Flask PayPal Integration

This project demonstrates how to integrate PayPal Checkout with a Flask web application. The application displays a list of products, and when a user selects a product, the PayPal Checkout button allows them to make a purchase.

Getting Started

Prerequisites

• Python 3.x
• Virtualenv

Setting Up

1. Clone the repository:

   https://github.com/Orrv2904/Flask-Paypal-Integration.git
   cd Flask-Paypal-Integration
   code .

2. Create a virtual environment:

   virtualenv venv

   or

    python3 -m venv venv

3. Activate the virtual environment:

   • On Windows:

     venv\Scripts\activate

   • On macOS and Linux:

     source venv/bin/activate

4. Install the requirements:

   pip install -r requirements.txt

Configuration

Replace the placeholder in .env with your own PostgreSQL database connection string:

DATABASE_URL=your_postgresql_connection_string

Running the Application

1. Create tables in the database:

   python -m create

2. Add data to the products table, you can do it from the database manager.

3. Run the application:

   flask run

The application should be running at http://127.0.0.1:5000/.

PayPal Integration

The PayPal integration is implemented in the index.html file. It fetches product information from the server and uses the PayPal SDK to create a checkout button.

Ensure you have a PayPal Sandbox account, and replace client-id in the script tag with your own PayPal client ID.

<script src="https://www.paypal.com/sdk/js?client-id=your_paypal_client_id&currency=USD"></script>

Usage

1. Visit http://127.0.0.1:5000/ in your browser.

2. Select a product to view its details.

3. Click the PayPal Checkout button to initiate the payment process.

4. Complete the payment on the PayPal sandbox.
