Röll, AchimBonorden, Leif2024-04-082024-04-08https://dl.gi.de/handle/20.500.12116/43835APIs should be stable and demand a careful evolution, which requires a good initial design. Such API design skills usually come from experience, but the API Design Fest intends to compress such experience into a dense course. While the original training event was intended for practitioners, we are interested in the applicability in software engineering education. Thus, we conducted a slightly adopted API Design Fest with students and report on initial insights. While we find the overall event and its API design activities suitable, we recommend extended preparation on breaking changes for future API Design Fests with students.enAPIdesignDesign FesttrainingText/Conference Paper
