What are the advantages of header versioning in APIs?

What are the advantages of header versioning in APIs?

Header versioning allows for more flexibility in API design. It enables clients to specify which version they want to use without changing the URL.

Can you explain how it improves backward compatibility?

Sure! By using header versioning, you can introduce new features in a new version while still supporting older clients that rely on the previous version.

Are there any downsides to using header versioning?

One downside is that it can complicate the API design and documentation, making it harder for developers to understand which headers to use.

How does it compare to URL versioning?

URL versioning is more straightforward but can lead to a proliferation of endpoints. Header versioning keeps the URL clean and allows for more granular control.

What best practices should I follow when implementing header versioning?

Best practices include clearly documenting the versioning scheme, ensuring consistent header usage, and providing a deprecation policy for older versions.
