To retrieve a specific recipe, you could call it by its identifier in the URL: /recipes/42 To get a list, you use the GET method on the same endpoint. For an API design example, if you’re working on a cookbook API, a code example of the following API endpoint example might be: /recipes/Īs you add new recipes, you would POST them to the endpoint. Your API design will be much easier to understand if these names are descriptive. These are the “nouns” to HTTP method verbs. How do you find and determine the API endpoints of a website? A typical design pattern with REST APIs is to build your endpoints based around resources. Use Friendly and Common API Endpoint Names ![]() There are many more HTTP status codes and methods to consider, but the above lists should get you well on your way for most APIs. 503: Service unavailable, another where retry headers are useful.500: Server error, generic and worth looking at other 500-level errors instead.429: Too many requests, used for rate limiting and should include retry headers.410: Gone, the resource previously existed but does not now.404: Not found, the resource does not exist.403: Forbidden, credentials accepted but don’t have permission.401: Unauthorized, credentials not recognized.400: Bad request (client should modify the request).301: Permanently redirect to another endpoint.204: Successful request with no content returned, usually a PUT or PATCH.201: Successful request after a create, usually a POST.Much as these methods provide the request context from client to server, HTTP status codes help describe the response in the reverse direction. We won't discuss all of these in detail, however, you can check out our post on CRUD API Design for more details on CRUD vs REST.Īs you design your API, you’ll want to rely on these methods to express the primary purpose of a call rather than adding the purpose to the RESTful API URL. DELETE: remove data (usually a single resource) from your API. ![]() PATCH: updates a subset of existing data with your API.PUT: update existing data with your API.Here’s a look at the most common HTTP methods: ![]() Here's how you can design, develop, and create an HTTP REST API.įor designing REST APIs, Each HTTP request includes a method, sometimes called “HTTP verbs,” that provides a lot of context for each call. For that reason, it makes sense to structure your API around the built-in methods and status codes that are already well-defined in HTTP. However, the two developed alongside each other, and almost every RESTful API code relies upon HTTP. The definition of a RESTful API means you don’t need to use the HTTP protocol. Rather than start anew, build upon this foundation of API guidelines from thousands of successful API companies. This post helps users learn what a RESTful API is and the most common REST API design patterns, development, and principles across several categories. When designing API projects, it makes sense to build upon the REST best practices and guidelines for web services already implemented by countless others. In addition to the API architecture and recommendations outlined in Roy Fielding’s dissertation, we now have two decades of practical application.
