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.

Embeddable JavaScript Widget

Our embeddable JavaScript widget is useful when you may typically render a plain error page (the classic 500.html) on your website.

To collect feedback, the widget 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:

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

In Rails, being able to serve dynamic (for example, .html.erb) pages in response to errors is required to pass the needed event_id to the JavaScript SDK. Typically, this is done by overwriting the config.exceptions_app setting to point to your own router, and then calling your own controller to handle the error. You can find more detailed instructions for this configuration online or install a gem to handle this for you.

Once you're able to serve dynamic exception pages, you can support user feedback.

Make sure you've got the JavaScript SDK available:


Additionally, you need the template that brings up the dialog:

<% sentry_id = request.env["sentry.error_event_id"] %>
<% if sentry_id.present? %>
  Sentry.init({ dsn: "" });
  Sentry.showReportDialog({ eventId: "<%= sentry_id %>" });
<% end %>

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.
