Creating Customer while creating Subscription

Summary:

We are pushing subscription from EBS to Subscription cloud. Can we do this as follows:

if the customer is not there, it will first create the customer in subscription cloud and then

create the Subscription

What is the API for creating customer in subscription cloud for this?

Appreciate any input
