The definition is straightforward. The practice of avoiding breaking changes while evolving an API requires engineering discipline that most teams underestimate until they have shipped a breaking change to a production API and experienced the resulting incident response.</p> <p>The instinct to avoid defining something as a breaking change is strong. Removing a field that is not documented is tempting to classify as cleanup rather than a breaking change. Changing an error code from 400 to 422 for a validation failure seems like a trivial semantic correction. Adding a required field to a request body seems like a new feature rather than a breaking change. Each of these reclassifications is wrong, and each produces consumers whose integrations fail after the change.</p>
