Set Up User Feedback

When a user experiences an error, Sentry provides the ability to collect additional feedback. You can collect feedback according to the method supported by the SDK.

Use the .NET SDK

You can create a form to collect the user input in your preferred framework, and use the SDK's API to send the information to Sentry. You can also use the widget, as described below. If you'd prefer an alternative to the widget or do not have a JavaScript frontend, you can use this API:

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

SentrySdk.CaptureUserFeedback(eventId, "user@example.com", "It broke.", "The User");

Crash-Report Modal

Our embeddable, JavaScript-based, Crash-Report modal is useful when you would typically render a plain error page (the classic 500.html) on your website.

To collect feedback, the Crash-Report modal 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 Crash-Report modal, though yours may differ depending on your customization:

Integration

The modal authenticates with your public DSN, then passes in the Event ID that was generated on your backend.

Make sure you've got the JavaScript SDK available:

<script
  src="https://browser.sentry-cdn.com/8.38.0/bundle.min.js"
  integrity="sha384-48iagrZwMa6wkDoJKNyCk4jgMHcOcsBK/DzZAJInl1ZhtunellJDCRNZuomfHefF"
  crossorigin="anonymous"
></script>

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

@using Sentry
@using Sentry.AspNetCore
@inject Microsoft.Extensions.Options.IOptions<SentryAspNetCoreOptions> SentryOptions

@if (SentrySdk.LastEventId != SentryId.Empty) {
  <script>
    Sentry.init({ dsn: "@(SentryOptions.Value.Dsn)" });
    Sentry.showReportDialog({ eventId: "@SentrySdk.LastEventId" });
  </script>
}
