HI @splunkusr9,
Have a look at these documents
http://docs.splunk.com/Documentation/SplunkCloud/7.2.0/User/WelcometoSplunkCloud
Splunk API Disabled by default for managed Splunk Cloud deployments. Contact Splunk Support to enable access for managed Splunk Cloud deployments, Splunk Cloud trials, and sandboxes.

To access your Splunk Cloud deployment using the Splunk REST API and SDKs, submit a support case requesting access on the Support Portal. For managed deployments, Splunk Support opens port 8089 for REST access. You can specify a range of IP addresses to control who can access the REST API. For self-service deployments, Splunk Support defines a dedicated user and sends you credentials that enable that user to access the REST API.
