliding
|
|
parameter names in B<DoExpressCheckoutPayment> and similar fudging may
|
|
be found in B<GetTransactionDetails>. The good news is that this was
|
|
written quickly, works, and is dead-simple to use. The bad news is
|
|
that this sort of collision might occur again as more and more data is
|
|
sent in the API (call it 'eBay API bloat'). I'm willing to take the
|
|
risk this will be rare (PayPal--please make it rare!).
