How to build a DocuSign file archive extension

In a previous article, I shared how to reach 1.5 million paying customers with a DocuSign extension. Here’s a real-world example: a lightweight integration that archives signed contract details into Notion. Learn how it works and access the code to build your own DocuSign extension.

The article how to reach 1.5 million paying customers with a DocuSign extension explores opportunities for creating extensions within the DocuSign ecosystem. As a follow-up, this article provides a real-world example: a lightweight integration that archives signed contract details into Notion.
 
This example demonstrates how to build a simple tool that solves a specific pain point while working within DocuSign’s platform constraints. The code for the integration is available here: GitHub Repo.

What the Integration Does

The app automatically sends signed envelope metadata and links from DocuSign to a Notion database. Users duplicate a prebuilt Notion database template, and the app handles the rest. It simplifies contract tracking and keeps everything organized in one place.

How It Works

The app authenticates with DocuSign using OAuth to access contract data securely. It sends details like envelope status and document links to the Notion database. The app is built with Flask, Supabase, and Python, making it lightweight and accessible for developers or small teams to use and modify.

Ideas for Expansion

This integration can be expanded in several ways to address additional use cases:
  • Store signed documents in S3 and link them to Notion for easier access.
  • Add two-way data syncing between DocuSign and Notion to create a more dynamic workflow.
  • Use DocuSign’s storage location functionality to improve how files are managed and shared.

Check Out the Code

The full source code for this example is available here: GitHub Repo. You can use it as a starting point for your projects or customize it to meet your needs. If you build something new with it, I’d love to hear about it.
