For this blog, I chose the blog “REST API Design Best Practices Guide” from PostPilot. I chose this resource because our course directly works with REST API, focused on backend development, and how different software components communicate through REST API. Since REST APIs are one of the most common ways to build websites, I felt it was important to reinforce what I learned in class about how to work with REST API.
The blog explains the core principles behind REST, including having a stateless server, a client server relationship, caching, and interfaces. It then goes into the basics for building APIs that are easy to understand. One of the first practices it suggests introduces designing resource based URLs using nouns instead of verbs and making them simple and plural such as users or orders. It also emphasizes the importance of properly using HTTP methods, like GET for retrieving information, POST for creating data, PUT or PATCH for updates, and DELETE for removal. The guide goes deeper by discussing when to use path parameters versus query parameters, especially for filtering data and explains why good responses help developers with context and confusion.
Something I found especially insightful was the explanation on versioning and error handling. The blog explains why APIs should include versioning so that future updates don’t break existing clients. It also explains why providing consistent and descriptive error responses are important so that developers can debug what went wrong rather than guessing. It also talks about security requirements such as using HTTPS and authentication tokens, as well as using tools like Swagger to make the API easier for other developers to use.
This blog improved my understanding after reading it, I’ve noticed that good planning and design are crucial, especially when multiple people use the same system. I noticed that the HTTP method already conveys the idea, so keeping endpoints focused on resources makes everything cleaner.
Hopefully, I can apply what I learned in future API work, particularly when working with backend development. This blog’s information will definitely be helpful when designing good and useful APIs rather than messy and unreadable designs. This blog has made me more aware and informed of how important API design is, not just for functionality but for maintainability and ease of use. Reading this guide along with that I’ve picked up in class gives me a strong foundation to understanding REST APIs, if not at least be a little more informed on the topic..
