Python Payment Integration Web App
Budget: $250 – $750 USD
I’m looking for a skilled developer to create a Python-based web application that can accept online payments reliably and securely. The core goal is a clean, well-documented codebase that handles the full payment flow—initiation, gateway hand-off, confirmation, and error handling—without exposing sensitive data.
Key objectives
• Build the web app in Python (Django, Flask, or FastAPI—state your preference and why).
• Integrate at least one mainstream gateway for credit/debit cards and leave the code flexible enough to plug in PayPal or other providers later.
• Design clear endpoints or views for checkout, payment status callbacks/webhooks, and refunds.
• Keep all secrets in environment variables and follow best PCI practices.
• Include unit tests for the payment logic and brief developer-level documentation.
Nice to have
• Pluggable user authentication (email/password and/or social logins) that can be toggled on or off.
• Docker or similar container setup for effortless deployment.
When you respond, outline the stack you’d use, which payment SDK or API you recommend, and a rough timeline for a working prototype plus polish.
