Guide to cPanel API 2

Warning:

The cPanel API 2 system is deprecated. We strongly recommend that you use UAPI instead of cPanel API 2.


Overview

cPanel API 2 accesses cPanel account information and modifies settings.

Important:

When you enable a non-Standard Node server profile, the system disables API calls associated with that profile's disabled roles.


Notes:
  • If the desired function is available, we recommend that you use our newer UAPI functions.
  • You cannot call this API's functions via another API's call methods. For more information, read the API method distinctions section below.

Basic usage

WHM API

https://hostname.example.com:2087/cpsess##########/json-api/cpanel?cpanel_jsonapi_user=user&cpanel_jsonapi_apiversion=2&cpanel_jsonapi_module=Module&cpanel_jsonapi_func=function&parameter="value"

Template Toolkit

Note:

Currently, individual function documentation does not include Template Toolkit examples.


[%-
USE Api2;
SET myvariable = execute(
     'Module', 'function',
    {
        'parameter'      => 'value',
        'parameter'      => 'value',
        'parameter'      => 'value',
    }
);
%]
Note:

For more information, read our Guide to Template Toolkit documentation.


LiveAPI PHP Class

$cpanel = new CPANEL(); // Connect to cPanel - only do this once.

// Call the function.
$my_variable = $cpanel->api2(
    'Module', 'function',
    array(
        'parameter'      => 'value',
        'parameter'      => 'value',
        'parameter'      => 'value',
    )
 );
Note:

For more information, read our Guide to LiveAPI System documentation.


LiveAPI Perl Module

my $cpliveapi = Cpanel::LiveAPI->new(); # Connect to cPanel - only do this once.

# Call the function.
my $my_variable = $cpliveapi->api2(
   'Module', 'function',
   {
       'parameter'      => 'value',
       'parameter'      => 'value',
       'parameter'      => 'value',
   }
);
Note:

For more information, read our Guide to LiveAPI System documentation.


cPanel Tag System (deprecated)

Warning:
  • cPanel tags are deprecated . We strongly recommend that you only use the LiveAPI system to call the cPanel APIs. Examples are only present in order to help developers move from the old cPanel tag system to our LiveAPI.
  • cPanel API 2 calls that use cPanel tags vary in code syntax and in their output.
  • For more information, read our Deprecated cPanel Tag Usage documentation. 

<?cp Module::function (
     template,
     returns,
     returns
     )
          parameter="value",
          parameter="value",
          parameter="value",
?>

For more information, read our Use WHM API to Call cPanel API and UAPI documentation.


Warning:

Unless you call this API via the WHM API, you cannot call this API via WHM's ports (2086 or 2087).


This example uses the following variables:

Variable Description Example
Module The function's module. Email
function The cPanel API 2 function. addpop
parameter An input parameter's name. cPanel API 2 functions use named arguments. domain
value The input parameter's value. The term "Boolean" in our documentation refers to parameters that accept values of 1 or 0. cPanel & WHM's APIs do not support the literal values of true and false.
 example.com
template For cPanel tag function calls only, markup language that defines how the function's output displays.

For more information, read our Deprecated cPanel Tag Usage documentation.		 %[br /
returns For cPanel tag function calls only, a comma-separated list of return parameters, to limit the function's output.

For more information, read our Deprecated cPanel Tag Usage documentation.		 reason,result
Warning:

Do not attempt to use cPanel or WHM interface URLs to perform actions in custom code. You must call the appropriate API functions in order to perform the actions of cPanel & WHM's interfaces.

For example, do not pass values to .html pages, as in the following example:

http://example.com:2082/frontend/x3/mail/doaddpop.html/email=name&domain=user.com

While this unsupported method sometimes worked in previous versions of cPanel & WHM, we strongly discourage its use and do not guarantee that it will work in the future. Instead, the correct method to perform this action is to call the appropriate API function.


Command Line

cpapi2 --user=username --output=type Module function parameter=value parameter=value

cPanel API2 calls through the command line consist of the following basic parts:

command-line-api2

Part Description
Command This value is always cpapi2 for calls to cPanel API 2. If you run CloudLinux™, you must use the full path of the cpapi2 command: /usr/local/cpanel/bin/cpapi2.
Output Type The API output type that you wish to receive.
  • Use --output=json to return JSON-formatted output.
  • Use --output=jsonpretty to return indented JSON-formatted output.
  • Use --output=yaml to return YAML-formatted output.
This parameter defaults to --output=yaml.
Module The cPanel API 2 module name.
Function The cPanel API 2 function.
User The cPanel account-level username.
Input parameters and values The function's input parameters and their values.
  • You must URI-encode values.
  • Separate multiple parameter=value pairs with a space character.
  • Special characters within a key's value may cause an error. You must either escape any special characters within values or surround the value with appropriate quotes. For more information, read Wikipedia's Escape Characters article. For example, a bash shell command with a JSON-encoded value may appear similar to one of the following:
    • cpapi2 --user username Module function key=[\"sslinstall\",\"videotut\"]"
    • cpapi2 --user username Module function key='{"videotut","sslinstall"}'
The term "Boolean" in our documentation refers to parameters that accept values of 1 or 0. cPanel & WHM's APIs do not support the literal values of true and false.
Note:

For more information about this feature, run the following command:

cpapi2 --help

Custom Event Handlers and Standardized Hooks

You can use the Standardized Hook System to customize the events before and after a cPanel API call.

API method distinctions

WebPros International, LLC produces four current and two deprecated APIs, and they all include separate sets of functions. Make certain that the function and module that you call exist in the API version that your code uses.

Important:

API calls must use the correct port:

  • 2082 — Unsecure calls to cPanel's APIs.
  • 2083 — Secure calls to cPanel's APIs.
  • 2095 — Unsecure calls to cPanel's APIs via a Webmail session.
  • 2096 — Secure calls to cPanel's APIs via a Webmail session.
  • 2086 — Unsecure calls to WHM's APIs, or to cPanel's APIs via the WHM API.
  • 2087 — Secure calls to WHM's APIs, or to cPanel's APIs via the WHM API.

Otherwise-correct calls will return Permission denied or Function not found errors if they use an incorrect port number.


For more information, read our Guide to Testing Custom Code - cPanel API documentation.

Examples of calls to the desired API

WHM API 1 examples

Call through the WHM API

https://hostname.example.com:2087/cpsess##########/json-api/cpanel?cpanel_jsonapi_user=user&cpanel_jsonapi_apiversion=2&cpanel_jsonapi_module=Module&cpanel_jsonapi_func=function&parameter="value"
Note:

Browser-based calls to WHM API 1 must include the WHM API version (api.version=1). If you omit the version, the system calls WHM API 0, which may not contain the desired function, or may contain an older version of that function.


Command-line call

cpapi2 --user=username --output=type Module function parameter=value parameter=value
Note:

For more information, read our Guide to Testing Custom Code - WHM API Calls and Guide to WHM API 1 documentation.
