Clay Integration Guide

Use the Hillwinds API with Clay to enrich company and contact records in your prospecting workflows.

Setup

  1. In Clay, add an HTTP API enrichment step
  2. Set the method to GET
  3. Set the URL to: https://api.hillwinds.ai/v1/companies/lookup?domain={{company_domain}}
  4. Add header: Authorization: Bearer ss_live_YOUR_KEY_HERE
  5. Enable flat mode for easier column mapping — append &format=flat to the URL

Company enrichment by domain

bash
GET https://api.hillwinds.ai/v1/companies/lookup?domain={{company_domain}}&mode=full&format=flat

This returns a single flat row with all company fields as simple key-value pairs — ready for Clay column mapping.

Contact enrichment

After enriching the company, pull contacts:

bash
GET https://api.hillwinds.ai/v1/personnel?lead_type=company&company_eins={{enriched_ein}}&seniority=C-suite,VP-Director&has_email=true&format=flat&page_size=5

Building a prospecting list

Use the list endpoint with filters to build a targeted list directly:

bash
GET https://api.hillwinds.ai/v1/companies?states=CA,NY&industries=Hospitals&employee_bands=Mid-market+Accounts&signals=carrier_change&format=flat&mode=full&page_size=100

Tips

  • Use format=flat for all Clay requests — it eliminates nested objects
  • Use mode=basic to save credits when you don't need relationship data
  • Use eb[website]=true to skip companies without websites
  • Lookup endpoints (/lookup?domain=) are best for single-record enrichment
  • List endpoints are best for building prospecting lists
