What are the key differences between REST and SOAP web services, and in what scenarios would you choose one over the other?

In my final year, I worked on a college project that involved creating a web application for managing student records. We chose to use RESTful web services because of their simplicity and ease of integration with our front-end framework. By using REST, we could easily perform CRUD operations, allowing users to create, read, update, and delete student records without the overhead of complex XML parsing required by SOAP. This decision facilitated quicker development cycles, and we were able to provide a smooth user experience with fast loading times, which was essential for our project’s success.

During my time volunteering for a local non-profit, I helped develop a community engagement app. We initially considered SOAP for its security features, but since our app aimed to connect volunteers with opportunities quickly, we opted for RESTful services. This choice allowed us to leverage JSON for data interchange, making it easier for our developers to work with and for users to access information seamlessly. The agility of REST helped us iterate rapidly based on user feedback, resulting in a more effective tool that met the community's needs.

In my internship at a tech startup, I was involved in developing APIs for our new application. We primarily used REST due to its lightweight nature, which was crucial for mobile app performance. However, we also had a need for a SOAP-based service to handle sensitive data transactions, such as payment processing, where security was a top priority. This experience taught me the importance of choosing the right tool for the job, balancing between speed and security based on the application’s requirements.
