Currently the Authentication API has one resource: the token. The URL for the token endpoint is https://***, where *** represents a regional subdomain:

Region URL subdomain Base URL
EMEA emea
USA nam
APAC apac

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.
