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.
