Each version of the API is fixed in its base functionality and no breaking changes are introduced once the version is published.

New API end points can be released on a version, or extra data can be returned in a version, but no breaking change will be introduced without a new version being released. 

When we launch a new version, we then increase the API number to the new version allowing your existing integrations to continue working.

You can find versions of the API available at:
