To start using the User Admin API you must have completed the following tasks:

• Sign up for a Vonage Contact Center (VCC) account. Find more information on how to do this at Vonage | Cloud Contact Center.
• Set up a working interaction plan in which interactions are delivered to your agents. For information about setting up interactions plans and using VCC to make and receive interactions, go to /wiki/spaces/PD/pages/40698199.
• Get your client credentials from the VCC Admin Portal, adding the users:read or users:write scope. For information, see Getting API credentials from VCC in How to authenticate with a Vonage Contact Center (VCC) API.
• Use your client credentials to get your bearer access token. You must use your bearer access token to send API requests. The Authentication (User Admin API) section contains information about getting your bearer access token.

The root URL for the User Admin API is https://***.api.newvoicemedia.com/useradmin, where *** represents a regional subdomain. URLs in the example code use *** in place of the region. To access the API for your region, replace *** with the correct subdomain for your region.

Add the resource name to the URL to form the endpoint you need to access the resource and its fields. For example, https://***.api.newvoicemedia.com/useradmin/users provides access to the users resource and its fields.
