API for Assets

API for Assets

I am looking at using the API to add and update Assets within SERVICEDESK plus,
I have looked at the REST API and can use the CMDB to add a CI but when I do I cant see it via the Assets tab. Do I need to do anything additional to see it across both?

I can see I can use the servlet API but this is no longer supported so I cant find any documentation on this.

What is the best way for me to get around this.
