Naming Conventions in REST APIs: Best Practices and Examples

Introduction:

REST APIs are the backbone of modern web and mobile applications. They allow developers to access data and functionality from external services and servers, which can significantly enhance the user experience and functionality of the application. One of the critical components of REST APIs is the naming convention used to identify and access the various available resources. In this article, we will discuss best practices for naming conventions in REST APIs and provide examples of how to name resources.

What is Naming Convention?

A naming convention is a set of rules determining the naming of resources in REST APIs. It helps to keep the resources organized and easy to understand for both the client and the server.

The Importance of Naming Conventions in REST APIs:

Having a consistent and intuitive naming convention is crucial for REST APIs for several reasons:

• 1. It makes the API easier to use for developers. They can quickly understand what each resource represents and how to access it.
• 2. A straightforward naming convention makes it easier for API developers to maintain and update the API over time.
• 3. A well-defined naming convention can improve the overall security of the API by reducing the risk of naming collisions or misconfigurations.

Naming Conventions in REST APIs:

Best Practices There are several best practices to consider when naming resources in REST APIs:

• Use nouns: Resource names should be nouns, not verbs. This makes it easier to understand what the resource represents. For example, instead of using "getUser", use "user".
• Use plural nouns: Resource names should be plural nouns, such as "users" or "posts", to indicate that the resource represents a collection of items.
• Use hyphens: Hyphens can be used to separate words in the resource name, making it easier to read. For example, instead of using "userprofile", use "user-profile".
• Be descriptive: Resource names should be descriptive, making it clear what the resource represents. For example, instead of using "data", use "customer-data".
• Be consistent: Resource names should be consistent across the API. For example, if you use "user" to represent a user resource, don't use "account" in another part of the API to represent the same resource.

Examples of Naming Conventions in REST APIs:

Here are some examples of how to name resources in REST APIs:

• Users: "users"
• Posts: "posts"
• Comments: "comments"
• User Profile: "user-profile"
• Customer Data: "customer-data"

Conclusion:

Having a clear and consistent naming convention is crucial for the success of REST APIs. By following best practices, such as using nouns, plural nouns, hyphens, descriptive names, and consistency, developers can ensure that their API is easy to use, maintain, and secure. Additionally, by providing examples of how to name resources, developers can ensure that their API is intuitive and easy to understand for other developers who may use it.

This is very apt in terms of naming the resources. In most of my findings as architectural reviews or API reviews from a consumer perspective, this 101 should be taught to all backend developers on the first day. Because, once an API is shipped, it is cumbersome to do changes, or deprecate it without any impact.

Let's imagine the **PARTNER **entity.
I need: register, block, unblock, change and some oher actions for this entity.
How should I use nouns only?
POST /v1/partner/register
PATCH /v1/partner/block
PATCH /v1/partner/unblock
PATCH /v1/partner/change(modify)
.....
???

I will stick standard naming convention but for partner, I will add it to custom HTTP header.
