# Your API Returns 200 OK, But the Client Gets the Wrong Result! | Real-World API Debugging

Your API returns **HTTP 200 OK**. Postman shows a successful response. But the client application displays incorrect data.

Where would you start debugging?

In this live technical teaching session, **Sanjay Prakash Pradhan, Microsoft MVP**, explains how to investigate this real-world enterprise application scenario.

A successful HTTP response does not always guarantee a correct business result. The issue could be in backend business logic, JSON serialization, DTO mapping, client-side processing or environment configuration.

### What You Will Learn

- What HTTP 200 OK actually means.
- How to trace the complete API request-response flow.
- How to inspect and validate the actual JSON response.
- How incorrect DTO or client-side mapping creates wrong results.
- Five important production debugging checkpoints.
- How to compare server logs, API responses and client output.
- How to approach API troubleshooting questions in technical interviews.

Real-World Scenario

Imagine an API returns a customer credit limit of 50,000 and available credit of 12,000. But the client application displays 12,000 as the credit limit.

The API may be working correctly. The actual defect could be in client-side property mapping.

Learn how to identify the problem systematically instead of randomly changing code.
