"content": "## Enrich Form Leads with Lusha and Waterfall Fallback Provider\n\n**Who it's for:** Growth & Ops teams who need maximum data coverage\n\n**What it does:** Enriches form leads first with Lusha, then calls a fallback provider only if key fields (email or phone) are missing. Merged data is synced to HubSpot and an SDR is alerted on Slack. Reduces costs while maximizing coverage.\n\n### How it works\n1. Receives form submission via webhook and validates the email\n2. Enriches with Lusha (primary provider)\n3. If email or phone is missing \u2192 calls a fallback HTTP enrichment provider\n4. Merges all data from both sources into one clean record\n5. Creates/updates HubSpot contact and notifies SDR on Slack\n6. Returns the enriched record to the form\n\n### Setup\n1. Install the [Lusha community node](https://www.npmjs.com/package/@lusha-org/n8n-nodes-lusha)\n2. Add your Lusha API, HubSpot OAuth2, and Slack credentials\n3. Configure the fallback HTTP node with your secondary provider's API endpoint and key\n4. Point your form's action URL to the webhook endpoint"
