You should think about API versioning when you're planning changes that could break existing applications.

hey folks, ive been thinking about API versioning lately, especially as our services grow and evolve. weve managed without it for a while, but im starting to see situations where we might need it to avoid breaking existing clients. what are your thoughts on when to introduce versioning? do you go with url versioning, accept headers, or something else? what are the pros and cons youve seen in practice?
