Flow to transfer NetSuite customers to Zendesk end-users

I'm working on a flow to transfer NetSuite customers over to Zendesk and make them into end-users, so that we'll have all our customers within our Zendesk instance for easier Zendesk ticket submission with end-user information pre-populated within Zendesk from NetSuite.

Any suggestions from anyone that has hopefully done this before?
