How a RESTful API server reacts to requests. This series of articles shows you how to derive an easy-to-use, robust, efficient API to serve users on the web or on mobile devices. We are using the principles of RESTful architecture over HTTP. In the first piece, we started from a list of specs for a simple bike rental service, defining URLs and the HTTP methods to serve the app. In this second part, we will talk in more detail about how the server should react to incoming requests with status codes. We will also talk about how to identify who is the user performing a request (authentication), why Cross-Origin Resource Sharing (CORS) matters for APIs, how caching can improve performance, and how HTTP optimistic locking can prevent inconsistencies in resources. Here is where we left off from the previous post: we have the URLs (nouns) and the HTTP methods (actions) our API responds to. O'Reilly Programming Newsletter For these URLs + methods, we already defined some basic structure of the responses to valid requests.
Great! Great! Architecture - Transactions across REST microservices? REST APIs and Next Generation Threats: Part 1 - CISO Platform. Some days back, when I was going through the record breaking statistics of Facebook and its social networking platform’s REST APIs, I found phrases like“People on Facebook install 20 million applications every day. More than 2.5 million websites have integrated with Facebook”. It really shows the incredible power of REST APIs and probably it is just a start. Apart from Facebook, the list of API providerapplications providing REST APIs is increasing day by day, some of these applications include LinkedIn, Google, Bing, Delicious, GroupOn, Paypal, Twitter, Salesforce and so on.
The number of 3rd party applications built on top of REST APIs is also drastically increasing. Probably, we are going to see atleast thousands of 3rd party applications in the near future, built on top of REST APIs, creating a true mesh of applications never seen before.

Scenario 1: Who needs connectors when we have Web APIs (Into the wild BLUE yonder!) By Robert Vila and Jerry Cuomo - November 2014 USB and Web APIs have something in common If you’re like me, you remember having a drawer filled with different types of hardware connectors and adapters. Your keyboard, mouse, network adapter, phone and dozens of other peripherals had their own proprietary type of connectors.
Each device was designed for a unique type of socket and worked with only one protocol. It was a mess. And then came USB. In the world of software, we’ve struggled with the equivalent of a drawer of outdated cables and adapters. The software industry is finally taking the next step. Connectors Built for a Bygone Era Most software connectors, associated protocols and data formats were established before the eras of cloud, mobile and the Web. These assumptions are no longer true, but most software connectors still act as if these limitations exist today. A good example is the SWIFT data format. Ghosts of Connectors Past An API-Driven Connector Model In Summary. APIs 101 - Integration Help & Support | Zapier. REST or SOAP in a cloud-native environment. Cloud-based API data models have not only enhanced the cloud experience, but also provided a way for developers and administrators to integrate workloads into the cloud using those APIs.
For most enterprises, APIs let share information across various on-premises and cloud-based applications. They also play an important role to integrate platform workloads more seamlessly. As cloud adoption continues to grow, there is more demand for integration points between applications inside and outside of the cloud environment. Rise of multicloud strategy along with need for enhancement in cross cloud capabilities have increased the dependency on cloud API environment. But which approach is better and what support do you get in your cloud environment? SOAP in a nutshell SOAP (short for Simple Object Access Protocol), the older approach, had industrywide support ranging from product companies such as IBM and Microsoft to service implementers.
Why SOAP or REST? Links to posts, talks and slides talking about API design, arquitecture, testing, tools, etc. Best books in API design. Good API design is such a broad topic (because there are a wealth of programming languages and ways you can communicate with systems and code) that you're not going to find one that probably suits you without being more specific.
Lets assume you are talking about a class API (like a C, C++, Java API for example) and are just either defining a library or an interface into your application from code that is loaded from the application's runtime environment. In that case I could say what you might look into first would be good OO design and head you off into "Design Patterns" as a classic (there is also an online Java equivalent of that book which I think is "Java Design Patterns"). But then you'll spend your years as a junior and mid-tier developer obsessed with designs and which design to best use. Having the right classes that "make sense" to a developer is wise, but spending too much time with patterns isn't. No REST for the wicked. This article (also read as rant) was heavy inspired by the reading of this article, which puts in words something that was floating in my mind a lot these years of making services talking between each others, being API, mobile client or whatever.
Why the fuck are we using REST~ish API everywhere? The Problem It seems that nowadays a decent developer MUST know and use REST, but how we are doing it? It’s pretty much clear to me implementing it or just consume it that there’s a lot wrong. Main points are covered by the article cited at the beginning, but I’ll just remark some of them: 1.
And makes use of it scattering logic around too much: headers, verbs, uris, response codes and body. Do I need to provide an header or a token in the query string to authenticate calls? 2. This is harshly true because REST is designed after the concept of resource, CRUD operations and linking them. Register a user -> PUT, POST user resource? Existing solutions An idea… The new idea is an old idea. WTF is an API? Banking Sector Embraces Multi-Cloud. Source: Shutterstock The financial services sector tends to be a bellwether for early adoption of disruptive technologies. For example, financial services giant Goldman Sachs played a key role in forging an application container specification in 2015 as the transformative framework was just gathering momentum.
A new study commissioned by software vendor Canonical and released this week finds that the financial services sector is now embracing multiple cloud deployments and accompanying components ranging from machine learning to containers. Among the motivations are better availability of cloud services, improved application performance and the ability to comply with financial regulations by isolating customer data in portable, ephemeral containers. The report compiled by 451 Research found that 60 percent of North America, European, Middle Eastern and African financial services businesses expect to adopt multi-cloud IT architectures over the next two years.

RESTful APIs - An accurate description - Johno the Coder. Hi everyone Today I thought I would do a quick post to cover RESTful APIs, and what they are. The reason for this article is that I have, on numerous occasions, encountered developers (and indeed whole teams) who have misunderstood this concept at its very core.
This causes a number of problems, firstly if you don’t understand RESTful APIs fundamentally, you’re likely to encounter integration issues quite early on. Secondly, unfortunately, if you’re a candidate interviewing for a role and haven’t understood what a RESTful API is properly, you’ll come unstuck in interview. What RESTful is not (necessarily) A buzzword for a JSON APIAn API with obscure functionality What a RESTful API is, and what it has Okay, so explain to me the HTTP methods/verbs How does that work in practice?

In a previous blog post, we shared best practices for designing a microservices architecture, based on Adrian Cockcroft’s presentation at nginx.conf 2014 about his experience as Director of Web Engineering and then Cloud Architect at Netflix. In this follow‑up post, we’ll review his recommendations for retooling your development team and processes for a smooth transition to microservices.
Optimize for Speed, not Efficiency The top lesson that Cockcroft learned at Netflix is that speed wins in the marketplace. If you ask any developer whether a slower development process is better, no one ever says yes. Nor do management or customers ever complain that your development cycle is too fast for them. Netflix made an early decision to optimize for speed. This approach turns the usual paradigm of optimizing for efficiency on its head. In Cockcroft’s experience, if you say “I’m doing this because it’s more efficient”, the unintended result is that you’re slowing someone else down. API plan endpoint mapping – Instant API.
You may be wondering what exactly we mean with the title and the answer is this. Most APIs have endpoints created that are not available to all users of that API. For example there can be some internal administrative based calls used by your APPs backend, a trial plan or basic plan that only exposes some API endpoints / features and more complex plans that have additional API endpoints /features. This is normally quite a complex thing to achieve when it comes to API management, and making it as easy as we have was quite a challenge. Rather than waste time talking about how we east we make this process, look at the video below to see this part of API Subscriber Plan management in action. As you can see we have made it very easy to exclude or include any of your endpoints via simple drag and drop operations. Once you save a Plan this will be deployed to your Pay2Play and Appliance Endpoints within seconds and ready for use. API Endpoint Testing with Postman – Server Side Swift and More.
Testing, reproducible results, and well defined functional specifications are the life-blood of a well designed and well functioning API. Testing itself has several phases, beginning with creating unit tests to verify operation of individual code components, through to integration testing where you start plugging pieces of your API ecosystem together.
Once your API has passed it’s unit and integration testing, the next phase is “System testing”. System testing is defined as: “testing conducted on a complete, integrated system to evaluate the system’s compliance with its specified requirements. System testing falls within the scope of black-box testing, and as such, should require no knowledge of the inner design of the code or logic” ( This is where external tools like Postman ( come into focus. Getting set up The Readme.md of the repo also has a link to a Postman API test group. Testing in Postman Now, delete. Your webhooks endpoint should do almost nothing – jsneedles. Everyone has a webhook nowadays; whether it be monitoring a build on GitHub, receiving an analytics callback or ever processing customer payments… webhooks are becoming a dominant form of standardized communication between machines.
A common mistake developers make when implementing a webhooks receiver is doing too much within the receiving request itself. Imagine you have a service that needs to recieve anywhere from 0–40,000 webhooks per minute. That’s a large variance that your server needs to be able to handle. If processing these webhooks is mission critical your service can’t fail under high load. The solution to this problem is to use a decoupled producer (webhooks receiver) & consumer (job processor) connected via a job queue. Recently, I had to implement this… Your receiver & your processor should be two different things!
The most important thing about building a highly efficient and scalable receiver is to make sure it does as little as possible. Azure Storage Queues Results.

<? REST APIs must be hypertext-driven » Untangled. I am getting frustrated by the number of people calling any HTTP-based interface a REST API. Today’s example is the SocialSite REST API. That is RPC. It screams RPC. There is so much coupling on display that it should be given an X rating. What needs to be done to make the REST architectural style clear on the notion that hypertext is a constraint? In other words, if the engine of application state (and hence the API) is not being driven by hypertext, then it cannot be RESTful and cannot be a REST API. API designers, please note the following rules before calling your creation a REST API: A REST API should not be dependent on any single communication protocol, though its successful mapping to a given protocol may be dependent on the availability of metadata, choice of methods, etc.
There are probably other rules that I am forgetting, but the above are the rules related to the hypertext constraint that are most often violated within so-called REST APIs. Introduction.
