&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;When starting a certification job with [[web/stamp]] you can provide a callback URL.&lt;br /&gt;
&lt;br /&gt;
Once the certification job is finished, the callback URL will receive a POST call with the same JSON object as returned in the [[web/status]] operation.&lt;br /&gt;
&lt;br /&gt;
To authenticate the callback, the JSON object HMAC-SHA1 will be calculated using the API client private key and will be provided as a query string &amp;#039;&amp;#039;&amp;#039;signature&amp;#039;&amp;#039;&amp;#039; parameter.&lt;br /&gt;
&lt;br /&gt;
NOTE: These callbacks are independent from the [[API Overview#API callbacks | API callbacks]] sent to the callback URL associated to your API client.&lt;br /&gt;
&lt;br /&gt;
== Example ==&lt;br /&gt;
&lt;br /&gt;
Line breaks have been included in this example content for legibility, but actual callbacks include the whole JSON in a single line.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
