Creating web-to-lead forms (CRM-Wix)

Hi

I need to link my contact form on my Six Website to our CRM. I don’t know how to do this. I have the documentation here from my CRM - https://app.pipelinedeals.com/api/docs/web_to_leads

The fields I need are:
First_Name
Last_Name
Position
Company
Phone
Email

Can someone do this for me?
