Sure, you might be feeling that the REST API has delivered no norms or rulebook to observe when creating your representational state transfer app interface. Nevertheless, we at Skyhidev have recognized and are rehearsing these best practices for REST API design.

Since the beginning of the rest-api system as uncovered by Roy Fielding in the year 2000 and over these 20 years of software development, we have adjusted these REST API best methods design in 2021. We hope they will ride up to be useful to you too.

What is REST API?

Let us start from conception. For those who like to get the exact idea of the REST API development, we’re here with the description:

“REST denotes Representational State Transfer, and it is an API. Additionally, the HTTP communication protocol specifically accesses it”.

3 Most useful Traits of REST API Architecture Design

1. Easy to Work with and Easy to View:

A well-grounded API will be uncomplicated to perform with. Its resources and other affiliated operations should be fast dedicated to memory by developers who haggle with it always. Thus, an awesome API should be trouble-free to read and write. Only then the designers and developers are fulfilled enacting with it.

2. Tough to misusage:

Integration with an API having a useful design will be relatively straightforward when writing wrong code becomes less potential to happen. It has scholarly feedback and does not implement any stringent guidelines on the API end customer.

3. Outright & straightforward:

With brevity, we mean that a wide API will enable developers to develop full-fledged applications in resistance to your revealed data. Usually, wholeness takes position over a period, and full API designers gradually build on top of the existing APIs. Thus, this is an immaculate trait of the most useful API design that every association or an engineer having an API should be reserved too.

REST API Best Practices

1. Use Nouns and not Verbs in URI

REST APIs must be created for resources that can be useful, entities, etc. Therefore, they should invariably consist of nouns and not verbs. This indicates that we must abstain from using verbs in REST endpoint approaches. Rather, we must enforce nouns that depict a certain entity.

2. Hypermedia as the engine of application state (HATEOAS)

This regulation stands out for several different network application architectures from the REST API development. The Hypermedia As Transfer Engine Of Application delivers effortless navigation through individual resources and their general actions. By this, a customer is not needed to know how to disseminate with an application for specific actions because each of the metadata gets implanted in the answers sent from the server.

3. Swagger

Swagger is a famous and broadly utilized tool that is employed to document REST APIs. It shows a way to investigate the use of a distinct API, thereby allowing developers to be conscious of the fundamental Semantic conduct. To be more specific, it is an analytical method of comprising documentation using annotations that additionally gives rise to a JSON that represents APIs and their use.

4. Use only JSON

REST allows using different output formats like JSON, RSS, XML, CSV, and HTML. Although, this totally depends on what you need your API for and the application you have. If you have a public-facing benefit that you wish to be known via REST API design, you must pick JSON data format. Basically, in 99% of subjects, JSON is the best data format for interacting between payload and response.

5. Authorize filtering, sorting, and pagination

A few key elements for consuming API contain filtering, sorting, and paging. Often, resource collection can be massive. The databases behind REST API norms can also get huge. Ultimately, it brings down the implementation of our systems. To eliminate these, we can employ,

  • Filtering: To shrink the query impacts by individual parameters. For example, country or product date, etc.
  • Sorting: This allows sorting the outcomes in an ascending or descending hierarchy by a selected parameter/(s). For instance, by date.
  • Paging: It uses ‘limit’ to tighten down the count of effects displayed to a specific number and ‘offset’ to designate the part of the result content to be displayed. This is meaningful in cases where the tally of total outcomes is more sumptuous than the ones submitted.

6. Implementation optimization with Caching

You can add caching to obtain back data from the local memory cache instead of querying the database for receiving the data every time you expect to recover any data asked by the users. An ideal point of caching is that users can acquire data even speedily. However, many times, the data achieved by users might be obsolete. Ultimately, this can conduct to major concerns while debugging in production circumstances, as anything might go amiss because users occupy old data.


The principal takeaway needed to create high-quality REST API norms is maintaining consistency by adhering to patterns and web standards. Developers are needed to reserve a good time to conceive REST APIs. Why? Because APIs hold the ability to turn any assistance excessively easy or extremely problematic.

When it comes to the current web, JSON, HTTP, SSL/TLS status codes are some common building alliances. As a quick wrap-up, we ought to put emphasis on performance as well. To promote performance, make sure you don’t produce too much data simultaneously. With caching, you don’t require to query for data each moment. Further, maintain consistency in the ways of endpoints. This was an article that states the top REST API best practices. Peeking for expressive architecture design, Skyhidev is the right opening for your business.
