NAME

cPanel::APIClient - cPanel APIs, à la TIMTOWTDI!

SYNOPSIS

Create a cPanel::APIClient::Service::cpanel object to call cPanel APIs:

my $cpanel = cPanel::APIClient->create(
    service => 'cpanel',
    transport => [ 'CLISync' ],
);

my $resp = $cpanel->call_uapi( 'Email', 'list_pops' );

my $pops_ar = $resp->get_data();

Create a cPanel::APIClient::Service::whm object to call WHM APIs:

my $whm = cPanel::APIClient->create(
    service => 'whm',
    transport => [ 'CLISync' ],
);

my $resp = $whm->call_api1( 'listaccts' );

my $accts_ar = $resp->get_data();

DESCRIPTION

cPanel & WHM exposes a number of ways to access its APIs: different transport mechanisms, different authentication schemes, etc. This library provides client logic with sufficient abstractions to accommodate most supported access mechanisms via a unified interface.

This library intends to supersede cPanel::PublicAPI as the preferred way to access cPanel & WHM’s APIs from Perl. It can also serve as a model for similar client libraries in other languages.

FEATURES

• Fully object-oriented.
• Can use blocking or non-blocking I/O. Non-blocking I/O implementation works with almost any modern Perl event loop interface.
• Uses minimal dependencies: no Moose &c.
• Extensively tested.
• Can run in pure Perl.

CHARACTER ENCODING

cPanel & WHM’s API is character-set-agnostic. All text that you give to this library should thus be encoded to binary, and all strings that you’ll receive back will be binary.

This means that if you character-decode your inputs—as perlunitut recommends—then you’ll need to encode your strings back to bytes before giving them to this module.

Use of UTF-8 encoding is strongly recommended!

FUNCTIONS

$client = cPanel::APIClient->create( %OPTS )

A factory function that creates a “client” object that your code can use to call the APIs.

%OPTS are:

• service - Required. The service that exposes the API(s) to call. This controls the class of the returned object. Recognized values are:

  • cpanel - Function will return a cPanel::APIClient::Service::cpanel instance.
  • whm - Function will return a cPanel::APIClient::Service::whm instance.

• transport - Required. An array reference that describes the transport mechanism to use. The first member of this array names the mechanism; remaining arguments are key-value pairs of attributes to give to the mechanism class’s constructor.

  Currently supported mechanisms are:

  • cPanel::APIClient::Transport::HTTPSync (HTTPSync) - Synchronous HTTP requests.
  • cPanel::APIClient::Transport::CLISync (CLISync) - Synchronous local requests via cPanel & WHM’s command-line API tools.
  • cPanel::APIClient::Transport::NetCurlPromiser (NetCurlPromiser) - Asynchronous HTTP requests via Net::Curl::Promiser, which can use any event loop interface. As of this writing it supports IO::Async, AnyEvent, and Mojolicious out-of-the-box.
  • cPanel::APIClient::Transport::MojoUserAgent (MojoUserAgent) - Asynchronous HTTP requests via Mojo::UserAgent (pure Perl).

  Which of the above to use will depend on your needs. If your application is local to the cPanel & WHM server you might find it easiest to use CLISync. For HTTP NetCurlPromiser offers the best flexibility and (probably) speed, whereas MojoUserAgent and HTTPSync can run in pure Perl (assuming you have Net::SSLeay).

  There currently is no documentation for how to create a 3rd-party transport mechanism (e.g., if you want to use a different HTTP library). Submissions via pull request will be evaluated on a case-by-case basis.

• credentials - Some transports require this; others don’t. The recognized schemes are:

  • username & api_token - Authenticate with an API token
  • username & password - Authenticate with a password
  • username, password, & tfa_token - Authenticate with a password and two-factor authentication (2FA) token.
  • username only - Implicit authentication, only usable for local transports.

Depending on the service given, this function returns an instance of either cPanel::APIClient::Service::cpanel or cPanel::APIClient::Service::whm.
