# SRI Reports # {#sri-report}

<dfn>SRI Reports</dfn> indicate that the user agent refused to render or execute a response that failed an integrity check.

<a>SRI Reports</a> are a type of [=report=] and have the <a>report type</a> "sri".

<pre class="idl">
[Exposed=(Window,Worker)]
interface SriReportBody : ReportBody {
[Default] object toJSON();
readonly attribute USVString blockedURL;
readonly attribute DOMString? integrityAttribute;
};
</pre>

: {{blockedURL}}
:: The URL of the resource that failed the integrity check.
: {{integrityAttribute}}
:: The integrity attribute of the element.

<a>SRI Reports</a>, if sent, must be sent to a <a lt="endpoint">reporting endpoint</a> with a name of <code>sri</code> and must only be sent as the result of a failed integrity check and not any other error to ensure that no privacy or security risk is introduced.
