The base Fonoa API operates under the below URL for production traffic.
https://api.fonoa.com/ [Endpoint_Category]/vX]
Where X in the base production URL denotes the API version, users can append the version number of the API when accessing resources, such as Fonoa URL. There is one tier of version numbers supported.
Direct version numbers such as 1 will be redirecting the developer to the major Fonoa API version.
