User Feedback

Use the .NET SDK

When a user experiences an error, Sentry provides the ability to collect additional feedback. You can create a form to collect the user input in your prefered framework, and use the SDK's API to send the information to Sentry.

using Sentry;

var eventId = SentrySdk.CaptureMessage("An event that will receive user feedback.");

SentrySdk.CaptureUserFeedback(eventId, "", "It broke.", "The User");

On the Web

On a website, this type of feedback is useful when you may typically render a plain error page (the classic 500.html).

To collect feedback, use the embeddable JavaScript widget, which requests and collects the user's name, email address, and a description of what occurred. When feedback is provided, Sentry pairs the feedback with the original event, giving you additional insights into issues.

The screenshot below provides an example of the User Feedback widget, though yours may differ depending on your customization:

To integrate the widget, you'll need to be running version 2.1 or newer of our JavaScript SDK. The widget authenticates with your public DSN, then passes in the Event ID that was generated on your backend.

If you'd prefer an alternative to the widget or do not have a JavaScript frontend, you can use the .NET API mentioned above, or a Web API.

Make sure you've got the JavaScript SDK available:


If you are rendering the page from the server, for example on ASP.NET MVC, the Error.cshtml razor page can be:

@if (SentrySdk.LastEventId != Sentry.Protocol.SentryId.Empty) {
    Sentry.init({ dsn: "examplePublicKey" });
    Sentry.showReportDialog({ eventId: "@SentrySdk.LastEventId" });

Customizing the Widget

You can customize the widget to your organization's needs, especially for localization purposes. All options can be passed through the showReportDialog call.
