Our new API is live!

Our new API is now available to use. We have improved the methods that you are familiar with, offering you a clearer understanding of what each property can do and a more detailed response from each call.

The old API is still fully functioning and support for this will not end.

We are also introducing API Keys which are used to access the API methods and improve the security around using the API.
