REST API services made easy!

REST APIs have now evolved as the commonest modes to help connect components in the architectures of microservices. It offers flexibility along with the lightweight way in terms of integrating with the applications.

What is a REST API?

API or application programming interface is considered as a set of rules defining the way applications or devices are connecting to or are communicating with each other. REST API is considered as an API conforming to the designing principles along with the representational state of the transfer of the architectural styles. It is for this reason, and these are at times referred to the RESTful APIs.

The design principles

We are offering Custom API Development using the frameworks of Laravel as well as Codeignitor. We consider the API as the mechanism enabling an application or the services to access a resource within the other application or even the service at the most basic level. The client is the application or the service that is assessing here with the application or service that contains the resource that is known as the server.
There are a few APIs that impose a strict framework on the developers. But REST APIs can be quite developed, making use of the virtual programming languages, thereby supporting various formats of data. The only requirement here would be in aligning to the following of the six REST design principles that are also considered as the constraints:

  1. Uniform interface

    Irrespective of where the request here is arriving from, all the API requests for similar resources should be looking the same. The REST API should be making sure of the same piece of data, including the name or even the email address of its users belonging to a single resource identifier. These resources should not be very large and should contain every piece of information that would be required by the client.

  2. Client-server decoupling

    In the design of the REST API, the server along with the client applications should be completely independent of each other. The only set of information that the client application should know is the URL of the requested resource as it cannot interact with the server application in any other way.

  3. Statelessness

    The REST APIs mean that every request needs to include all the information that is necessary for terms of processing it as they are stateless. It does not need any kind of server-side sessions, in other words. The server applications here are not allowed of being storing any kind of data that is related to the request of the client.

  4. Cacheability

    The resources should be cacheable on the side of the client or the server. The responses of the server also need to contain information on whether or not caching would be allowed for the resources that are delivered.

  5. Layered system architecture

    The responses, along with the calls, would be going through several different layers in the REST APIs. You should not be assuming that the applications of the clients and servers are connecting directly with each other as there would be a number of intermediaries in the loop of communication.

How REST APIs work

It is through the HTTPS requests is how the REST APIs would be communicating in order to perform the functions that are of the standard database in terms of creating, updating as well as deleting the records that are within these resources. For instance, a REST API would be getting the request in terms of retrieving the record or any other requests in order. The API calls will be used every HTTP method as they are designed pretty well that is similar to a website that is operating in a web browser having the built-in functionality of HTTP. Resource representation is considered as the state of the resource at any specific instant or even the timestamp. It is this information that will be delivered to the client virtually in any format since it is considered to be readable by both machines as well as humans since it is the programming language.
For REST API, the parameters along with the request headers are considered to be quite vital since they would include all the vital identifier information, including the authorizations, uniform identifiers, and many more. A well-designed REST API would make use of the response as well as the request headers along with the modern HTTP status codes.
