SDK should provide convenient methods for client applications to easily record 
users&#39; behaviors in Apache PredictionIO&#39;s Event Server and also query 
recommendations from the ML Engines. Therefore, a SDK typically has 2 corres
 ponding clients: <code>Event Client</code> and <code>Engine 
Client</code>.</p><p>The following guideline bases on the REST API provided by 
Apache PredictionIO&#39;s Event Client which details can be found <a 
href="http://predictionio.apache.org/datacollection/eventapi/";>here</a>.</p><h2 
id='event-client' class='header-anchors'>Event Client</h2><p>Because the Event 
Server has only 1 connection point, the <code>Event Client</code> needs to 
implement this core request first. The core request has the following 
rules.</p> <ul> <li><p><strong>URL</strong>: <code>&lt;base 
URL&gt;/events.json?accessKey=&lt;your access key&gt;</code> (e.g. <a 
href="http://localhost:7070/events.json?accessKey=1234567890";>http://localhost:7070/events.json?accessKey=1234567890</a>)</p></li>
 <li><p><strong>Request</strong>: <code>POST</code> + JSON data. Please refer 
to the <a href="http://predictionio.apache.org/datacollection/eventapi/";>Event 
Creation API</a> for the details on the fields of the JSON data obje
 ct.</p></li> <li><p><strong>Response</strong>:</p> <ul> 
<li><strong>Success</strong>: status code <code>201</code> with a JSON result 
containing the <code>eventId</code>.</li> <li><strong>Failure</strong>: a JSON 
result containing a <code>message</code> field describing the error. <ul> 
<li>Status code <code>401</code>: invalid access key.</li> <li>Status code 
<code>400</code>: fail to parse the JSON request e.g. missing required fields 
like <code>event</code>, or invalid <code>eventTime</code> format.</li> 
</ul></li> </ul></li> </ul> <p>Other convenient methods are just shortcut. They 
could simply build the event&#39;s parameters and call the core request. 
<code>Event Client</code> should support the following 7 shorthand 
operations:</p> <ul> <li><p><strong>User entities</strong></p> <ul> 
<li><p><strong>Sets properties of a user</strong>: with the JSON object</p><div

SDK should provide convenient methods for client applications to easily record 
users&#39; behaviors in Apache PredictionIO&#39;s Event Server and also query 
recommendations from machine learning Engines. Therefore, a SDK typically has 2
  corresponding clients: <code>Event Client</code> and <code>Engine 
Client</code>.</p><p>The following guideline bases on the REST API provided by 
Apache PredictionIO&#39;s Event Client which details can be found <a 
href="http://predictionio.apache.org/datacollection/eventapi/";>here</a>.</p><h2 
id='event-client' class='header-anchors'>Event Client</h2><p>Because the Event 
Server has only 1 connection point, the <code>Event Client</code> needs to 
implement this core request first. The core request has the following 
rules.</p> <ul> <li><p><strong>URL</strong>: <code>&lt;base 
URL&gt;/events.json?accessKey=&lt;your access key&gt;</code> (e.g. <a 
href="http://localhost:7070/events.json?accessKey=1234567890";>http://localhost:7070/events.json?accessKey=1234567890</a>)</p></li>
 <li><p><strong>Request</strong>: <code>POST</code> + JSON data. Please refer 
to the <a href="http://predictionio.apache.org/datacollection/eventapi/";>Event 
Creation API</a> for the details on the fields of the JSON da
 ta object.</p></li> <li><p><strong>Response</strong>:</p> <ul> 
<li><strong>Success</strong>: status code <code>201</code> with a JSON result 
containing the <code>eventId</code>.</li> <li><strong>Failure</strong>: a JSON 
result containing a <code>message</code> field describing the error. <ul> 
<li>Status code <code>401</code>: invalid access key.</li> <li>Status code 
<code>400</code>: fail to parse the JSON request e.g. missing required fields 
like <code>event</code>, or invalid <code>eventTime</code> format.</li> 
</ul></li> </ul></li> </ul> <p>Other convenient methods are just shortcut. They 
could simply build the event&#39;s parameters and call the core request. 
<code>Event Client</code> should support the following 7 shorthand 
operations:</p> <ul> <li><p><strong>User entities</strong></p> <ul> 
<li><p><strong>Sets properties of a user</strong>: with the JSON object</p><div

sites or software through their webhooks services (for example, SegmentIO, 
MailChimp). To support that, a <em>Webhooks Connector</em> for the third-party 
data is needed to be integrated into Event Server. The job of the <em>Webhooks 
Connector</em> is as simply as converting the third-party data into Event JSON. 
You can find an example below.</p><p>Currently we support two types of 
connectors: <code>JsonConnector</code> and <code>FormConnector</code>, which is 
responsible for accepting <em>JSON</em> data and <em>Form-submission</em> data, 
respectively.</p><p><strong>JsonConnector</strong>:</p><div class="highlight

sites or software through their webhooks services (for example, SegmentIO, 
MailChimp). To support that, a <em>Webhooks Connector</em> for the third-party 
data is needed to be integrated into Event Server. The job of the <em>Webhooks 
Connector</em> is as simply as converting the third-party data into Event JSON. 
You can find an example below.</p><p>Currently we support two types of 
connectors: <code>JsonConnector</code> and <code>FormConnector</code>, which is 
responsible for accepting <em>JSON</em> data and <em>Form-submission</em> data, 
respectively.</p><p><strong>JsonConnector</strong>:</p><div class="highlight

 </pre></td></tr></tbody></table> </div> <p>Note that the name of the 
connectors (e.g. &quot;examplejson&quot;, &quot;segmentio&quot;) will be used 
as the webhooks URL. In this example, the event server URL to collect data from 
&quot;ExampleJson&quot; would be:</p><div class="highlight shell"><table 
style="border-spacing: 0"><tbody><tr><td class="gutter gl" style="text-align:

class="o">=</span>&lt;CHANNEL_NAME&gt;
 </pre></td></tr></tbody></table> </div> <p>For <code>FormConnector</code>, the 
URL doesn&#39;t have <code>.json</code>. For example,</p><div class="highlight 
shell"><table style="border-spacing: 0"><tbody><tr><td class="gutter gl" 
style="text-align: right"><pre class="lineno">1</pre></td><td

Apache PredictionIO, you can send the ExampleJson data to the following URL and 
the data will be stored to the App of the corresponding Access 
Key.</p></div></div></div></div><footer><div class="container"><div
