<p>Authentication for the Twitter API</p>
<p>Earlier versions of this node provided one-click authentication. Twitter removed the ability
to do that in June 2018. You must now register your own application with
<a href="https://apps.twitter.com">Twitter</a> and generate your own access tokens.</p>

<p>Twitter input node. Can be used to search either:
<ul><li>the public stream for tweets containing the configured search term</li>
<li>all the tweets from accounts that the authenticated user follows</li>
<li>all tweets by specified users</li>
<li>tweets from accounts that the authenticated user follows</li>
<li>tweets by specified users</li>
<li>direct messages received by the authenticated user</li>
</ul></p>
<p>Use space for <i>and</i> and comma , for <i>or</i> when searching for multiple terms.
If you want to pass in the search term(s) via the <code>msg.payload</code>, leave the <b>for</b> field blank.</p>
<p>Sets the <code>msg.topic</code> to <i>tweets/</i> and then appends the senders screen name.</p>
<p>Sets <code>msg.location</code> to the tweeters location if known.</p>
<p>When returning events it sets the <code>msg.payload</code> to the twitter event, a full list is documented by
<a href="https://dev.twitter.com/streaming/overview/messages-types#Events_event" target="_new">Twitter</a>.</p>
<p>Sets <code>msg.tweet</code> to the full tweet object as documented by <a href="https://dev.twitter.com/overview/api/tweets" target="_new">Twitter</a>.
<p><b>Note</b>: This node is not connected to the FireHose, so will not return 100% of all tweets to a busy @id or #hashtag.</p>
<p><b>Note:</b> when set to follow specific users, or your direct messages, the node is subject to
the rate limiting of the Twitter API. If you deploy the flows multiple times within a 15 minute window, you may
exceed the limit and will see errors from the node. These errors will clear automatically when the current 15
minute window passes.</p>
<h3>Outputs</h3>
<dl class="message-properties">
<dt>payload <span class="property-type">string</span></dt>
<dd>the text of the tweet</dd>
<dt>topic <span class="property-type">string</span></dt>
<dd>set to <code>tweets/<i>screen_name</i></code></dd>
<dt>tweet <span class="property-type">object</span></dt>
<dd>the full tweet object returned by the Twitter API</dd>
<dt>location <span class="property-type">object</span></dt>
<dd>location information associated with the tweet, if known</dd>
</dl>
<h3>Details</h3>
<p>When searching for multiple terms, use a space for <i>and</i> and comma `,` for <i>or</i>.
<p>The full tweet object is documented <a href="https://developer.twitter.com/en/docs/tweets/data-dictionary/overview/tweet-object" target="_new">here</a>.</p>
<p><b>Note:</b> this node is subject to the rate limiting restrictions of the Twitter
API. It polls the API once a minute for updates. If you deploy frequently you may
exceed the limit. The node will automatically delay polling until the end of the current
rate limiting window.</p>
