Yes, type systems get us part the way there, but configuring applications to leverage flexible types from an external system is often an underappreciated, important, task. For instance; it&rsquo;s often the case that, when working with external systems, the onus is on us to make sure the data is prepared in a way that&rsquo;s easy to transmit, but the moment we start sending data, we own the relationship between the two systems. Is the data I&rsquo;m providing accurate to types THEY know about? When I&rsquo;m preparing the request payload, how can I ensure that my data is rolling up to something that will be usable? If I&rsquo;m not sure about which data I&rsquo;m querying at runtime, how can I create an internal contract within my software that expresses the relationship accurately?</p>
