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 scala"><table style="border-spacing: 0"><tbody><tr><td class="gutter gl" style="text-align: right"><pre class="lineno">1
