When REST Goes Wrong: The HTTP Verb Abuse Hotline

When REST Goes Wrong: The HTTP Verb Abuse Hotline

REST is a beautiful architectural style… in theory. In practice, it's often a dumpster fire of misused HTTP verbs and resource naming conventions that would make Roy Fielding weep. I’m talking about APIs where every single operation is a `POST` request, regardless of whether you're retrieving data, updating a resource, or sacrificing a goat to the server gods.

The POST-Apocalypse

I once inherited an API that used `POST` for *everything*. Getting a user? `POST`. Updating a profile? `POST`. Deleting a comment? You guessed it: `POST`. Debugging was a nightmare. Every request looked identical in the logs. It was like trying to find a specific grain of sand on a beach made entirely of identical grains of sand. Moral of the story: learn your HTTP verbs, people! `GET` is for retrieval, `POST` is for creation, `PUT` is for complete replacement, `PATCH` is for partial updates, and `DELETE` is for, well, deleting. It's not rocket science, unless you're building a rocket API, then maybe it is. But even then…

The Mystery of the Missing Documentation (and the Case of the Confusing Endpoints)

Ah, documentation. The unicorn of the development world. We all hear about it, some claim to have seen it, but most of us end up stumbling around in the dark, armed with nothing but `curl` and a vague hope that something will eventually work. And when you *do* find documentation, it's often outdated, incomplete, or written in Klingon.

Endpoint Naming Conventions: A Horror Story

I’ve seen API endpoints named things like `/v2/users/getUserInfo/doItNow`. Seriously? What's the `doItNow` part adding? Is there a `doItLater` version I’m missing out on? And don't even get me started on inconsistent naming schemes. One endpoint uses snake_case, another camelCase, and a third uses PascalCase just to keep you on your toes. It's API chaos! Good API design means consistent, predictable, and self-documenting endpoints. Think `/users/{userId}` or `/products/{productId}`. Simple, elegant, and understandable, even at 3 AM when you're three coffees deep trying to fix a production bug.

The Great Data Format Debacle

Choosing a data format is like choosing a pizza topping: there's a right answer (pepperoni), but people will still argue about it. JSON is the industry standard, but some APIs insist on using XML (shudder) or, worse, some custom, home-brewed format that requires you to decipher a Rosetta Stone made of regex.

And then there's the inconsistent use of data types. Sometimes a number is a string, sometimes a boolean is an integer (0 or 1, because true/false is *too* mainstream), and sometimes a date is just a random number of seconds since the Big Bang. It's like the API is actively trying to gaslight you into questioning your sanity. The key is to be consistent and use standard data types. Please, for the love of all that is holy, use ISO 8601 for dates!

Authentication Antics: When Security Goes Sideways

Security is paramount, but it doesn't have to be a pain in the ASCII. Poorly designed authentication schemes can be a major source of frustration for developers. I’m talking about overly complex OAuth flows that require you to sign your soul away to get an access token, or APIs that still rely on basic authentication with passwords sent in plain text (yes, these still exist, sadly).

The OAuth Overkill

OAuth is great for delegating access, but using it for simple API access within your own organization is like using a sledgehammer to crack a nut. It adds unnecessary complexity and overhead. Consider using API keys or JWTs (JSON Web Tokens) for internal APIs. They're simpler to implement and manage.

The Plain Text Password Party

If your API is still sending passwords in plain text, I'm not even sure what to say. You're basically inviting hackers to come in and steal all your data. Please, for the sake of your users, use HTTPS and proper hashing algorithms. It's not that hard. Like, *really* not that hard. Seriously, go do it now. I'll wait.

The Rate Limiting Riddle

Rate limiting is necessary to prevent abuse, but it should be implemented thoughtfully. An API that randomly throttles requests without any clear explanation or predictable pattern is just asking for trouble. Provide clear error messages and include rate limit headers in the response so developers know when they're approaching the limit. Bonus points for allowing developers to request higher rate limits.

The Bottom Line

Designing a good API is like building a good house: you need a solid foundation (a clear understanding of REST principles), a well-defined blueprint (comprehensive documentation), and quality materials (consistent data formats and secure authentication). Avoid the common pitfalls of verb abuse, confusing endpoints, and inconsistent data types, and your API will be a pleasure to use, not a source of endless frustration. And remember, a little empathy goes a long way. Put yourself in the shoes of the developer who will be using your API, and ask yourself: “Would *I* want to use this abomination?” If the answer is no, go back to the drawing board. Or consider the llama farm.
