NAME

       Net::Duo - API for Duo multifactor authentication service

SYNOPSIS

           my $duo = Net::Duo->new({ key_file => '/path/to/keys.json' });
           my $reply = $duo->call_json('GET', '/auth/v2/check');

REQUIREMENTS

       Perl 5.14 or later and the modules HTTP::Request and HTTP::Response (part of
       HTTP::Message), JSON, LWP (also known as libwww-perl), Perl6::Slurp, and URI::Escape (part
       of URI), all of which are available from CPAN.

DESCRIPTION

       Net::Duo provides an object-oriented Perl interface for generic calls to one of the the
       Duo Security REST APIs.  This module is intended primarily for use as a base class for
       more specialized Perl modules implementing the specific Duo APIs, but it can also be used
       directly to make generic API calls.

       On failure, all methods throw a Net::Duo::Exception object.  This can be interpolated into
       a string for a simple error message, or inspected with method calls for more details.
       This is also true of all methods in all objects in the Net::Duo namespace.

CLASS METHODS

       new(ARGS)
           Create a new Net::Duo object.  This should be used for all subsequent API calls.  ARGS
           should be a hash reference with one or more of the following keys:

           api_hostname
               The API hostname returned by Duo when the API integration was created.

               This key is required if "key_file" is not set.

           integration_key
               The integration key returned by Duo when the API integration was created.  This is
               effectively the public "username" for this integration.

               This key is required if "key_file" is not set.

           key_file
               The path to a file in JSON format that contains the key and hostname data for a
               Duo integration.  This file should contain one JSON object with keys
               "integration_key", "secret_key", and "api_hostname".  These are the three data
               values that are returned when one creates a new Duo API integration.

               Be aware that the "secret_key" value in this file is security-sensitive
               information equivalent to a password.  Anyone in possession of that key has
               complete control of all data and actions to which the integration has access.

               Either this key or all of "integration_key", "secret_key", and "api_hostname" must
               be provided.  If both this key and some of those keys are provided, their values
               will override the values retrieved from the "key_file" file.

           secret_key
               The secret key returned by Duo when the API integration was created.  This is
               security-sensitive information equivalent to a password.  Anyone in possession of
               that key has complete control of all data and actions to which the integration has
               access.  Do not hard-code this into programs; instead, read it from a file with
               appropriate permissions or retrieve it via some other secure mechanism.

               This key is required if "key_file" is not set.

           user_agent
               The user agent to use for all requests.  This should be a Perl object that
               supports the same API as LWP::UserAgent.

               Normally, the caller will not provide this key, in which case Net::Duo will create
               an LWP::UserAgent object internally to use to make Duo API calls.  This argument
               is provided primarily so that the user agent can be overridden for unit testing.

INSTANCE METHODS

       call(METHOD, PATH[, ARGS])
           Make a generic Duo API call, with no assumptions about the response.

           This is a low-level escape hatch to make any Duo API call that this module does not
           know about, regardless of what format in which it returns its results.  The caller
           will have to provide all of the details (HTTP method, URL path, and all arguments as a
           reference to a hash of key/value pairs).  The URL path must start with a slash.

           The return value is the resulting HTTP::Response object from the web API call.  No
           error checking will be performed.  The caller is responsible for examining the
           HTTP::Response object for any problems, including internal or HTTP errors.

           Most Duo API calls return structured JSON and follow a standard pattern for indicating
           errors.  For those calls, use call_json() instead of this method.  call() is needed
           only for the small handful of API calls that do not return JSON in that format, such
           as the Auth API "/logo" endpoint.

       call_json(METHOD, PATH[, ARGS])
           Make a generic Duo API call that returns a JSON response.

           This is the escape hatch to use to make any Duo API call that this module does not
           know about.  The caller will have to provide all of the details (HTTP method, URL
           path, and all arguments as a reference to a hash of key/value pairs).  The URL path
           must start with a slash.

           The return value will be only the value of the response key from the returned JSON.
           This method still handles checking the "stat" value from Duo and throwing a
           Net::Duo::Exception object on call failure.

           This method cannot be used with the small handful of API calls that do not return
           JSON, such as the Auth API "/logo" endpoint.
