## LEGAL BOILERPLATE

<!-- Sentry employees and contractors can delete or ignore this section.

Look, I get it. The entity doing business as "Sentry" was incorporated
in the State of Delaware in 2015 as Functional Software, Inc. and is
gonna need some rights from me in order to utilize my contributions in
this here PR. So here's the deal: I retain all rights, title and
interest in and to my contributions, and by keeping this boilerplate
intact I confirm that Sentry can use, modify, copy, and redistribute my
contributions, under Sentry's choice of terms.

+### Session Replay
+
+The User Feedback widget integrates seamlessly with Session Replay. When the widget is opened, the SDK buffers up to 30 seconds of the user's session. If feedback is submitted, this replay is sent along with the feedback, allowing you to view both the feedback and the user's actions leading up to the feedback submission.

 ## User Feedback API
 
 The user feedback API allows you to collect user feedback while utilizing your own UI. You can use the same programming language you have in your app to send user feedback. In this case, the SDK creates the HTTP request so you don't have to deal with posting data via HTTP.
