Python Payment Processor

This is a simple mock payment processing app I created. It takes POST requests to add payments and returns a URL where that payment can be paid in the response. The data storage mechanism is a simple JSON flatfile.

How to setup and run the application (for unix systems)

1. Install Python 3 on your system
2. Clone this repository
3. In the root of the repository, run the following commands:
   1. Create a virtual environment
      python3 -m venv venv
   2. Activate the virtual environment
      source venv/bin/activate
   3. Install the required packages
      pip install -r requirements.txt
   4. Run the application
      python3 main.py

How to use the application

• Send your POST request to localhost:5000/invoices
• Navigate to the URL in the response
• Enter a payment amount and hit the "Make Payment" button
• Once the you have paid the full amount (or more than the full amount), you will see the "Payment Complete" page
• To reset the stored data, overwrite the data/invoice_data.json with {"invoices": {}}
