You have to work on WordPress for API integration and lead capturing and lead tracking.
You can refer the image for lead tracking and lead capturing.
Pollard capturing and tracking details I need these following features like:
contact phone number
location or city
submitted date and time
form title cities
IP original reference and
page referred by
and user agent like Chrome or Mozilla
-- The person must also have a good understanding of API integration and lead capturing and tracking which is more similar to hubspot platform
-- I hope this much of information is enough, but if you want still more information you can text me always on freelance...
