=head1 NAME

Net::Twitter::Role::AppAuth - OAuth2 Application Only Authentication

=head1 VERSION

version 4.01043

=head1 SYNOPSIS

use Net::Twitter;

my $nt = Net::Twitter->new(
      traits          => ['API::RESTv1_1', 'AppAuth'],
      consumer_key    => "YOUR-CONSUMER-KEY",
      consumer_secret => "YOUR-CONSUMER-SECRET",
  );

$nt->request_token;

my $tweets = $nt->user_timeline({ screen_name => 'Twitter' });

=head1 DESCRIPTION

Net::Twitter::Role::OAuth is a Net::Twitter role that provides OAuth
authentication instead of the default Basic Authentication.

Note that this client only works with APIs that are compatible to OAuth authentication.

=head1 METHODS

=over 4

=item authorized

True if the client has an access_token. This does not check the validity of the
access token, so requests may fail if it is invalid.

=item request_access_token

Request an access token. Returns the token as well as saving it in the object.

=item access_token

Get or set the access token.

=item invalidate_token

Invalidates and clears the access_token.

Note: There seems to be a Twitter bug preventing this from working---perhaps a
documentation bug. E.g., see: L<https://twittercommunity.com/t/revoke-an-access-token-programmatically-always-getting-a-403-forbidden/1902>
