agreeD is an innovative platform designed to redefine contract management through a hybrid approach. While many solutions focus on fully autonomous systems, agreeD emphasizes collaboration between cutting-edge AI and human decision-making. By blending automation with real-time assistance and user-focused design, agreeD empowers users to streamline contract workflows without compromising the nuanced judgment needed in legal agreements.

This guide will help you set up the backend for agreeD, built on Node.js with a server.js entry point. As the application is not hosted, you will need to configure environment variables and manually obtain API keys for integrations.

1. Node.js: Ensure that Node.js is installed on your machine. Download Node.js
2. npm or yarn: Comes with Node.js; check by running npm -v or yarn -v.
3. MongoDB: A MongoDB cluster is required. Set up a cluster on MongoDB Atlas or host MongoDB locally.

Create a .env file in the root directory of the project and add the following variables:

JWT_SECRET=your_jwt_secret
PORT=3000
MONGO_URI=your_mongo_connection_string
SESSION_SECRET=your_session_secret

# Google OAuth

# Google Credentials
GOOGLE_CREDENTIALS={"type":"service_account","project_id":"your_project_id","private_key_id":"your_private_key_id","private_key":"your_private_key","client_email":"your_client_email","client_id":"your_client_id","auth_uri":"https://accounts.google.com/o/oauth2/auth","token_uri":"https://oauth2.googleapis.com/token","auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs","client_x509_cert_url":"your_client_x509_cert_url"}

Replace the placeholder values with your actual API keys and secrets. Keep this file secure and never expose it in public repositories.

1. Visit the Google Cloud Console.
2. Create a new project and enable the Google+ API and OAuth 2.0.
3. Create credentials for a web application.
4. Add http://localhost:3000 as the redirect URI.
5. Copy the Client ID and Client Secret.

1. Sign up for a DocuSign Developer Account.
2. Create an integration key under Apps and Keys.
3. Add a redirect URI and download the private key.

1. Sign up for a Twilio Account.
2. Navigate to the Console Dashboard to obtain your Account SID, Auth Token, and phone number.
3. Since we are using a testing account for Twilio, you can test the account using the phone number +918168824369.

1. Create a Stripe Account.
2. Get the Secret Key and Webhook Secret from the Developers section.

1. Follow the steps to obtain your Gemini API Key on their developer portal.
