n8n Webhook Workflow: Sales Calls with GoHighLevel + OpenAI

Turn guided home-service sales calls into synced CRM data—automatically

This n8n Webhook Workflow captures step-based form submissions for a guided home-services sales call, syncs contacts and opportunities to GoHighLevel, calculates a dynamic price range, generates tailored closing phrases with OpenAI, and optionally creates won customers in Housecall Pro—then returns structured JSON to your front end.

What this workflow does

• Receives webhook submissions via a POST request and normalizes the incoming form data into a consistent structure.
• Routes by step_type to handle different parts of the sales call flow (customer info, service selection, pricing, AI closing, and final outcome).
• Creates or updates GoHighLevel contacts for customer_info, mapping customer details and property/service custom fields.
• Guides the next questions for service_selection, including a driveway-size prompt when pressure washing surfaces include a driveway.
• Computes a dynamic price range in pricing_request using service type and property details, then formats it into a display-ready min/max range string.
• Generates closing language with OpenAI for ai_closing, returning 2–3 closing phrases plus brief reasoning parsed into a structured response.
• Finalizes outcomes in GoHighLevel for final_outcome (won/thinking/lost). If won, it also creates the customer in Housecall Pro.
• Returns JSON to the front end so your UI can progress the sales call experience.

Use cases

• A pressure washing or home-services website that runs a guided sales call and needs instant CRM updates in GoHighLevel.
• Automation engineers building an AI-assisted closing flow that calculates quotes and produces call-ready phrases.
• SaaS operators who want end-to-end webhook handling with structured JSON responses.
