Before switching fully to Stripe production, let’s run a final QA—this can still be done in the staging environment if needed. Since our setup now uses only environment variables to switch between local and production, we can confidently test everything locally and expect it to behave the same in production.

Learn how to properly configure environment variables in Vite by prepending them with `VITE_` to ensure your React frontend can access backend URLs correctly across development and production environments.
Discover the importance of mimicking production environments locally before deployment, running your frontend and backend separately helps catch configuration issues early and ensures seamless integration.
Understanding why ngrok URLs must be updated in Stripe webhooks after each restart, and how to edit webhook endpoints to maintain proper communication between your local server and Stripe's payment events.
How to debug API calls using browser network tabs to verify that environment variables correctly prepend API endpoints, ensuring your frontend communicates with the right backend URL in both local and production setups.
