GoHighLevel API integration for a Next.js SaaS website

I run a SaaS product with a Next.js website and need it connected to GoHighLevel (GHL). What needs to be built: - Website forms (signup, demo request, contact) create and update contacts in GHL through the API - New signups and form submissions trigger GHL workflows and move contacts through pipeline stages - Webhooks from GHL sync data back to the app (contact status, appointments) - Secure authentication (OAuth or API key handling), plus error handling and retries so no lead is lost - Short handover documentation Stack: Next.js (App Router), TypeScript, GHL API v2, webhooks. Deliverables: 1. Forms syncing contacts to GHL 2. Workflows and pipeline stages triggered from the app 3. Two-way webhook sync 4. Secure auth, error handling and retries 5. Handover documentation You are a good fit if you: - Have shipped GHL API integrations with a Next.js or React front end - Write clean, production-ready TypeScript and can explain your decisions - Communicate clearly and work independently To apply: start your proposal with one GHL integration you built, with a link or a short description. Generic proposals will be skipped.
