       Net::Twitter::Manual::MigratingToV1_1 - Migrating from Twitter API v1 to v1.1

VERSION

       version 4.01043

SYNOPSIS

           use Net::Twitter

           my $nt = Net::Twitter->new(
               traits              => [qw/API::RESTv1_1/],
               consumer_key        => $consumer_key,
               consumer_secret     => $consumer_secret,
               access_token        => $access_token,
               access_token_secret => $access_token_secret,
           );

DESCRIPTION

       Net::Twitter prior to version 4.0 used Twitter API version 1. Twitter API v1.1 introduced changes that
       are not entirely backwards compatible, requiring some changes to calling code.

       Net::Twitter attempts to provided backwards compatibility where possible. This document describes the
       changes required to your existing application code, using Net::Twitter, for use with Twitter's API v1.1.

FIRST

   Include the API::RESTv1_1 trait
       Wherever you create a Net::Twitter object by calling "new", replace trait "API::REST" with
       "API::RESTv1_1". For most applications, that's all that is required.

EXCEPTIONS

       Trait RateLimit incompatible with API::RESTv1_1
           The  "RateLimit"  trait  is  incompatible  with  Twitter  API  v1.1. Rate limiting is one of the most
           extensive changes in v1.1. In v1  there  were  two  hourly  rate  limits,  one  per  IP  address  for
           unauthenticated  calls, and one per-user/application for authenticated calls. In v1.1, all calls must
           be authenticated, and each API endpoint (i.e., each method) has it's  own  rate  limit.  Rather  than
           hourly, the new rate limits operate on a 15 minute window.

           If  your  code  currently  uses  the  "RateLimit" role, you'll need to write some custom code provide
           equivalent functionality.

       rate_limit_status
           The return value for "rate_limit_status" is entirely different. See Twitter's  API  rate_limit_status
           <https://dev.twitter.com/docs/api/1.1/get/application/rate_limit_status> documentation for details.

       blocking
       blocking_ids
       friends
       followers
           With  API  v1.1,  these  methods  use  cursor  based paging. If you do not pass a "cursor" parameter,
           Twitter assumes "cursor => -1">. Existing code that expects an arrayref return value must be modified
           to expect a hashref and dereference the "users" slot:

               # With API v1
               my $r = $nt->friends;
               my @friends = @$r;

               # With API v1.1
               my $r = $nt->friends;
               my @friends = @{$r->{users}};

       search
           The "search" method semantics and return value are substantially different between Twitter API v1 and
           v1.1. In v1, "search" was provided by the "API::Search" trait. In v1.1, "search" is included  in  the
           "API::RESTv1_1" trait.

           So,  first, drop "API::Search" from your calls to "new". The "API::Search" trait is incompatible with
           "API::RESTv1_1".

           In v1, Twitter returned a hashref with several keys containing meta data. The actual array of results
           were contained in the "results" slot:

               # With Twitter API v1
               my $nt = Net::Twitter->new(traits => [qw/API::REST API::Search/]);

               my $r = $nt->search('perl hacker');
               for my $status ( @{$r->{results} ) {
                   # process each status...
               }

           In v1.1, Twitter returns a hash with 2 slots: "search_metadata" and "statuses".

               # With Twitter API v1.1
               my $nt = Net::Twitter->new(traits => [qw/API::RESTv1_1/], %oauth_credentials);

               my $r = $nt->search('perl hacker');
               for my $status ( @{$r->{statuses} ) {
                   # process each status...
               }

           Paging through search results works differently in v1.1. In v1, Twitter offered a "page" parameter:

               # With Twitter API v1
               for ( my $page = 1; $page <= 10; ++$page ) {
                   my $r = $nt->search({ q => $query, page => $page, rpp => 100 });
                   last unless @{$r->{results}};

                   # process a page of results...
               }

           In v1.1, use "max_id" and "count" to get paged results:

               # With Twitter API v1.1
               for ( my %args = ( q => $query, count => 100 ), my $n = 0; $n < 1000; ) {
                   my $r = $nt->search({ %args });
                   last unless @{$r->{statuses}};

                   $args{max_id} = $r->{statuses}[-1]{id} - 1;
                   $n += @{$r->{statuses}};

                   # process a page of results...
               }

   DEPRECATED METHODS
       Some Twitter API v1 methods are not available in v1.1:

       friends_timeline
           Use "home_timeline" instead.

       friendship_exists
       relationship_exists
       follows
           "friendship_exists" and it's aliases are not supported in API v1.1. Use "show_friendship" instead:

               my $r = $nt->show_relationship({
                   source_screen_name => $user_a,
                   target_screen_name => $user_b,
               });
               if ( $r->{relationship}{source}{following} ) {
                   # $user_a follows $user_b
               }
