Hello Readers, This is the last article of the Year 2023.
In this article, we will figure out 7 Proven Strategies for the Best API Design Practices.
So, Let’s begin.
Follow the below practices for creating the Best API for Seamless Integration
1. Do not use Verbs in URI
The best API design needs the best practices to follow. We ought to try not to use Verbs in API URI. Why? Since the HTTP request technique that we use as of now comprises a verb. Having verbs in the REST API endpoint way sits unused and, in this manner, is superfluous as it brings no new data.
2. Use JSON
REST empowers utilizing different data exchange formats like JSON, RSS, XML, CSV, and HTML. Albeit, this altogether relies upon why you require your API and the application you have. Assuming you have a public-confronting API that you wish to be accessible using the REST API design, you should pick JSON data format. Practically in the vast majority of cases, JSON is the most favored data design for connecting payload and response.
3. Apply Caching
You can add caching to bring back data from the memory cache as opposed to requesting the database to get the data each time. A brilliant reason behind caching is that clients can fetch data much more quickly.
There are a few sorts of caching techniques, for example, in-memory caching, Redis, and so on.
4. Error Handling
To remove any conflict for all API clients, errors and exceptions should be dealt with effortlessly, in this manner returning the HTTP response codes that signify the idea of the error that has occurred. This gives the API consumer adequate data to analyze the source and reason for the issue.
Let’s have a look at a list of common error HTTP status codes.
- 400 Bad Requests
- 401 Unauthorized
- 403 Forbidden
- 404 Not Found
- 500 Internal server error
- 502 Bad Gateway
- 503 Service Unavailable
5. API Documentation
It is very fundamental to publish your API documentation. Not only does it help developers, but also users too. At the point when you distribute the API documentation, developers view what they are managing while at the same time making an execution. Other than this, publishing API documentation empowers expected users to investigate what is made accessible through your API.
API Documentation should offer data concerning the current techniques and endpoints, potential response codes, request/response models, and data about authorization.
6. Use SSL to secure the API
The full form of SSL is a secure socket layer. It is significant for security in the REST API plan. This will get your API and make it less vulnerable to pernicious attacks.
SSL certificates are not hard to load to a server and are not costly to purchase in situations where they are not accessible free of cost.
7. API Versioning
We ought to have various versions of API assuming we’re rolling out any improvements to them that might break clients. The forming should be possible as per semantic variant like most applications do these days.
So along these lines, the v1 endpoint can remain active for clients who would rather not change, while the v2, with its brand new elements, can serve the clients who are prepared to update.
