APIs have become so ingrained in our lives that we now say we "access" an API instead of connecting to a web service. One of the cornerstones of such a heavily used technology is versioning. So, when versioning our APIs, should we use URIs or HTTP Headers? This has been a hotly debated topic in developer communities for a long time. Based on my own experiences, let's lay out the pros, cons, and when to choose which approach.
In this post, I will delve deep into API versioning strategies, explaining the advantages and disadvantages of both approaches with concrete examples. My goal is to help developers choos
