Hybrid TypeForm to CRM Migration Layer

The Problem

A high-volume lead-form operator was running a TypeForm through a fully Zapier-managed chain. The team wanted off Zapier but couldn't rip out the whole chain in one shot because the qualified-lead Slack and Hyros attribution paths were load-bearing. Mixed-platform fragility was the biggest cost. Debugging required opening both n8n and Zapier, and field changes in either system could silently break the contract between them. There was no recovery path for missed partial events.

The Build

I built a transitional 23-node n8n flow that takes ownership of all GoHighLevel contact lookup, custom field updates, and opportunity routing. The TypeForm webhook fires into a Switch that handles qualified, disqualified, and booking events in parallel with a 30-second wait timer for the GoHighLevel contact creation race. The qualified-lead Slack ping and Hyros lead-creation call still POST to external Zapier webhooks for now, which keeps those paths running while the team plans the full migration. Branch-specific opportunity creation matches the 40-node native pattern (qualified gets one stage, disqualified another, booking lands in Call Booked through the Stage Guard), so the cutover later swaps the Zapier-call branches without touching the rest of the architecture.

The Outcome

GoHighLevel contact and opportunity work runs natively in n8n, which means debugging that lane no longer requires opening Zapier. The transitional flow handles live volume daily while the full-native replacement gets staged. The remaining Zapier webhooks are flagged for cutover and the replacement plan is documented in the code: clone the 40-node native, swap form-specific fields, add catch-up plus Stage Guard. The 35-second wait will move to 90 seconds in the cutover to match the GoHighLevel search index delay.
