# Design the user experience

What should your integration's user interface look like? What design elements should you include? This section describes the design elements that we recommend you include in your integration.

As previously stated, these elements aren’t required for marketplace integrations; they’re only suggestions. These elements are meant to help you create an integration that’s straightforward and uncomplicated for your users.
