# Applications

The `Application` resource represents your app. For example, an iOS app, website, online marketplace, SaaS platform, etc. – any web service that connects buyers (i.e. customers) and sellers (i.e. merchants). In other words, an `Application` is a resource that represents the program you're integrating with Finix and using to connect with customers (i.e. buyers).
