3 Methods for Documenting JSON API Services

JSON is a very powerful, open standard format that is used by many services and APIs across the internet. Unfortunately, while open standard carries a lot of good, it also creates some pitfalls that developers may not be prepared to handle. One of these pitfalls is that, in combination with being widely used, the open…

How to Wrap a REST API in GraphQL

How to Wrap a REST API in GraphQL

GraphQL is a powerful tool that we’ve discussed previously at Nordic APIs. As with any emergent tool in the API space, however, there’s some disagreement on exactly how to implement it, and what the best practices for its implementation and use case scenarios are. Have no fear, dear reader — we’re here to sort this…

Asynchronous APIs in Choreographed Microservices

When building microservices you have to first make a decision: How am I going to manage service-to-service communication? Most developers will answer immediately: API calls. But then, more questions come to mind: Am I going to call services directly? Doesn’t it block the caller service? Doesn’t it introduce a dependency between both services? What if…

5 Potential Benefits of Integrating GraphQL

GraphQL is incredibly powerful — so powerful, in fact, that it is used by corporations such as Facebook to drive their large, complex social systems for billions of users. Despite this, the language is still relatively nascent, and its usage has yet to reach the dizzying heights that those languages it replaces and augments occupy….

Building and Enforcing an Internal API Style Guide

API Design: Building and Enforcing an Internal Style Guide

In our recent post on tips for starting a public API journey we touched briefly on the idea of creating a style guide that helps API providers produce well-constructed and consistent APIs as part of their public API offering. The creation of an API style guide is, however relevant for API providers regardless of whether…

Your API is never fully released

Your API is Never Fully Released

The modern development landscape has changed from when APIs were first being developed. Gone are the days where developers could “develop and forget”, releasing APIs, systems, or applications to the public for consumption and use. Today, there isn’t really such a thing as a release in the common parlance of yesteryear. When a developer releases…

Top Specification Formats for REST APIs

Documentation will set you free. Whether your API is for internal, private use, or for extensive public interaction, proper documentation can make or break an API. It’s not just a tool for developers, either — proper API documentation can drive API adoption more than any other tool within the API provider’s grasp. In this piece,…

How Far Should API Definition Languages Go?

The most common API definition languages we spot in the wild are Swagger / OpenAPI Spec, RAML and API Blueprint. All three let you define your endpoints, your resources, your query or path parameters, your headers, status codes, security schemes, and more. In a nutshell, these definition languages define the structure of your API, and…

Why API Developer Experience Matters More Than Ever

Whether or not you focus on DX design, your developers are always experiencing your API, and that experience may either be positive or negative. Ronnie Mitra is the director of API design at the API Academy, which has a singular focus on API design and implementation best practices. Mitra is an advocate that an API must be designed with its reader in mind.

Beautiful UI Design for API Developer Portals

When we think of Application Programming Interfaces — APIs — we may not immediately pair them with User Interface design. Implemented as a background tool, APIs are largely in the hands of developers, and technical documentation has a natural reputation of being elusive for laymen. However, this mindset is not sustainable. User Interface (UI) is…

API Design & Testing State of the Art

Ensuring proper APIs functionality raises all the following questions: How do you decide which endpoints you’re going to expose with your API? How do you create all the documentation that developers will use to interact with your API? What is the best way to verify that your API is working as specified by the documentation,…

Content Negotiation For Web API Longevity

Every so often, a new image file format comes along that does a better job of compressing images than JPEG or PNG. We’ve seen Google pushing its own Webp format, (purportedly 26% smaller in size compared to PNGs), and new formats BPG and FLIF are contenders, packaging images in less and less space and time…

How to Improve API Experience Using Hypermedia

One of the greatest ways to improve and sustain an API userbase is by enhancing developer experience. A way to do this is by improving the usability of an API with hypermedia — a method of interacting with APIs. But what exactly is hypermedia, why is it important, and how will it affect an API…

HTML Hypermedia APIs and Adaptive Web Design
Gustaf Nilsson Kotte - Jayway - March 2013

The many different types of connected devices are increasing dramatically. We already have a large amount of duplicate code between client applications (both native and web), and the increasing number of devices is only making this worse. Also, cheap low-end devices are gaining greater market shares, and users expect a good experience when using our software on them. To solve the problem of code duplication on the clients, we need to pull as much of it as we can back from the clients to the server. A good way to achieve this is to build a Hypermedia API and to use HTML as the media type for the API. 

Microservices Anti-Patterns
Tammer Saleh - Pivotal Software - 21/20/2014

It seems everyone’s talking about microservices, lately, but few appear to have given any real thought to best practices around building and deploying them. In this talk, we’ll highlight many of the mistakes we’ve seen people make when building a microservices architecture

Token-Based Architecture Design
R. Kevin Nelson - 21/10/2014

In the course of designing and using web APIs, you’re bound to encounter tokens. They are everywhere: access tokens for OAuth, CSRF tokens for security, reset tokens for passwords. Because of their ubiquity, they’re easy to overlook, but token design actually plays a huge role in shaping your application architecture. This presentation surveys API architectural archetypes through the lens of tokens, and how they can facilitate (or inhibit) your platform’s scalability.
