Postman API Testing: Catch Backend Bugs Before Production

In this video, we continue building our Document AI application by focusing on one of the most important skills in backend development — testing and debugging. We dive into the essential process of how to debug our project, focusing on identifying and resolving issues from previous sessions. This session is all about practical error handling and utilizing developer tools to ensure our application runs smoothly. 🛠️

This is Part 3 of the series where we build a full stack application from scratch.

In this video we cover:

• Testing APIs using Postman
• Debugging backend issues
• Fixing authentication middleware bugs
• Identifying errors in the summarization workflow
• Improving backend reliability

Tech Stack Used:

* Node.js
* Supabase
* PostgreSQL
* Sequelize ORM
* Postman

Project Demo
client-conceptify.vercel.app/

What you will learn:

✔ How to test APIs properly using Postman
✔ How to debug real backend errors
✔ How to fix authentication issues
✔ How to improve API reliability
✔ How to think like a backend engineer

This video is especially useful if you struggle with debugging Node.js applications.
