What I like most about RESTful JSON APIs is how simple and flexible they are. JSON is lightweight and easy to work with, and REST APIs tend to integrate smoothly across different platforms and applications. Review collected by and hosted on G2.com.

One drawback of RESTful JSON APIs is that working with complex or very large response payloads can sometimes be inefficient. On top of that, keeping API versions compatible over time can be challenging. Review collected by and hosted on G2.com.
