}
DESCRIPTION
This module provides a perl interface to the Twitter APIs. See
<http://apiwiki.twitter.com/Twitter-API-Documentation> for a full
description of the Twitter APIs.
OMG! THE MOOSE!
Net::Twitter is Moose based. Moose provides some advantages, including
the ability for the maintainer of this module to respond quickly to
Twitter API changes.
See Net::Twitter::Lite if you need an alternative without Moose and its
dependencies.
Net::Twitter::Lite's API method definitions and documentation are
generated from Net::Twitter. It is a related module, but does not depend
on Net::Twitter or Moose for installation.
METHODS AND ARGUMENTS
new This constructs a "Net::Twitter" object. It takes several named
parameters, all of them optional:
traits
An ARRAY ref of traits used to control which APIs the
constructed "Net::Twitter" object will support and how it
handles errors. Possible values are:
API::REST
Provides support for the Twitter REST API methods.
API::Search
Provides support for the Twitter Search API methods.
API::TwitterVision
Provides support for the TwitterVision API. See
<http://twittervision.com/api.html>.
WrapError
"Net::Twitter" normally throws exceptions on error. When
this trait is included, "Net::Twitter" returns undef when a
method fails and makes the error available through method
"get_error". This is the way all errors were handled in
Net::Twitter versions prior to version 3.00.
OAuth
The "OAuth" trait provides OAuth authentication rather than
the default Basic Authentication for Twitter API method
calls. See the "Authentication" section and
Net::Twitter::Role::OAuth for full documentation.
InflateObjects
When this optional trait is included, Net::Twitter inflates
HASH refs returned by Twitter into objects with read
accessors for each element. In addition, it inflates dates
to DateTime objects and URLs to URI objects. Objects that
include a "created_at" attribute also have a
"relative_created_at" method.
For example, with "InflateObjects" applied, the
<friends_timeline> method returns an array of status
objects:
$r = $nt->friends_timeline;
for my $status ( @$r ) {
$r->user->screen_name; # same as $r->{user}{screen_name}
# $created_at is a DateTime; $age is a DateTime::Duration
my $age = DateTime->now - $r->created_at;
# print an age in a similar style to the Twitter web site, e.g.:
# less than a minute ago
# about a minute ago
# 6 minutes ago
# 1 day ago
# etc.
print $r->relative_created_at;
Legacy
This trait provides backwards compatibility to
"Net::Twitter" versions prior to 3.00. It implies the traits
"API::REST", "API::Search", "API::TwitterVision", and
"API::WrapError". It also provides additional functionality
to ensure consistent behavior for applications written for
use with legacy versions of "Net::Twitter".
In the current version, this trait is automatically included
if the "traits" option is not specified. This ensures
backwards compatibility for existing applications using
"Net::Twitter" versions prior to 3.00. See section "LEGACY
COMPATIBILITY" for more details.
Some examples of using the "traits" parameter in "new":
# provide support for *only* the REST API; throw exceptions on error
$nt = Net::Twitter->new(traits => ['API::REST']);
# provide support for both the REST and Search APIs; wrap errors
$nt = Net::Twitter->new(traits => [qw/API::REST API::Search WrapError/]);
# ensure full legacy support
$nt = Net::Twitter->new(traits => ['Legacy']);
# currently, these 2 calls to new are equivalent:
$nt = Net::Twitter->new();
$nt = Net::Twitter->new(traits => ['Legacy']);
legacy
A boolean. If set to 0, "new" constructs a "Net::Twitter" object
implementing the REST API and throws exceptions on API method
errors.
Net::Twitter->new(legacy => 0);
is a shortcut for:
Net::Twitter->new(traits => ['API::REST']);
If set to 1, "new" constructs a "Net::Twitter" object with the
"Legacy" trait.
Net::Twitter->new(legacy => 1);
is a shortcut for:
Net::Twitter->new(traits => ['Legacy']);
username
This is the screen name or email used to authenticate with
Twitter.
password
This is the password used to authenticate with Twitter.
clientname
The value for the "X-Twitter-Client-Name" HTTP header. It
defaults to "Perl Net::Twitter".
clientver
The value for the "X-Twitter-Client-Version" HTTP header. It
defaults to current version of the "Net::Twitter" module.
clienturl
The value for the "X-Twitter-Client-URL" HTTP header. It
defaults to the search.cpan.org page for the "Net::Twitter"
distribution.
useragent_class
The "LWP::UserAgent" compatible class used internally by
"Net::Twitter". It defaults to "LWP::UserAgent". For POE based
applications, consider using "LWP::UserAgent::POE".
useragent_args
An HASH ref of arguments to pass to constructor of the class
specified with "useragent_class", above. It defaults to {} (an
empty HASH ref).
useragent
The value for "User-Agent" HTTP header. It defaults to
"Net::Twitter/$VERSION (Perl)", where $VERSION is the current
version of "Net::Twitter".
source
The value used in the "source" parameter of API method calls. It
is currently only used in the "update" method in the REST API.
It defaults to "twitterpm". This results in the text "from
Net::Twitter" rather than "from web" for status messages posted
from "Net::Twitter" when displayed via the Twitter web
interface.
Twitter is no longer registering source parameters. New
applications should implement OAuth and register via
<http://twitter.com/oauth_clients>.
Only use the "source" parameter if you have an existing,
registered source parameter from Twitter.
apiurl
The URL for the Twitter API. This defaults to
"http://twitter.com". This option is available when the
"API::REST" trait is included.
apihost
A string containing the Twitter API host. It defaults to
"twitter.com:80". This option is available when the "API::REST"
trait is included.
apirealm
A string containing the Twitter API realm used for Basic
Authentication. It defaults to "Twitter API". This option is
available when the "API::REST" trait is included.
identica
If set to 1, "Net::Twitter" overrides the defaults for "apiurl",
"apihost", and "apirealm" to "http://identi.ca/api",
"identi.ca:80", and "Laconica API" respectively. It defaults to
0. This option is available when the "API::REST" trait is
included.
consumer_key
A string containing the OAuth consumer key provided by Twitter
when an application is registered. This option is available when
the "OAuth" trait is included.
consumer_secret
A string containing the OAuth consumer secret. This option is
available when the "OAuth" trait is included.
ssl If set to 1, an SSL connection will be used for all API calls.
Defaults to 0.
netrc
If set to 1, Net::Twitter will look up the host portion of the
"apiurl" in the ".netrc" file to obtain the u"username" and
"password" arguments.
# in .netrc
machine twitter.com
login YOUR_TWITTER_USER_NAME
password YOUR_TWITTER_PASSWORD
# in your perl program
$nt = Net::Twitter->new(netrc => 1);
decode_html_entities
Twitter encodes HTML entities in the "text" field of statuses.
Set this option to 1 to have them automatically decoded. Default
0.
credentials($username, $password)
Set the credentials for Basic Authentication. This is helpful for
managing multiple accounts.
ua Provides access to the constructed user agent object used internally
by "Net::Twitter". Use it with caution.
AUTHENTICATION
Twitter currently provides two authentication strategies: Basic
Authentication and OAuth. OAuth is officially in beta, however, Twitter
has expressed a desire to deprecate Basic Authentication in the future,
so consider using OAuth in your applications.
To set up Basic Authentication in "Net::Twitter", provide the "username"
and "password" options to "new" or call the "credentials" method.
To set up OAuth, include the "OAuth" trait and include the
"consumer_key" and "consumer_secret" options to "new". See
Net::Twitter::Role::OAuth for more information on using OAuth, including
examples.
In addition to the arguments specified for each API method described
below, an additional "authenticate" parameter can be passed. To request
an "Authorization" header, pass "authenticated => 1"; to suppress an
authentication header, pass "authentication => 0". Even if requested, an
Authorization header will not be added if there are no user credentials
(username and password for Basic Authentication; access tokens for
OAuth).
This is probably only useful for the "rate_limit_status" method in the
REST API, since it returns different values for an authenticated and a
non-authenticated call.
API METHODS AND ARGUMENTS
Most Twitter API methods take parameters. All Net::Twitter API methods
will accept a HASH ref of named parameters as specified in the Twitter
API documentation. For convenience, many Net::Twitter methods accept
simple positional arguments as documented, below. The positional
parameter passing style is optional; you can always use the named
parameters in a hash ref if you prefer.
For example, the REST API method "update" has one required parameter,
"status". You can call "update" with a HASH ref argument:
$nt->update({ status => 'Hello world!' });
Or, you can use the convenient form:
$nt->update('Hello world!');
The "update" method also has an optional parameter,
"in_reply_to_status_id". To use it, you must use the HASH ref form:
$nt->update({ status => 'Hello world!', in_reply_to_status_id => $reply_to });
Convenience form is provided for the required parameters of all API
methods. So, these two calls are equivalent:
$nt->friendship_exists({ user_a => $fred, user_b => $barney });
$nt->friendship_exists($fred, $barney);
Many API methods have aliases. You can use the API method name, or any
of its aliases, as you prefer. For example, these calls are all
equivalent:
$nt->friendship_exists($fred, $barney);
$nt->relationship_exists($fred, $barney);
$nt->follows($fred, $barney);
Aliases support both the HASH ref and convenient forms:
$nt->follows({ user_a => $fred, user_b => $barney });
Methods that support the "page" parameter expect page numbers > 0.
Twitter silently ignores invalid "page" values. So "{ page => 0 }"
produces the same result as "{ page => 1 }".
Synthetic Arguments
In addition to the arguments described in the Twitter API Documentation
for each API method, Net::Twitter supports additional *synthetic*
arguments.
authenticate
When set to 1, Net::Twitter will provide an Authorization header for
the API call; when set to 0, it will suppress the Authentication
header. This argument overrides the defined authentication behavior
for the API method. It is probably only useful for the
"rate_limit_satus" method which returns different values for
authenticated and unauthenticated calls. See "AUTHENTICATION" for
more details.
since
API methods that accept the "since_id" argument will also accept the
synthetic "since" argument, instead. "since" may be a "Date::Time"
object, an epoch time (the number of seconds since the system
epoch), or a string in the same format returned by Twitter for the
"created_at" attribute. Only status with a "created_at" time greater
than "since" will be returned by the API call.
REST API Methods
These methods are provided when trait "API::REST" is included in the
"traits" option to "new".
Several of these methods accept a user ID as the "id" parameter. The
user ID can be either a screen name, or the users numeric ID. To
disambiguate, use the "screen_name" or "user_id" parameters, instead.
For example, These calls are equivalent:
$nt->create_friend('net_twitter'); # screen name
$nt->create_friend(1564061); # numeric ID
$nt->create_friend({ id => 'net_twitter' });
$nt->create_friend({ screen_name => 'net_twitter' });
$nt->create_friend({ user_id => 1564061 });
However user_id 911 and screen_name 911 are separate Twitter accounts.
These calls are NOT equivalent:
$nt->create_friend(911); # interpreted as screen name
$nt->create_friend({ user_id => 911 }); # screen name: richellis
Whenever the "id" parameter is required and "user_id" and "screen_name"
are also parameters, using any one of them satisfies the requirement.

Returns: HashRef|ArrayRef[Int]
friends_timeline
alias: following_timeline
Parameters: since_id, max_id, count, page
Required: *none*
Returns the 20 most recent statuses posted by the authenticating
user and that user's friends. This is the equivalent of /home on the
Web.
Returns: ArrayRef[Status]
friendship_exists
friendship_exists(user_a, user_b)
alias: relationship_exists
alias: follows
Parameters: user_a, user_b
Required: user_a, user_b
Tests for the existence of friendship between two users. Will return
true if user_a follows user_b, otherwise will return false.
Returns: Bool
home_timeline
Parameters: since_id, max_id, count, page
Required: *none*
Returns the 20 most recent statuses, including retweets, posted by
the authenticating user and that user's friends. This is the
equivalent of /timeline/home on the Web.
Returns: ArrayRef[Status]
mentions
alias: replies
Parameters: since_id, max_id, count, page
Required: *none*
Returns the 20 most recent mentions (statuses containing @username)
for the authenticating user.
Returns: ArrayRef[Status]
new_direct_message
new_direct_message(user, text)
Parameters: user, text, screen_name, user_id
Required: user, text
Sends a new direct message to the specified user from the
authenticating user. Requires both the user and text parameters.
Returns the sent message when successful. In order to support
numeric screen names, the "screen_name" or "user_id" parameters may
be used instead of "user".
Returns: DirectMessage
public_timeline
Parameters: *none*
Required: *none*
Returns the 20 most recent statuses from non-protected users who
have set a custom user icon. Does not require authentication. Note
that the public timeline is cached for 60 seconds so requesting it
more often than that is a waste of resources.
If user credentials are provided, "public_timeline" calls are
authenticated, so they count against the authenticated user's rate
limit. Use "->public_timeline({ authenticate => 0 })" to make an
unauthenticated call which will count against the calling IP
address' rate limit, instead.
Returns: ArrayRef[Status]
rate_limit_status
Parameters: *none*
Required: *none*
Returns the remaining number of API requests available to the
authenticated user before the API limit is reached for the current
hour.
Use "->rate_limit_status({ authenticate => 0 })" to force an
unauthenticated call, which will return the status for the IP
address rather than the authenticated user. (Note: for a web
application, this is the server's IP address.)
Returns: RateLimitStatus
retweet
retweet(id)
Parameters: id
Required: id
Retweets a tweet. Requires the id parameter of the tweet you are
retweeting. Returns the original tweet with retweet details
embedded.
Returns: Status

screen name as per the required id parameter. This information
includes design settings, so third party developers can theme their
widgets according to a given user's preferences. You must be
properly authenticated to request the page of a protected user.
Returns: ExtendedUser
test
Parameters: *none*
Required: *none*
Returns the string "ok" status code.
Returns: Str
update
update(status)
Parameters: status, in_reply_to_status_id
Required: status
Updates the authenticating user's status. Requires the status
parameter specified. A status update with text identical to the
authenticating user's current status will be ignored.
Returns: Status
update_delivery_device
update_delivery_device(device)
Parameters: device
Required: device
Sets which device Twitter delivers updates to for the authenticating
user. Sending none as the device parameter will disable IM or SMS
updates.
Returns: BasicUser
update_profile
Parameters: name, email, url, location, description
Required: *none*
Sets values that users are able to set under the "Account" tab of
their settings page. Only the parameters specified will be updated;
to only update the "name" attribute, for example, only include that
parameter in your request.
Returns: ExtendedUser
update_profile_background_image
update_profile_background_image(image)
Parameters: image
Required: image
Updates the authenticating user's profile background image. The
"image" parameter must be an arrayref with the same interpretation
as the "image" parameter in the "update_profile_image" method. See
that method's documentation for details.
Returns: ExtendedUser
update_profile_colors
Parameters: profile_background_color, profile_text_color,
profile_link_color, profile_sidebar_fill_color,
profile_sidebar_border_color
Required: *none*
Sets one or more hex values that control the color scheme of the
authenticating user's profile page on twitter.com. These values are
also returned in the /users/show API method.
Returns: ExtendedUser
update_profile_image
update_profile_image(image)
Parameters: image
Required: image
Updates the authenticating user's profile image. The "image"
parameter is an arrayref with the following interpretation:
[ $file ]
[ $file, $filename ]
[ $file, $filename, Content_Type => $mime_type ]
[ undef, $filename, Content_Type => $mime_type, Content => $raw_image_data ]
The first value of the array ($file) is the name of a file to open.
The second value ($filename) is the name given to Twitter for the
file. If $filename is not provided, the basename portion of $file is
used. If $mime_type is not provided, it will be provided
automatically using LWP::MediaTypes::guess_media_type().
$raw_image_data can be provided, rather than opening a file, by
passing "undef" as the first array value.
Returns: ExtendedUser
user_timeline
Parameters: id, user_id, screen_name, since_id, max_id, count, page
Required: *none*
Returns the 20 most recent statuses posted from the authenticating
user. It's also possible to request another user's timeline via the
id parameter. This is the equivalent of the Web /archive page for
your own user, or the profile page for a third party.
Returns: ArrayRef[Status]
verify_credentials
Parameters: *none*
Required: *none*
Returns an HTTP 200 OK response code and a representation of the
requesting user if authentication was successful; returns a 401
status code and an error message if not. Use this method to test if
supplied user credentials are valid.

LEGACY COMPATIBILITY
This version of "Net::Twitter" automatically includes the "Legacy" trait
if no "traits" option is provided to "new". Therefore, these 2 calls are
currently equivalent:
$nt = Net::Twitter->new(username => $user, password => $passwd);
$nt = Net::Twitter->new(
username => $user,
password => $passwd,
traits => ['Legacy'],
);
Thus, existing applications written for a prior version of
"Net::Twitter" should continue to run, without modification, with this
version.
In a future release, the default traits may change. Prior to that
change, however, a nearer future version will add a warning if no
"traits" option is provided to "new". To avoid this warning, add an
appropriate "traits" option to your existing application code.
ERROR HANDLING
There are currently two strategies for handling errors: throwing
exceptions and wrapping errors. Exception handling is the newer,
recommended strategy.
Wrapping Errors
When trait "WrapError" is specified (or "Legacy", which includes trait
"WrapError"), "Net::Twitter" returns undef on error. To retrieve
information about the error, use methods "http_code", "http_message",
and "get_error". These methods are described in the
Net::Twitter::Role::WrapError.
if ( my $followers = $nt->followers ) {
for my $follower ( @$followers ) {
#...
}
}
else {
warn "HTTP message: ", $nt->http_message, "\n";
}
Since an error is stored in the object instance, this error handling
strategy is problematic when using a user agent like
"LWP::UserAgent::POE" that provides concurrent requests. The error for
one request can be overwritten by a concurrent request before you have
an opportunity to access it.
Exception Handling
When "Net::Twitter" encounters a Twitter API error or a network error,
it throws a "Net::Twitter::Error" object. You can catch and process
these exceptions by using "eval" blocks and testing $@:
eval {
my $statuses = $nt->friends_timeline(); # this might die!
for my $status ( @$statuses ) {
#...
}
};
if ( $@ ) {
# friends_timeline encountered an error
if ( blessed $@ && $@->isa('Net::Twitter::Error') ) {
#... use the thrown error obj
warn $@->error;
}
else {
# something bad happened!
die $@;
}
}
"Net::Twitter::Error" stringifies to something reasonable, so if you
don't need detailed error information, you can simply treat $@ as a
string:
eval { $nt->update($status) };
if ( $@ ) {
warn "update failed because: $@\n";
}
FAQ
Why does "->followers({ screen_name => $friend })" return *my* followers
instead of $friends's?
First, check carefully to make sure you've spelled "screen_name"
correctly. Twitter sometimes discards parameters it doesn't
recognize. In this case, the result is a list of your own
followers---the same thing that would happen if you called
"followers" without the "screen_name" parameter.
How do I use the "geocode" parameter in the Search API?
The "geocode" parameter value includes a latitude, longitude, and
radius separated with commas.
$r = $nt->search({ geocode => "45.511795,-122.675629,25mi" });
