third-party 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

third-party 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

connectors (e.g. &quot;examplejson&quot;, &quot;segmentio&quot;) will be used

&quot;ExampleJson&quot; would be:</p><div class="highlight shell"><table
