True or False: A RESTful API can only be accessed over the HTTPS protocol.

A RESTful API is not limited to being accessed solely over the HTTPS protocol. While HTTPS is the preferred and more secure option for communication with APIs because it encrypts data during transmission, RESTful APIs can also be accessed over HTTP, which does not provide the same level of security.

The flexibility in protocol usage allows developers to choose the most appropriate method based on their specific needs, which could include using plain HTTP in development environments or for public APIs where sensitive data is not being transmitted. However, in production settings, especially where security is a concern, HTTPS is highly recommended.

This understanding is crucial for managing API interactions, as it influences decisions around security measures, network configurations, and best practices in application development.
