Describe the concepts of RESTful API principles.
- The principles followed by RESTful APIs include statelessness, uniform interface, and resource-oriented architecture.
- In statelessness, in every request of a client to a server, there are all needed information for understanding this request in order to deliver it properly for promotion of simplicity and scalability.
- Engineer is a tool dedicated to solving problems by developing strategies and implementing solutions. Uniform Interface dictates how a resource is called for and used through the conventional http methods like āGETā, āPOSTā, āPUTā and delete.
- Resource-based architecture centers around resource (entity or service), indicated with its unique URI, focusing on simplified and scalable design.
- The use of standard HTTP protocols in creating RESTful APIs means that they can easily be implemented since they are compatible with many applications.
