Collecting leads via Web To Lead form. (Wufu) How to import to Zoiper 5 CRM?

Question

I see Zoiper 5 Pro has a CRM / contacts list

I see you have CSV importer to Zoiper 5 

But I would like to import from a web data collection (web to lead) form directly into Zoiper 5 Pro

How can my Web to Lead form (I use Wufu) connect to Zoiper?

Is there a Wufu - Zappier - Zopier task?

Where can I read API info?

Also can two people share the same contacts?

Thank you,

Jules
