Automation Expert Needed for Make.com Integration with Google Sheets & Signable
Project Overview
I need an experienced automation expert to help finalize my client proposal system, which integrates Google Sheets with Signable for document signing. The core functionality is already built, but I need help with the final connection to automatically email proposals.

Current Setup
Google Apps Script: Custom script that generates client proposals and stores them in Google Drive
Google Sheets: Master database tracking proposals with client details, PDF URLs, and email addresses
Make.com: Partially configured scenario to watch for new proposals and send them via Signable API
Signable: Electronic document signing platform with API access
Specific Requirements
Fix the Make.com HTTP module configuration to properly connect with Signable API
Configure correct authentication for the Signable API endpoint
Ensure proper field mapping from Google Sheets to Signable API request
Set up proper error handling and notifications
Create simple documentation for maintaining the system
Technical Details
The Google Sheets database has proposal information with client emails in column S
PDF proposal URLs are already generated and stored in the spreadsheet
Signable API key is available (will share with selected candidate)
Make.com scenario structure is already built but has configuration errors
Required Skills
Make.com (formerly Integromat) expert with HTTP module experience
Experience with API integrations, particularly REST APIs
Understanding of JSON request formatting and field mapping
Experience with Google Sheets integrations
Knowledge of document signing workflows is a plus
There will be plenty more work available to the selected one, as we are building a bespoke system for an accounting practice linking up individual softwares.
