In Part II, we briefly mentioned what to do in case of errors that might arise from your APIs, but in this post we take a deeper dive into what to do when it all goes terribly wrong. If you want to brush up on the topics we covered in the previous posts, check them out here: RESTful API Design Part I: POST /EFF/YOU/THIS/IS/THE/RIGHT/URL RESTful API Design Part II: 418: I'm a Teapot, and Other Bad API Responses There are many ways to communicate the success or failure of an API call, but these are some of the techniques we have found to be the most intuitive here at Cloud Elements, where we integrate to a LOT of APIs. Since this is a series on RESTful APIs, we are already assuming that our API calls are being made over HTTP(S). The great thing about using HTTP for interacting with APIs is that it has built-in status codes that can give your users some good information about the success or failure of your calls. Why not make the most of them? But, but… Why? In our experience, great error messages are incredibly helpful when integrating with an API. Good error codes and messages should help guide develo

Most API http://archive.oreilly.com/pub/post/restful_error_handling.html developers spend their time on everything else involved in getting a REST API done right —from debating which resources need to be exposed through the API, to getting the error handling HTTP verbage right, to using content negotiation. Unfortunately, error responses tend to be an after-thought. They're treated as second-class citizens whose design never gets reviewed nor discussed as actively as any another component of the API. The fact is that although errors only account for a fraction of all messages sent by the API (at least typically), they are the api error handling most scrutinized messages by app developers. (Even more than success response messages!) App developers are likely to make errors when making an API request, so it's crucial to provide them with information to troubleshoot and resolve the issue. For example, the developer might forget to set a required field or the value may not match an expected format. Error responses are extremely important to get right — they determine whether developers keep building on your API or get so frustrated with cryptic error responses that they abandon the API. Unfortunately, there isn't a well defined format indicating how an error response should be structured. When it comes to transmitting errors caused due to client errors, the Box API is as RESTful as the rest of the API. All client-side errors are returned using a 4xx error code. In most cases, the API returns a 400 Bad Request. When a more specific error condition happens, the Box API also returns a finer-grained 4xx status code that indicates the error condition. Examples of such codes include 409 (when you’re t
commonly used to refer to the transmission of XML over HTTP, and the identification of XML resources via URIs. According to REST, HTTP, XML and URIs provide all the infrastructure for building robust web services, and most developers can therefore safely skip over the pain of learning SOAP and WSDL. If you are new to REST, check out Paul Prescod's excellent REST articles on xml.com. A major element of web services is planning for when things go wrong, and propagating error messages back to client applications. However, unlike SOAP, REST-based web services do not have a well-defined convention for returning error messages. In fact, after surveying a number of REST-based web services in the wild, there appear to be four different alternatives for handling errors. Below, I outline the four alternatives, and then provide my opinion on which option or combination of options is best. Option 1: Stick to HTTP Error Codes In this scenario, the web service propagates error messages via standard HTTP Error Codes. For example, assume we have the following URL: http://www.example.com/xml/book?id=1234&dev_token=ABCD1234 This service expects a single parameter: id indicating a book ID. The service extracts the id parameter, does a database look-up and returns an XML representation of the specified book. If the URL specifies an invalid or obsolete id parameter, the service returns an HTTP 404 Not Found Error Code. Option 2: Return an Empty Set In this scenario, the web service always returns back an XML document which can have 0 or more subelements. If some error occurs, an XML document with zero elements is returned. The O'Reilly Meerkat news service currently uses this approach. For example, the following URL connects to Meerkat and requests all Linux related articles from the past two days, and formats the results in RSS 0.91: http://www.oreillynet.com/meerkat/?c=cat10&t=2DAY&_fl=xml Now, try specifying an invalid category. For example, set c =ten, like this: http://www.oreillynet.com/meerkat/?c=ten&t=2DAY&_fl=rss In this case,
