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.
RETURN VALUES
Net::Twitter decodes the data structures returned by the Twitter API into native perl data structures (HASH references and ARRAY references). The full layout of those data structures are not documented, here. They change often, usually with the addition of new elements, and documenting all of those changes would be a significant challenge.
Instead, rely on the online Twitter API documentation and inspection of the returned data.
The Twitter API online documentation is located at http://apiwiki.twitter.com/Twitter-API-Documentation.
To inspect the data, use Data::Dumper or similar module of your choice. Here's a simple example using Data::Dumper:
use Data::Dumper;
my $r = $nt->search($search_term);
print Dumper $r;
For more information on perl data structures, see perlreftut, perldsc, and perllol.
METHODS AND ARGUMENTS
- new
-
This constructs a
Net::Twitter
object. It takes several named parameters, all of them optional:- traits
-
An ARRAY ref of traits used to control which APIs the constructed
Net::Twitter
object will support and how it handles errors. Possible values are:- API::REST
-
Provides support for the Twitter REST API methods.
- API::Search
-
Provides support for the Twitter Search API methods.
- API::TwitterVision
-
Provides support for the TwitterVision API. See http://twittervision.com/api.html.
- WrapError
-
Net::Twitter
normally throws exceptions on error. When this trait is included,Net::Twitter
returns undef when a method fails and makes the error available through methodget_error
. This is the way all errors were handled in Net::Twitter versions prior to version 3.00. - OAuth
-
The
OAuth
trait provides OAuth authentication rather than the default Basic Authentication for Twitter API method calls. See the "Authentication" section and Net::Twitter::Role::OAuth for full documentation. - InflateObjects
-
When this optional trait is included, Net::Twitter inflates HASH refs returned by Twitter into objects with read accessors for each element. In addition, it inflates dates to DateTime objects and URLs to URI objects. Objects that include a
created_at
attribute also have arelative_created_at
method.For example, with
InflateObjects
applied, the <friends_timeline> method returns an array of status objects:$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;
- RateLimit
-
The
RateLimit
trait adds utility methods that return information about the current rate limit status. See Net::Twitter::Role::RateLimit for details. - Legacy
-
This trait provides backwards compatibility to
Net::Twitter
versions prior to 3.00. It implies the traitsAPI::REST
,API::Search
,API::TwitterVision
, andAPI::WrapError
. It also provides additional functionality to ensure consistent behavior for applications written for use with legacy versions ofNet::Twitter
.In the current version, this trait is automatically included if the
traits
option is not specified. This ensures backwards compatibility for existing applications usingNet::Twitter
versions prior to 3.00. See section "LEGACY COMPATIBILITY" for more details.
Some examples of using the
traits
parameter innew
:# 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(); $nt = Net::Twitter->new(traits => ['Legacy']);
- legacy
-
A boolean. If set to 0,
new
constructs aNet::Twitter
object implementing the REST API and throws exceptions on API method errors.Net::Twitter->new(legacy => 0);
is a shortcut for:
Net::Twitter->new(traits => ['API::REST']);
If set to 1,
new
constructs aNet::Twitter
object with theLegacy
trait.Net::Twitter->new(legacy => 1);
is a shortcut for:
Net::Twitter->new(traits => ['Legacy']);
- username
-
This is the screen name or email used to authenticate with Twitter.
- password
-
This is the password used to authenticate with Twitter.
- clientname
-
The value for the
X-Twitter-Client-Name
HTTP header. It defaults to "Perl Net::Twitter". - clientver
-
The value for the
X-Twitter-Client-Version
HTTP header. It defaults to current version of theNet::Twitter
module. - clienturl
-
The value for the
X-Twitter-Client-URL
HTTP header. It defaults to the search.cpan.org page for theNet::Twitter
distribution. - useragent_class
-
The
LWP::UserAgent
compatible class used internally byNet::Twitter
. It defaults to "LWP::UserAgent". For POE based applications, consider using "LWP::UserAgent::POE". - useragent_args
-
An HASH ref of arguments to pass to constructor of the class specified with
useragent_class
, above. It defaults to {} (an empty HASH ref). - useragent
-
The value for
User-Agent
HTTP header. It defaults to "Net::Twitter/$VERSION (Perl)", where$VERSION
is the current version ofNet::Twitter
. - source
-
The value used in the
source
parameter of API method calls. It is currently only used in theupdate
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 fromNet::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://api.twitter.com/1". This option is available when the
API::REST
trait is included. - apihost
-
DEPRECATED - Setting the
apiurl
is sufficient. - 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 forapiurl
,apihost
, andapirealm
to "http://identi.ca/api", "identi.ca:80", and "Laconica API" respectively. It defaults to 0. This option is available when theAPI::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
-
(Optional) Sets the machine key to look up in
.netrc
to obtain credentials. If set to 1, Net::Twitter will use the value of thenetrc_machine
option (below).# in .netrc machine api.twitter.com login YOUR_TWITTER_USER_NAME password YOUR_TWITTER_PASSWORD machine semifor.twitter.com login semifor password SUPERSECRET # in your perl program $nt = Net::Twitter->new(netrc => 1); $nt = Net::Twitter->new(netrc => 'semifor.twitter.com');
- netrc_machine
-
(Optional) Sets the
machine
entry to look up in.netrc
when<netrc =
1>> is used. Defaults toapi.twitter.com
. - decode_html_entities
-
Twitter encodes HTML entities in the
text
field of statuses. Set this option to 1 to have them automatically decoded. Default 0.
- credentials($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 });
Cursors and Paging
Some methods return partial results a page at a time. Originally, methods that returned partial results used a page
parameter. A more recent addition to the Twitter API for retrieving multiple pages uses the cursor
parameter. Usually, a method uses either the page
parameter or the cursor
parameter, but not both. There have been exceptions to this rule when Twitter deprecates the use of page
for a method in favor of cursor
. In that case, both methods may work during a transition period. So, if a method supports both, you should always use the cursor
parameter.
Paging
For methods that support paging, the first page is returned by passing page => 1
, the second page by passing page => 2
, etc. If no page
parameter is passed, the first page is returned.
Here's an example that demonstrates how to obtain all favorites in a loop:
my @favs;
for ( my $page = 1; ; ++$page ) {
my $r = $nt->favorites({ page => $page });
last unless @$r;
push @favs, @$r;
}
Cursors
Cursoring employs a different strategy. To obtain the first page of results, pass cursor => -1
. Twitter returns a reference to a hash that includes entries next_cursor
, previous_cursor
, and an entry with a reference to an array containing a page of the requested items. The key for the array reference will be named users
, ids
, or something similar depending upon the type of returned items. For example, when cursor
parameter is used with the followers_ids
method, the returned in hash entry ids
.
The next_cursor
value can be used in a subsequent call to obtain the next page of results. When you have obtained the last page of results, next_cursor
will be 0. Likewise, you can use the value for previous_cursor
to obtain the previous page of results. When you have obtained the first page, previous_cursor
will be 0.
Here's an example that demonstrates how to obtain all follower IDs in a loop using the cursor
parameter:
my @ids;
for ( my $cursor = -1, my $r; $cursor; $cursor = $r->{next_cursor} ) {
$r = $nt->followers_ids({ cursor => $cursor });
push @ids, @{ $r->{ids} };
}
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 syntheticsince
argument, instead.since
may be aDate::Time
object, an epoch time (the number of seconds since the system epoch), or a string in the same format returned by Twitter for thecreated_at
attribute. Only statuses with acreated_at
time greater thansince
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
.
Common Parameters
- id
-
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 thescreen_name
oruser_id
parameters, instead.For example, These calls are equivalent:
$nt->create_friend('perl_api'); # screen name $nt->create_friend(1564061); # numeric ID $nt->create_friend({ id => 'perl_api' }); $nt->create_friend({ screen_name => 'perl_api' }); $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 anduser_id
andscreen_name
are also parameters, using any one of them satisfies the requirement. - skip_user
-
The timeline methods all accept an optional
skip_user
parameter. When set to a true value, the statuses returned in a timeline will not contain an entire embedded user HASH. Instead, the user node will contain only anid
element to indicate the numerical ID of the Twitter user that sent the status.

parameters may be used instead ofuser
.Returns: DirectMessage
- public_timeline
- public_timeline(skip_user)
-
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

to make an unauthenticated call which will count against the calling IP address' rate limit, instead.Returns: ArrayRef[Status]
- rate_limit_status
-
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 })

Returns: ArrayRef[Status]
- reverse_geocode
- reverse_geocode(lat, long)
-
Search for places (cities and neighborhoods) that can be attached to a statuses/update. Given a latitude and a longitude, return a list of all the valid places that can be used as a place_id when updating a status. Conceptually, a query can be made from the user's location, retrieve a list of places, have the user validate the location he or she is at, and then send the ID of this location up with a call to statuses/update.
There are multiple granularities of places that can be returned -- "neighborhoods", "cities", etc. At this time, only United States data is available through this method.
- lat
-
Required. The latitude to query about. Valid ranges are -90.0 to +90.0 (North is positive) inclusive.
- long
-
Required. The longitude to query about. Valid ranges are -180.0 to +180.0 (East is positive) inclusive.
- accuracy
-
Optional. A hint on the "region" in which to search. If a number, then this is a radius in meters, but it can also take a string that is suffixed with ft to specify feet. If this is not passed in, then it is assumed to be 0m. If coming from a device, in practice, this value is whatever accuracy the device has measuring its location (whether it be coming from a GPS, WiFi triangulation, etc.).
- granularity
-
Optional. The minimal granularity of data to return. If this is not passed in, then
neighborhood
is assumed.city
can also be passed. - max_results
-
Optional. A hint as to the number of results to return. This does not guarantee that the number of results returned will equal max_results, but instead informs how many "nearby" results to return. Ideally, only pass in the number of places you intend to display to the user here.
Returns: HashRef
- saved_searches
-
Returns the authenticated user's saved search queries.
Returns: ArrayRef[SavedSearch]

Returns: Status
- show_user
- show_user(id)
-
Returns extended information of a given user, specified by ID or 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
-
Returns the string "ok" status code.
Returns: Str
- trends_available
-
Returns the locations with trending topic information. The response is an array of "locations" that encode the location's WOEID (a Yahoo! Where On Earth ID http://developer.yahoo.com/geo/geoplanet/) and some other human-readable information such as a the location's canonical name and country.
When the optional
lat
andlong
parameters are passed, the available trend locations are sorted by distance from that location, nearest to farthest.Use the WOEID returned in the location object to query trends for a specific location.
Returns: ArrayRef[Location]
- trends_location
- trends_location(woeid)
-
Returns the top 10 trending topics for a specific location. The response is an array of "trend" objects that encode the name of the trending topic, the query parameter that can be used to search for the topic on Search, and the direct URL that can be issued against Search. This information is cached for five minutes, and therefore users are discouraged from querying these endpoints faster than once every five minutes. Global trends information is also available from this API by using a WOEID of 1.
Returns: ArrayRef[Trend]
- update
- update(status)
-
- Parameters: status, lat, long, place_id, display_coordinates, 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.
- status
-
Required. The text of your status update. URL encode as necessary. Statuses over 140 characters will cause a 403 error to be returned from the API.
- in_reply_to_status_id
-
Optional. The ID of an existing status that the update is in reply to. o Note: This parameter will be ignored unless the author of the tweet this parameter references is mentioned within the status text. Therefore, you must include @username, where username is the author of the referenced tweet, within the update.
- lat
-
Optional. The location's latitude that this tweet refers to. The valid ranges for latitude is -90.0 to +90.0 (North is positive) inclusive. This parameter will be ignored if outside that range, if it is not a number, if geo_enabled is disabled, or if there not a corresponding long parameter with this tweet.
- long
-
Optional. The location's longitude that this tweet refers to. The valid ranges for longitude is -180.0 to +180.0 (East is positive) inclusive. This parameter will be ignored if outside that range, if it is not a number, if geo_enabled is disabled, or if there not a corresponding lat parameter with this tweet.
- place_id
-
Optional. The place to attach to this status update. Valid place_ids can be found by querying
reverse_geocode
. - display_coordinates
-
Optional. By default, geo-tweets will have their coordinates exposed in the status object (to remain backwards compatible with existing API applications). To turn off the display of the precise latitude and longitude (but keep the contextual location information), pass
display_coordinates =
0> on the status update.
Returns: Status
- update_delivery_device
- update_delivery_device(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
-
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)
-
Updates the authenticating user's profile background image. The
image
parameter must be an arrayref with the same interpretation as theimage
parameter in theupdate_profile_image
method. See that method's documentation for details.Returns: ExtendedUser
- update_profile_colors
-
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)
-
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 passingundef
as the first array value.Returns: ExtendedUser
- user_timeline
-
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]
- users_search
- users_search(q)
- alias: find_people
- alias: search_users
-
Run a search for users similar to Find People button on Twitter.com; the same results returned by people search on Twitter.com will be returned by using this API (about being listed in the People Search). It is only possible to retrieve the first 1000 matches from this API.
Returns: ArrayRef[Users]
- verify_credentials

Lists API
For Lists API support, add trait API::Lists
to the traits
option in new
.
For full documentation of the Lists API, see Net::Twitter::Role::API::Lists.
use Net::Twitter;
my $nt = Net::Twitter->new(traits => ['API::Lists'], ...);
$list = $nt->create_list($owner, { name => $name, description => $desc });
$list = $nt->update_list($owner, $list_id, { description => $desc });
$lists = $nt->get_lists($owner);
$lists = $nt->list_lists($owner);
$list = $nt->get_list($owner, $list_id);
$list = $nt->delete_list($owner, $list_id);
$statuses = $nt->list_statuses($owner, $list_id);
$lists = $nt->list_memberships($owner);
$lists = $nt->list_subscriptions($owner);
$users = $nt->list_members($owner, $list_id);
$user_or_undef = $nt->list_members($owner, $list_id, { id => $user_id });
$user = $nt->add_list_member($owner, $list_id, $user_id);
$user = $nt->delete_list_member($owner, $list_id, $user_id);
$user = $nt->remove_list_member($owner, $list_id, $user_id);
$user_or_undef = $nt->is_list_member($owner, $list_id, $user_id);
$users = $nt->list_subscribers($owner, $list_id);
$list = $nt->subscribe_list($owner, $list_id);
$list = $nt->unsubscribe_list($owner, $list_id);
$user_or_undef = $nt->is_subscribed_list($owner, $list_id, $user_id);
$user_or_undef = $nt->is_list_subscriber($owner, $list_id, $user_id);
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 thescreen_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 = $nt->search({ geocode => "45.511795,-122.675629,25mi" });
- How do I get Twitter to display something other than "from Perl Net::Twitter"?
-
If you set the source parameter to
api
, twitter will display "from API", and if you set it to the empty string, twitter will display, "from web".$nt = Net::Twitter->new(netrc => 1,legacy => 0,ssl => 1,source => 'api'); $nt->update('A post with the source parameter overridden.'); # result: http://twitter.com/semifor_test/status/6541105458 $nt = Net::Twitter->new(netrc => 1,legacy => 0,ssl => 1,source => ''); $nt->update('A post with the source parameter overridden.'); # result: http://twitter.com/semifor_test/status/6541257224
If you want something other than "Net::Twitter", "API", or "web", you need to register an application and use OAuth authentication. If you do that, you can have any name you choose for the application printed as the source. Since rolling out OAuth, Twitter has stopped issuing new registered source parameters, only existing register source parameters are valid.
