In this talk we will discuss how to apply architecture discipline to the API as a Product concept. To create an API ecosystem, we need to treat every API as a software product which means we need to think beyond API design and consider significant requirements such as security, observability, usability and other -ilities of software. Why are these significant requirements important to consider as early as possible and why it is costly to change after the fact? How can API governance and architecture close the loop and help API producers to deliver high-quality API products?
