# Versioning

Methods in the Web API can change over time, however, despite this, it's important that such a change
does not break older implementations. In order to be able to do so, Web API 3 uses query string versioning.

### Specifying version

In order to specify a version, you simply have to add another query string parameter, **v** for example, **v=1**.
By default, the version is number is always **1**, so if you want to get the newest version, you have to change it explicitly.

### How methods are updated

Web API methods are updated as follows:

* For small changes that include introduction of new input or output parameters, we keep the version number the same. It's important that you use a JSON parser when consuming the API and avoid any RegEx or similar optimizations.
* For changes that affect the way the method works, we will increase the version number.
