📘 Description
This workflow is a fully automated contract generation and delivery system that converts structured client input into a finalized, professional PDF contract and uploads it directly to your CRM. It eliminates manual document handling by dynamically populating a Google Docs template, exporting it as a PDF, and delivering it to GoHighLevel in a single flow, while ensuring no temporary files remain in storage.

⚙️ Step-by-Step Flow
Receive Contract Request (Webhook)
Accepts a POST request containing all contract data:
Client name
Date
Scope of works (array)
PC items (array)
Financials (subtotal, GST, total)
Copy Master Template (Google Drive)
Creates a duplicate of the master contract template.
Ensures the original template remains unchanged.
Populate Contract with Client Data (Google Docs)

Replaces placeholders with dynamic client inputs

Updates totals and metadata
Download Contract as PDF (Google Drive)
Exports the fully populated document as a PDF file.
Upload PDF to GoHighLevel (HTTP Request)
