+On the server-side, the <PlatformLink to="/configuration/integrations/requestdata/">RequestData Integration</PlatformLink> captures incoming request data including cookies, headers, query strings, request body (`data`), URL, and user information. By default, most of these fields are captured (except IP address).

 ## Response Body
 
 By default, the Sentry SDK doesn't send the body content of responses received from outgoing requests. By default, the SDK will send the response body size based on the `content-length` header.

+<Alert level="warning" title="Upcoming Changes in v11">
+
+In version 11, the default behavior of the RequestData integration will likely change to be more privacy-conscious. Fields like `cookies`, `data`, `headers`, `query_string`, and `user` will default to `false` instead of `true`. To continue capturing this data after upgrading to v11, you'll need to either explicitly configure the <PlatformLink to="/configuration/integrations/requestdata/">RequestData Integration</PlatformLink> or set <PlatformLink to="/configuration/options/#sendDefaultPii">`sendDefaultPii: true`</PlatformLink>.
