public void setEndpointType(String endpointType) {
        this.endpointType = endpointType;
    }
<p>
The endpoint type. Valid endpoint types include:
</p>
<ul>
<li>
<p>
<code>iot:Data</code> - Returns a VeriSign signed data endpoint.
</p>
</li>
</ul>
<ul>
<li>
<p>
<code>iot:Data-ATS</code> - Returns an ATS signed data endpoint.
</p>
</li>
</ul>
<ul>
<li>
<p>
<code>iot:CredentialProvider</code> - Returns an IoT credentials provider API endpoint.
</p>
</li>
</ul>
<ul>
<li>
<p>
<code>iot:Jobs</code> - Returns an IoT device management Jobs API endpoint.
</p>
</li>
</ul>
<p>
We strongly recommend that customers use the newer <code>iot:Data-ATS</code> endpoint type to avoid issues
related to the widespread distrust of Symantec certificate authorities. ATS Signed Certificates are more secure
and are trusted by most popular browsers.
