+If you do not have access to the `onRequest` middleware API, you can use the `wrapRequestHandler` API instead. For example:
+
+```javascript
+// hooks.server.js
+import * as Sentry from '@sentry/cloudflare';
+
+export const handle = ({ event, resolve }) => {
+  const requestHandlerOptions = {
+    options: {
+      dsn: event.platform.env.SENTRY_DSN,
+      tracesSampleRate: 1.0,
+    },
+    request: event.request,
+    context: event.platform.ctx,
+  };
+  return Sentry.wrapRequestHandler(requestHandlerOptions, () => resolve(event));
+};
+```

 ## Add Readable Stack Traces to Errors
 
 Depending on how you've set up your project, the stack traces in your Sentry errors probably don't look like your actual code.
