Methodology for API Integrations in Elixir

The article provides an in-depth look at how to effectively implement API integrations within Elixir applications. It highlights the concept of bounded contexts and suggests creating an abstraction layer to prevent tight coupling with vendor APIs, which allows flexibility if a change in service is needed. Arnett outlines a typical design involving defining how a service will be utilized, wrapping the service API, and connecting the two through an adapter module. This structured approach ensures that application developers can interact with these integration points using consistent application-specific models, regardless of the vendor being used. By using adapter modules, developers can map between their own domain and the vendor's domain, which helps manage complexity and keep the application extensible.
