Because API plays a crucial role in this client–server communication, we should always design APIs with best practices in mind. This helps the developers maintaining them, and those consuming them as well, not run into issues while performing those duties. A well-designed API is easy to understand, use, and maintain. It should follow consistent style conventions, include built-in security mechanisms for authentication and data encryption, and reliably handle large volumes of traffic. The most important takeaways for designing high-quality REST APIs is to have consistency by following web standards and conventions. JSON, SSL/TLS, and HTTP status codes are all standard building blocks of the modern web.

You can use REST-based architecture to support high-performing and reliable communication at scale. You can easily implement and modify it, bringing visibility and cross-platform portability to any API system. Testing APIs should always be a part of an API design task and can include API virtualization as a technique. API monitoring helps keep track of API performance and health with analytics-based tools, like APImetrics. API code generation is helpful to quickly convert a design to implementation without risk of errors.
Why use Postman for API design?
Learn how application programming interfaces, or APIs, simplify software development and innovation by enabling applications to exchange data and functionality easily and securely. REST APIs are stateless, meaning that each request needs to include all the information necessary for processing it. In other words, REST APIs do not require any server-side sessions. Server applications aren’t allowed to store any data related to a client request. First, defined in 2000 by computer scientist Dr. Roy Fielding in his doctoral dissertation, REST provides a relatively high level of flexibility, scalability and efficiency for developers. For these reasons, REST APIs have emerged as a common method for connecting components and applications in a microservices architecture.

The only exception is if we’re trying to send and receive files between client and server. Then we need to handle file responses and send form data from client to server. Let's start with integrating some filtering mechanism into our API. We will upgrade our endpoint that sends all workouts by accepting filter parameters.
AddPet.jsx
Normally in a GET request we add the filter criteria as a query parameter. Let's start with the simplest one and return all workouts that are stored and start with implementing the corresponding method inside our Data Access Layer (src/database/Workout.js). In our application we'd like to create, read, update and delete WOD's (Workouts of the Day). This will help our users (that will be gym owners) come up with workout plans and maintain their own workouts inside a single application.
You can store this type of data inside your cache and serve it from there instead of going to the database every time to query the data. All we do here is check if we actually have a truthy value for the key "mode" inside our "filterParams". If this is true, we filter all those workouts that have got the same "mode".
Use Nouns Instead of Verbs in Endpoints
It allows developers to create reusable UI components and efficiently update and render them in response to changes in application state. To ensure the client interprets JSON data correctly, you should set the Content-Type type in the response header to application/json while making the request. RESTful API design is the process of designing an API that follows the principles of Representational State Transfer (REST), which is the most popular API architecture today.

This pet shelter needs to register the pets that are staying in the shelter, and for that we'll perform basic CRUD operations (create, read, update and delete). RESTful APIs are designed to be simple, scalable, and flexible. They are often used in web and mobile applications, as well as in Internet of Things (IoT) and microservices architectures. In simple words, in the REST architectural style, data and functionality are considered resources and are accessed using Uniform Resource Identifiers (URIs). Consider the following REST resource that represents a blog post with links to related resources in an HTTP-based REST API.
Uniform interface
Clients are users who want to access information from the web. The client can be a person or a software system that uses the API. For example, developers can write programs that access weather data from a weather system.
We have to take into account security, performance, and ease of use for API consumers. To move on in our architecture it would be advisable to create another controller, another service, and another collection of database methods that are responsible for records. You can test things out by adding a workout with the same name twice or not providing a required property inside your request body. You should receive the corresponding HTTP error codes along with the error message.
If you have all that info in a singe place, you can just go there and read it yourself. Documenting and API generally means declaring which endpoints are available, what actions are performed by each endpoint, and the parameters and return values for each of them. We have a state for each piece of information to enter, and in our request we build an object with each state. These tests are important for ensuring that the API is working correctly and consistently across different HTTP requests and endpoints.
