How do I keep multiple API versions?

As often as not, the way teams manage to support multiple versions of an API is by having some form of versioning scheme (most commonly it’s baked into the URL or in the HTTP Headers though in some cases it’s also dynamically assigned) and maintaining multiple codepaths, endpoints and/or shims for different …

How do I handle different API versions?

There are four common ways to version a REST API.

1. Versioning through URI Path.
2. Versioning through query parameters.
3. Versioning through custom headers.
4. Versioning through content negotiation.

Should APIs be versioned?

APIs only need to be up-versioned when a breaking change is made. Breaking changes include: a change in the format of the response data for one or more calls. a change in the request or response type (i.e. changing an integer to a float)

How do I keep my API backward compatible?

API compatibility tips

1. Never change the behavior of HTTP response codes. You should never change the behavior of HTTP response codes in your API.
2. Never change parameters. Avoid creating a new version of the API when you make only minor changes, as it might be overkill.
3. Version your API.
4. Other API best practices.

How to host multiple versions of API in one code base?

Now change the version from the UI itself as below and notice that the entire swagger definition has been changed to version 2. Once executing, you will get the ex [ected response from version 2 of the API. This is the way to host multiple versions of APIs in a single code base.

Why is it important to version Your REST API?

REST API Versioning. To manage this complexity, version your API. Versioning helps you iterate faster when the needed changes are identified. Change in an API is inevitable as your knowledge and experience of a system improve. Managing the impact of this change can be quite a challenge when it threatens to break existing client integration.

How do you manage the underlying codebase for a versioned API?

Changes that are largely orthogonal to the rest of the codebase: the public API can exist peacefully with the rest of the stack without requiring “excessive” (for whatever definition of of that term you choose to adopt) branching in code I did not find it overly difficult to remove deprecated versions using this model:

Can you keep different versions of the same API?

This article covers a practical scenario of maintaining a single code base with different versions of the same APIs. You want to upgrade your existing API with a new version and some customers can’t accommodate those new APIs.
