Insurance renewal router GHL → Make.com → external API → GHL

A GoHighLevel workflow webhook, routed through a Make.com-style scenario, out to two real external API round-trips, and back as a GHL v2 contact upsert. Built to show the part of your brief that is pure engineering: idempotency, retry, payload mapping, and the secret boundary, all visible as it runs.

What this is. A faithful simulation of GoHighLevel's webhook and contact contracts. The two external calls (ZIP territory + US holiday calendar) are real, keyless round-trips you can verify. The GHL write-back is rendered as the exact v2 call, not written to a live location. This proves the integration architecture, it is not a GHL account screenshot.
