Rest API Design Best Practices to Follow

Rest API Design Best Practices to Follow

Rest API works as a bridge between the client and the business firm’s server. Simply put, it is the interpretation of the client’s commands to produce desirable results. Imagine you went to a webpage or application and asked for a specific product but got something completely irrelevant. It could happen due to malfunctioning of the Rest API design. With time comes innovation so is the case with Rest API. Many new API development formats are surfacing, but to this date, 93.4% of developers use Rest API to produce interactive applications. Research also states that 56% of developers claim that APIs help them create better products. You might question how it is possible. Well, APIs allows developers to screen essential data from other applications and customize their products according to the need of the customers.

The working mechanism of Rest API

Rest API works like any other application. The client writes a command on the HTTP protocol. The instructions in noun form are preferable, but it also uses verb commands in the form of

  • Get (used to contract desirable data)
  • Post (used to add new information)
  • Put (used to alter already existing information)
  • Delete ( used to eliminate unwanted information or resources)

Language Used in Rest API

Rest API supports JSON (JavaScript Object Notation), XML, and other languages but best works in JSON. The reason is that Java Script is in the framework of almost all websites and applications and is easy to read and write. It has extensive libraries, so there is little to no chance of mistakes.

Practices to follow while using Rest API

Using precise formatting is essential for getting fruitful results. Developers need to keep some things in mind while developing Rest API.

Correct usage of HTTP command

Developers should use correct verb commands to avoid misunderstandings. GET should always indicate the contraction of information and not the addition of new data.

Precise Instructions

The server database comprises tons of data. Users often need to extract specific information from the mountain of information. For example, if you want to access a worker's information in your company, first you need to clarify the category where the information lies, then type in the worker’s ID to avoid any inconvenience. The developer’s responsibility is to provide consistent and clear resource naming to the users.

Incorporate Pagination and Sorting

Online shopping lovers must be familiar with the pagination and sorting of products. When you visit a brand’s website, you see pages that display the brand’s products. You can also apply filters to see your desired products only. This method helps users process the data efficiently. Developers must incorporate these features to enhance the website experience.

Strengthen Security

Security is a priority issue nowadays. Business websites usually contain data about hundreds of people. Developers should incorporate passwords and authentication messages to avoid breaches. SSL encryption and HTTPS format help protect the information from any unwanted third party.

Encourage Full Documentation of the API

Consumers are not always tech geniuses. Developers should provide full instructions in the form of documentation to avoid inconvenience. On the other hand, documentation frees the developers to work closely on the API than answer mundane questions.

Frequent and thorough testing

A small error in the system may have a massive impact on the brand’s working. Frequent testing prevents mishaps from happening. After all, customer satisfaction should be the priority of developers. Various automated tools are available today for hassle-free testing of APIs.

Rest API and Hybrid Applications

Hybrid apps have the combined goodness of both web technologies, like HTML and JavaScript, and native (iOS and Android) apps. Rest API allows hybrid apps to retrieve data from the web database and display it on the mobile app screen. Instagram, Uber, and Airbnb use Rest API to send information back and forth. Rest API also provides security and authentication to the brand. The users provide their credentials and passwords to have access to the application.
