NAME

Net::Twitter - Perl interface to twitter.com

VERSION

This document describes Net::Twitter version 1.08

SYNOPSIS

   #!/usr/bin/perl

   use Net::Twitter;

   my $twit = Net::Twitter->new(username=>"myuser", password=>"mypass" );

   $result = $twit->update("My current Status");

   $twit->credentials("otheruser", "otherpass");

   $result = $twit->update("Status for otheruser");

DESCRIPTION

http://www.twitter.com provides a web 2.0 type of ubiquitous presence. This module allows you to set your status, as well as the statuses of your friends.

You can view the latest status of Net::Twitter on it's own twitter timeline at http://twitter.com/net_twitter

INTERFACE

new(...)

You must supply a hash containing the configuration for the connection.

Valid configuration items are:

username

Username of your account at twitter.com. This is usually your email address. REQUIRED.

password

Password of your account at twitter.com. REQUIRED.

useragent

OPTIONAL: Sets the User Agent header in the HTTP request. If omitted, this will default to "Net::Twitter/$Net::Twitter::Version (Perl)"

source

OPTIONAL: Sets the source name, so messages will appear as "from <source>" instead of "from web". Defaults to displaying "Perl Net::Twitter". Note: see Twitter FAQ, your client source needs to be included at twitter manually.

This value will be a code which is assigned to you by Twitter. For example, the default value is "twitterpm", which causes Twitter to display the "from Perl Net::Twitter" in your timeline.

Twitter claims that specifying a nonexistant code will cause the system to default to "from web". Some testing with invalid source codes has caused certain requests to fail, returning undef. If you don't have a code from twitter, don't set one.

clientname

OPTIONAL: Sets the X-Twitter-Client-Name: HTTP Header. If omitted, this defaults to "Perl Net::Twitter"

clientver

OPTIONAL: Sets the X-Twitter-Client-Version: HTTP Header. If omitted, this defaults to the current Net::Twitter version, $Net::Twitter::VERSION.

clienturl

OPTIONAL: Sets the X-Twitter-Client-URL: HTTP Header. If omitted, this defaults to http://x4.net/Net-Twitter/meta.xml. By standard, this file should be in XML format, as at the default location.

apiurl

OPTIONAL. The URL of the API for twitter.com. This defaults to http://twitter.com/ if not set.

apihost
apirealm

OPTIONAL: If you do point to a different URL, you will also need to set apihost and apirealm so that the internal LWP can authenticate.

apihost defaults to www.twitter.com:80.

apirealm defaults to Twitter API.

twittervision

OPTIONAL: If the twittervision argument is passed with a true value, the module will enable use of the http://www.twittervision.com API. If enabled, the show_user method will include relevant location data in its response hashref. Also, the update_twittervision method will allow setting of the current location.

credentials($username, $password, $apihost, $apiurl)

Change the credentials for logging into twitter. This is helpful when managing multiple accounts.

apirealm and apihost are optional and will default to the standard twitter versions if omitted.

CONFIGURATION AND ENVIRONMENT

Net::Twitter uses LWP internally. Any environment variables that LWP supports should be supported by Net::Twitter. I hope.

DEPENDENCIES

LWP::UserAgent
JSON::Any

Starting with version 1.04, Net::Twitter requires JSON::Any instead of a specific JSON handler module. Net::Twitter currently accepts JSON::Any's default order for loading handlers.

HTTP RESPONSE CODES

The Twitter API attempts to return appropriate HTTP status codes for every request.

200 OK: everything went awesome.
304 Not Modified: there was no new data to return.
400 Bad Request: your request is invalid, and we'll return an error message that tells you why. This is the status code returned if you've exceeded the rate limit (see below).
401 Not Authorized: either you need to provide authentication credentials, or the credentials provided aren't valid.
403 Forbidden: we understand your request, but are refusing to fulfill it. An accompanying error message should explain why.
404 Not Found: either you're requesting an invalid URI or the resource in question doesn't exist (ex: no such user).
500 Internal Server Error: we did something wrong. Please post to the group about it and the Twitter team will investigate.
502 Bad Gateway: returned if Twitter is down or being upgraded.
503 Service Unavailable: the Twitter servers are up, but are overloaded with requests. Try again later.

You can view the HTTP code and message returned after each request with the http_code and http_message functions.

TWITTER SOURCES

All tweets are set with a source, so that setting your status from the web interface would display as "from web", and through an instant messenger would show "from im".

It is possible to request a source entry from Twitter which will allow your tweets to show as "from YourWidget".

Beginning in Net::Twitter 1.07 you may set this source by passing the source parameter to the new constructor. See above.

Because of this, all statuses set through Net::Twitter 1.07 and above will now show as "from Perl Net::Twitter" instead of "from web".

For more information, see "How do I get "from [my_application]" appended to updates sent from my API application?" at:

http://groups.google.com/group/twitter-development-talk/web/api-documentation

TWITTER TERMINOLOGY CHANGES

As of July 19th, 2007, the Twitter team has implemented a change in the terminology used for friends and followers to alleviate confusion.

Details of the change are at:

http://twitter.com/blog/2007/07/friends-followers-and-notifications.html

As there are probable changes to the Twitter API in the future, the Net::Twitter API has been enhanced to use the new terminology.

People who follow you are still "followers". People you follow are now "following".

It is HIGHLY recommended that you use the newer terminology in the Net::Twitter API as indicated. The friends terminology is DEPRECATED, and will begin throwing warnings to that effect in a future revision. It is also possible that it will be removed entirely in a future revision.

INCOMPATIBILITIES

The X-Twitter-Client-Name, X-Twitter-Client-Version, and X-Twitter-Client-URL, headers (See: new) are currently a de facto standard that have not been fully codified and accepted by Twitter.

Though they are expected to be accepted as valid (And optional), they could possibly change in the future.

BUGS AND LIMITATIONS

No bugs have been reported.

Please report any bugs or feature requests to bug-net-twitter@rt.cpan.org, or through the web interface at http://rt.cpan.org.
