This document discusses using Ecto to integrate with third party services. It describes Ecto's main components like Repo, Schema, Changeset and Query for working with data. It focuses on how Ecto Changesets provide validation of data from external sources before applying changes. The document also notes challenges with integrating a "shitty" third party service that provides no feedback on requests. It provides examples of using Ecto Changesets to validate data of any Ecto type, with or without a database table.
