API Testing in Spring Boot using Postman | Marketplace Backend Project | Day 5 | DPK Dev Studio

In this video, I test all the REST APIs of my Spring Boot backend project using Postman.

This video covers:
• Testing User APIs (Create, Get, Update, Deactivate)
• Testing Listing APIs (Create, Fetch, Update, Mark as Sold, Delete)
• Validating request and response flow
• Verifying API integration with database
• End-to-end backend API validation

This project is built step by step following clean layered architecture:
Entity → Repository → Service → Controller → API Testing

No UI is involved at this stage.
All APIs are tested using Postman.
