.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
cPanel::PublicAPI is a supported interface for interacting with cPanel's APIs over \s-1HTTP.\s0
This allows you to query either \s-1WHM\s0 or cPanel accounts from a perl interface. The purpose
of this module is to provide an easy-to-use interface into cPanel's various APIs without
requiring much knowledge of how they work.
.SS "Object Construction"
.IX Subsection "Object Construction"
A cPanel::PublicAPI object is constructed with the \fInew()\fR method.
.PP
.Vb 1
\& my $publicapi = cPanel::PublicAPI\->new();
.Ve
.PP
When passed no parameters this create the object using the accesshash in ~/.accesshash. If no .accesshash file exists, it will attempt to use the \s-1REMOTE_PASS\s0 environment variable, if that is not defined, object creation will error out.
.PP
\fI\fInew()\fI parameters\fR
.IX Subsection "new() parameters"
.PP
options for \fInew()\fR are specified as a hash reference, the following parameters are supported:
.IP "\(bu" 4
user \- The username for authentication.
.IP "\(bu" 4
pass \- The password to use for authentication.
.IP "\(bu" 4
accesshash \- The accesshash to use for authentication.
.IP "\(bu" 4
timeout \- The length of time (in seconds) before an http request should time out. Default to 300.
.IP "\(bu" 4
ip \- The \s-1IP\s0 to be queried. defaults to 127.0.0.1, if host is defined it will take precedence over the 'ip' parameter.
.IP "\(bu" 4
host \- The hostname to be queried. This will take precedence over the 'ip' parameter.
.IP "\(bu" 4
usessl \- 1 or 0, Indicates whether communication should be performed over \s-1SSL\s0 or not (default to 1).
.IP "\(bu" 4
error_log \- Path to where you want debug and error logging information well be written. If this is not defined or the module is unable to open the path in question, it will default to \s-1STDERR.\s0
.IP "\(bu" 4
debug \- Enables debug logging, which will place considerably more information into the error_log.
.PP
\fINotes about authentication\fR
.IX Subsection "Notes about authentication"
.PP
There are two sets of credentials that can be used to authenticate to \s-1WHM.\s0
.PP
First we have the basic user/password combinations:
.PP
.Vb 2
\& use Cpanel::PublicAPI;
\& my $pubapi = Cpanel::PublicAPI\->new( \*(Aquser\*(Aq => \*(Aqfoo\*(Aq, \*(Aqpassword\*(Aq => \*(Aqbar\*(Aq );
.Ve
.PP
The other type of authentication is accesshash authentication. To configure accesshashes visit a\*^XXSetup remote access keya\*^XX
in \s-1WHM\s0 which will generate an accesshash for your server if one does not already exist. It will store the generated accesshash
in /root/.accesshash. To use an accesshash with this module you can do something like the following:
.PP
.Vb 2
\& use Cpanel::PublicAPI;
\& my $pubapi = Cpanel::PublicAPI\->new( \*(Aquser\*(Aq => \*(Aqfoo\*(Aq, \*(Aqaccesshash\*(Aq => $string_containing_access_hash );
.Ve
.PP
It should be noted that the access hash can contain newlines in it, Newlines will be stripped by the object when
it attempts to perform a query.
.PP
\fIDependencies\fR
.IX Subsection "Dependencies"
.PP
This module will fall back on different modules if one fails to load. This allows for compatibility with cPanel & \s-1WHM\s0's internal perl parser and maintain compatibility with a standard perl implementation. The order that it will fall back on serialization modules is:
.IP "\(bu" 4
JSON::Syck
.IP "\(bu" 4
\&\s-1JSON\s0
.IP "\(bu" 4
\&\s-1JSON::XS\s0
.IP "\(bu" 4
\&\s-1JSON::PP\s0
.PP
If you installed this module via \s-1CPAN,\s0 this should never be an issue. If you are wishing to use this
module on a system where you do not have access to compiled modules, \s-1JSON::PP\s0 is the recommended serializer.
.SH "Important Methods"
.IX Header "Important Methods"
.SS "Querying the xml-api \- \fIwhm_api()\fP"
.IX Subsection "Querying the xml-api - whm_api()"
The XML-API is \s-1WHM\s0's \s-1API\s0 used for administrative functions is handled via the \fIwhm_api()\fR method.
.PP
The syntax for whmapi is:
.PP
.Vb 1
\& $cp\->whm_api($call [, \e%formdata, $format ] );
.Ve
.PP
The meaning of these parameters is:
.IP "\(bu" 4
\&\f(CW$call\fR \- The XML-API call you wish to query
.IP "\(bu" 4
\&\f(CW$formdata\fR \- The parameters for the XML-API call in question, f.ex. for suspendacct, here you would pass in a hashref containing a\*^XXusera\*^XX and a\*^XXreasona\*^XX. If there are no parameters, this can be undef or a blank hash.
.IP "\(bu" 4
\&\f(CW$format\fR \- The requested response format. The valid values here are a\*^XXxmla\*^XX, a\*^XXjsona\*^XX or a\*^XXrefa\*^XX (perl hash reference). This will default to returning a perl hash reference when the value is undef.
.PP
For more information on what calls are available and how they can be referenced, please see the xml-api documentation at <http://docs.cpanel.net/twiki/bin/view/SoftwareDevelopmentKit/XmlApi>.
.SS "Querying cPanel's APIs"
.IX Subsection "Querying cPanel's APIs"
cPanel supports two APIs, designated \*(L"\s-1API1\*(R"\s0 and \*(L"\s-1API2\*(R".\s0
.PP
cPanel \s-1API\s0 calls are seperate into Modules, these module names relate to modules within the Cpanel namespace on a cPanel server. Each module defines a set of functions that are from either \s-1API1\s0 or \s-1API2 \s0(or both).
.PP
There are two distinct differences between \s-1API1\s0 and \s-1API2:\s0
.IP "\(bu" 4
\&\s-1API1\s0 Takes in ordered parameters and returns strings
.IP "\(bu" 4
\&\s-1API2\s0 uses named parameters and returns hashes or arrays of hashes
.PP
Within the context of the public api, calling a function from \s-1API1\s0 or \s-1API2\s0 will always return a hash, but the specific data returned from the \s-1API\s0 call will be contained within the 'data' key of the response.
.PP
For more information on the differences between \s-1API1\s0 and \s-1API2\s0 please see the documentation: <http://docs.cpanel.net/twiki/bin/view/SoftwareDevelopmentKit/ApiIntroduction>
.PP
For information on calling \s-1API1\s0 and \s-1API2\s0 direct via \s-1HTTP,\s0 please see: <http://docs.cpanel.net/twiki/bin/view/SoftwareDevelopmentKit/CallingAPIFunctions>
.PP
\fI\fIcpanel_api1_request()\fI\fR
.IX Subsection "cpanel_api1_request()"
.PP
\&\f(CW\*(C`cpanel_api1_request()\*(C'\fR is used to query cPanel's \s-1API1,\s0 the function used for querying \s-1API1\s0 has the following syntax:
.PP
.Vb 1
\& $cp\->cpanel_api1_request($service, \e%cfg [, \e@params, $format ] );
.Ve
.IP "\(bu" 4
\&\f(CW$service\fR \- The service that you wish to query. This can be 'cpanel' 'whostmgr', or 'webmail'. It is important to note that what services you are able to query depends on the user you are authenticated as. Only a user with reseller or root access can use the whostmgr service. If you are authenticated as root, you will not be able to query the 'cpanel' service. When the service is set to 'whostmgr' a 'user' must be set in the \f(CW$cfg\fR hash.
.IP "\(bu" 4
\&\f(CW$cfg\fR \- A hash reference describing the call you wish to make. Required parameters are 'module' and 'func', which correspond to the module and function of the \s-1API\s0 call you wish to query. If you are querying the \*(L"whostmgr\*(R" service, you will need to specify 'user' as well.
.IP "\(bu" 4
\&\f(CW$params\fR \- An array reference containing the parameters you wish to pass to the \s-1API\s0 call.
.IP "\(bu" 4
\&\f(CW$format\fR \- The format for the xml-api to respond in. The valid values here are a\*^XXxmla\*^XX, a\*^XXjsona\*^XX or a\*^XXrefa\*^XX (perl hash reference). This will default to returning a perl hash reference.
.PP

It is important to note that what services you are able to query depends on the user you are authenticated as. A user that does not have reseller or root access will not be able to use the whostmgr service. If you are authenticated as root, you will not be able to query the 'cpanel' service. When the service is set to 'whostmgr' a 'user' must be set in the \f(CW$cfg\fR hash.

.PP
To see what modules and functions are available for making \s-1API2\s0 calls, please see: <http://docs.cpanel.net/twiki/bin/view/ApiDocs/Api2/WebHome>
.SS "\fIapi_request()\fP \- Making direct \s-1URL\s0 requests to cPanel & \s-1WHM.\s0"
.IX Subsection "api_request() - Making direct URL requests to cPanel & WHM."
There are some situations where you will need to query cPanel and \s-1WHM\s0 URLs directly. This should \s-1ONLY\s0 be done when there is not an \s-1API\s0 call available for the function you wish to query.
.PP
The function used for querying URLs directly is \fIapi_request()\fR. It will always return a string rather than converting the response into a hash reference. It uses the following syntax:
.PP
.Vb 1
\& $cp\->api_request( $service, $uri, $method, \e%formdata, $headers)
.Ve
.IP "\(bu" 4
\&\f(CW$service\fR \- The service that you wish to query. This can be 'cpanel' 'whostmgr', or 'webmail', when passed an numerical value, PublicAPI will query that port directly.
.IP "\(bu" 4
\&\f(CW$uri\fR \- The \s-1URL\s0 you wish to query, e.g. '/xml\-api/cpanel'
.IP "\(bu" 4
\&\f(CW$method\fR \- '\s-1GET\s0' or '\s-1POST\s0'
.IP "\(bu" 4
\&\f(CW$formdata\fR \- The data to be passed to the \s-1URL\s0
.IP "\(bu" 4
