Currently the Authentication API has one resource: the token. The URL for the
token endpoint is https://***.newvoicemedia.com/Auth/connect/token, where *** represents a regional subdomain:
|Region||URL subdomain||Base URL|
The token resource represents an access token. The token consists of a
token_type (always ‘bearer’),
access_token (the token itself - a unique string of characters associated with your client credentials), and
expires_in (the expiry time expressed in seconds - always 7200 which equates to two hours).
You must use the token to authenticate all requests to Vonage Contact Center APIs.
