I want to see every visitor’s journey flow seamlessly from my WordPress marketing site (galvanizetestprep.com) into the React web app that lives at go.galvanizeme.com and, once there, have that record stay intact inside Zoho SalesIQ and Zoho CRM. At the moment SalesIQ treats the two domains as strangers, so attribution breaks the moment someone clicks “Start Free Trial”. Here is what I need built and verified: • A reliable way to pass the visitor’s email address, once captured, from WordPress to the React app so it becomes the single unique identifier across both domains. • A tracking script (JavaScript, cookies/localStorage) that keeps the session alive and stitches together page views, form submissions, and button clicks no matter where they occur. • Automatic capture of the standard UTM parameters utm_source, utm_medium, and utm_campaign and persistence of those values through the signup flow. • A clean hand-off of the consolidated timeline into Zoho CRM so Sales, Success, and Marketing all see one record that shows ad click → landing page → in-app behaviour. Please lean on Zoho SalesIQ’s visitor API, any server-side helpers you prefer, and best-practice cross-domain cookie handling. Once implemented I will test by sending traffic with known UTM tags; I’ll consider the job complete when I can open a lead in Zoho CRM and watch every event—page views, form submissions, button clicks—stretch across both domains without a gap. If you have shipped something similar with WordPress, React, and Zoho before, I’m all ears for suggestions; I simply need the unified view up and running.
