Netlify Form → Salesforce Pardot integration (serverless function)

We use Netlify Forms and need multi-step form submissions forwarded automatically into Salesforce Pardot via a Pardot Form Handler. The approach is already decided — this is a well-defined build, with an eye to reusing the pattern across many landing pages. Scope: A Netlify submission-created function that POSTs verified submissions to our Pardot Form Handler Multi-step form working correctly with Netlify's form detection UTM capture via hidden fields, persisted across the multi-step flow and mapped into Pardot Correct field mapping (our fields → Pardot external field names) Built as a reusable template — form, UTM logic, and mapping in one source of truth, with a clear form-naming convention so new pages work the same way Endpoint stored as an environment variable, plus error handling and logging A test pass confirming submissions land as Prospect activity in Pardot You should have: hands-on Netlify Functions experience, familiarity with Pardot Form Handlers, and solid Node/JavaScript. We'll provide the endpoint URL and field list. Please share a comparable integration and a rough hours estimate.
