=head1 NAME

Net::Simplify::AccessToken - Simplify Commerce OAuth access token

=head1 SYNOPSIS

  use Net::Simplify;

  my $auth_code = "YOUR AUTH CODE";
  my $redirect_uri = "YOUR REDIRECT URI";

  my $token = Net::Simplify::AccessToken->create($auth_code, $redirect_uri);
  printf "Access token %s\n", $token->access_token;

  # Create Authentication object using the access token
  my $auth = Net::Simplify::Authentication->create({
        public_key => 'YOUR PUBLIC_KEY',
        private_key => 'YOUR PRIVATE KEY',
        access_token => $token->access_token
  });

  # Create a payment using the OAuth credentials
  my $payment = Net::Simplify::Payment->create({...}, $auth);


=head1 DESCRIPTION

Access tokens provide a way of performing operations on behalf of another user.  To create
an access token an authentication code is required.  Once the access token has been created
the access token value can be used to construct an L<Net::Simplify::Authentication>
object which can be passed to API calls.

=head2 METHODS

=head3 create($auth_code, $redirect_uri, $auth) 

Creates an AccessToken object.  The parameters are:

=over 4

=item C<$auth_code>

The authentication code obtained during the OAuth login process.

=item C<$redirect_uri>

The redirect URI for the OAuth login process.  This must match the registered value.

=item C<$auth>

Authentication object for accessing the API.  If no value is passed the global keys
C<$Net::Simplify::public_key> and C<$Net::Simplify::private_key> are used.

=back

=head3 refresh()

Refresh the token obtaining new access and refresh tokens.  Authentication is done
using the same credentials used when the AccessToken was created.

=head3 revoke()

Revokes the access token.  Authentication is done using the same credentials used when the AccessToken was created.

=head3 access_token($value)

Returns the current value of the access token.
If the $value parameter is passed in it is used to set the value of the access token.


=head3 refresh_token($value)

Returns the current value of the refresh token.
If the $value parameter is passed in it is used to set the value of the refresh token.

=head3 expires_in($value)


Returns the period in seconds since the access token was created or refreshed to when
the token expires.
If the $value parameter is passed in it is used to set the value of the expiry.
