In the world of modern software development, rest API’s enable seamless communication between systems, services and applications. Specifying REST API calls is equally important for ensuring clarity, functionality, and integration efficiency. Rest APIs provide a way for two applications to communicate, which enables your software to interact efficiently with various other services, thereby enhancing its capabilities and user experience. Rest APIs work by fielding requests for a resource and returning all relevant information about the resource, that is translated into a format that clients can easily interpret. Clients can also modify items on the server and even add new items to the server through a REST API. The six rules of REST APIs include client-server separation. The client sends a request to the server, then the server sends a response back to the client. Servers cannot make requests and clients cannot respond, and all interactions are initiated by the client. The second rule is uniform interface where all requests and all responses must follow a common protocol, or a way of formatting their messages. The third rule is stateless which means that every interaction is independent, and each request provides all the information required to complete the interaction. One important thing we need to understand is why use REST APIs. Rest APIs are flexible where they can handle many types of requests and send data in many different formats. Rest APIs are scalable. They are designed for communication between any two pieces of software, regardless of size.
Benefits of REST APIs help systems and applications communicate with each other. They are simple to use and implement. You can scale REST APIs easily and this is because they are stateless, meaning each request from a client has all the information your server will need to fulfil it. There are a few different types of APIs. One is private APIs.These are internal to an enterprise and only used for connecting systems and data within the business.Public APIs
These are open to the public and may be used by anyone. There may or not be some authorization and cost associated with these types of APIs. Partner APIs.These are only accessible by authorized external developers to aid business-to-business partnerships. Composite APIs. These combine two or more different APIs to address complex system requirements or behaviors. Some of the steps to create an API are plan the API, build the API, test the API, document the API, and then market the API. I chose these resources because they explain REST APIs in more detail and how they are used in the real world.
