Can you explain the key differences between RESTful and SOAP web services?

During my final year in college, I worked on a project that required building a web application for managing student records. We decided to use RESTful web services because of their ease of use and flexibility. I implemented a REST API that allowed clients to perform CRUD operations using standard HTTP methods. This experience taught me how to handle requests and responses using JSON, making it straightforward to integrate with the front-end. The project helped me understand the key principles of REST, such as statelessness and resource representation, which I could explain clearly during interviews.

In my volunteer role at a non-profit organization, I assisted in developing a system to manage donor information. We opted for SOAP web services to ensure data integrity and security during transactions. I learned how to work with SOAP envelopes and the importance of WS-Security for protecting sensitive information. This hands-on experience allowed me to appreciate the strengths of SOAP, especially in scenarios requiring strict standards and protocols. I could share how this project improved my understanding of web services and their applications in real-world scenarios.

In my first job as a junior developer, I was involved in a project that required integrating third-party services. I had to choose between RESTful and SOAP web services. I led discussions with the team to evaluate the requirements, considering factors like ease of use, performance, and security. Ultimately, we chose RESTful services for their lightweight nature and faster response times, which aligned with our project's goals. This experience helped me develop decision-making skills based on technical requirements, and I learned how to communicate the advantages of each service type to non-technical stakeholders.
