“A good API doesn’t expose the internal data models or internal logic too much. And the more your clients are not under your control, the less you want to do that." Daniel Luebke is a software architect and the co-author of “Patterns for API Design”. In this episode, we discussed some API design patterns and best practices taken from his book. Daniel first shared the importance of understanding domain requirements for building APIs and several API and message best practices, such as API first design, how to design loosely coupled message exchanges, the tradeoff between generic and specialized API operations, and the risk of exposing too much internal data model and logic in our APIs. Daniel also introduced the microservices domain-specific languages (MSDL) as an alternative to Open API for specifying APIs independent of the technology implementation. Towards the end, Daniel explained the importance of defining the API lifecycle, how to support backward compatibility, and the different API versioning strat
