Answer:

During my tenure as a software developer at XYZ Corporation, I was responsible for building a mobile application that required the integration of multiple APIs. While working on the project, I faced a technical challenge where the APIs were not returning the expected results. I had to approach the problem systematically to identify the root cause and resolve it.Firstly, I reviewed the API documentation and experimented with different parameters to ensure I was making the correct requests. Later, I used debugging tools, such as Postman and Fiddler, to gather more information about the requests and responses. This allowed me to narrow down the issue to the authentication header not being passed correctly.To resolve this, I collaborated with a colleague who had more expertise in API integrations. We reviewed the authentication protocol and made necessary adjustments in the code. This resulted in passing the authentication token successfully, and the application functioned as intended. In the end, the project was completed on time, and the user feedback was positive. I learned from this experience that in software development, working collaboratively with team members is essential. A team that communicates effectively can approach and solve complex technical problems efficiently, leading to successful project completion. Thorough API documentation review and utilizing debugging tools can help narrow down issues and pinpoint the root cause more quickly.Relevant Citations:
