NAME

       LWP::Authen::OAuth2::ServiceProvider::Line - Access Line OAuth2 API v2

VERSION

       version 0.20

SYNOPSIS

           my $oauth2 = LWP::Authen::OAuth2->new(
               service_provider => 'Line',
               redirect_uri     => 'http://example.com/',
               client_id        => 'line_client_id'      # Retrieved from https://developers.line.me/
               client_secret    => 'line_client_secret'  # Retrieved from https://developers.line.me/
           );

           my $url = $oauth2->authorization_url(state => $state);

           # ... Send user to authorization URL and get authorization $code ...

           $oauth2->request_tokens(code => $code);

           # Simple requests

           # User Info
           my $profile       = $oauth2->make_api_call('profile');
           my $userId        = $profile->{userId};
           my $displayName   = $profile->{displayName};
           my $pictureUrl    = $profile->{pictureUrl};
           my $statusMessage = $profile->{statusMessage};

           # Refresh
           $oauth2->refresh_access_token();

           # More complex requests...

           # Verify
           # Manually send the request using the internal user agent - see explanation in "Line API Documentation" below.
           my $access_token_str = $oauth2->access_token->access_token;
           my $res = $oauth2->user_agent->post($oauth2->api_url_base.'oauth/verify' => { access_token => $access_token_str });
           my $content = eval { decode_json($res->content) };
           my $scope      = $content->{scope};
           my $client_id  = $content->{client_id};
           my $expires_in = $content->{expires_in};

           # Revoke
           # Look up the internal refresh token - see explanation in "Line API Documentation" below.
           my $refresh_token_str = $oauth2->access_token->refresh_token;
           $oauth2->post($oauth2->api_url_base.'oauth/revoke' => { refresh_token => $refresh_token_str });

REGISTERING

       Individual users must have an account created with the Line application
       <https://line.me/download>.  In order to log in with OAuth2, users must register their
       email address. Device-specific instructions can be found on the Line support site
       <https://help.line.me/>.

       API clients can follow the Line Login <https://developers.line.me/line-login/overview>
       documentation to set up the OAuth2 credentials.

Line API Documentation

       See the Line Social REST API Reference <https://devdocs.line.me/en/#how-to-use-the-apis>.

       As of writing, there are two simple API calls: "profile" and "refresh".

       There are also "verify" and "revoke" endpoints, which require a bit more work.

       "verify"
           "verify" is designed for verifying pre-existing access tokens. Instead of using the
           "Authorization" header, this endpoint expects the access token to be form-urlencoded
           in the request body. Because of this, it's necessary to get access to the internal
           access token string to send in the request body. The
           LWP::Authen::OAuth2::ServiceProvider::Line::AccessToken token class used by this
           service provider provides the "access_token" accessor for this purpose.

           The server seems to ignore the "Authorization" header for this request, so including
           it is probably not a problem. If you want to avoid sending the access token in the
           header, it's necessary to manually construct the request and decode the response.

           See "SYNOPSIS" for usage examples.

       "revoke"
           "revoke" requires the refresh token to be form-urlencoded in the request body. Because
           of this, it's necessary to get access to the internal refresh token string to send in
           the request body. The LWP::Authen::OAuth2::ServiceProvider::Line::AccessToken token
           class used by this service provider provides the "refresh_token" accessor for this
           purpose. See "SYNOPSYS" for usage examples.

Refresh timing

       Line access tokens can be refreshed at any time up until 10 days after the access token
       expires. The LWP::Authen::OAuth2::ServiceProvider::Line::AccessToken token class used by
       this service provider extends the "should_refresh" method for this purpose, causing
       "$oauth2->should_refresh()" to return false if this 10-day period has lapsed.
