Testing with HTTP Requests – via @codeship
A slow and unreliable test suite is a test suite developers won’t want to work on. In Part One of this series, I dove deeper into how you might organize classes and methods for dealing with HTTP calls. In this article, we’re going to dig into how to write tests that use data returned from external HTTP APIs. by Leigh Halliday []

API Testing – Introducing behavior-driven development (BDD) to test APIs with DHC
In a previous blog post, we introduced the testing support of DHC. We described the power of this tool to test REST services and web APIs by combining requests  and assertions. During the summer, a new version of DHC was released extending this testing support by providing a new dedicated view. by Thierry Templier []

What Does it Mean to Monitor a Web API?

Ask HN: Rest api authorization
Make sure this REST api can be used just as easily using curl. I am not sure how to do this, as I dn’t think exposing API key is a good idea. I can ask clients to hash request params with api key, but that makes it non-trivial to use with curl. []

Video: No REST – Architecting Real-Time Bulk Async APIs
Michael Uzquiano talks about how to scale API to accept many items. He examines how to evolve the Evolution of ReST over HTTP to transactional, asynchronous bulk operations. He covers job descriptors, workers, the job queue and scaling workers across an API cluster elastically. []

Convert OpenAPI Spec to Slate / Shins Markdown API Docs
Someone turned me on to an OpenAPI Spec to Slate / Shins compatible markdown converter on Github this last week. I have been an advocate for making sure we are still using machine readable API definitions for our API documentation, even if we are deploying the more attractive Slate. []

Using JavaScript to Validate API Response Bodies
In prior posts, I’ve illustrated how API Science’s JavaScript validations capability can be used to validate API response timing versus data size, API HTTP response headers, and HTTP response status codes. What hasn’t yet been investigated is how you can use the API Science JavaScript validation facility to validate the API response body. by Kevin Farnham []

REST API Notes for 2016/10/17 – Microservices Deep Cuts
Normally, in this newsletter, I like to quickly hit upon some valuable resources that bubbled up to my attention. But there’s a different class of work that takes longer to savor. However, with a bit of effort, these pieces yield tremendous insights. The first “deep cut” comes from Tom Killalea. []

Amazon today announced the List Skills API, an addition to the Alexa Skills Kit that will let developers integrate Alexa within their own list applications. The goal here is to make it as easy as possible for people to add items to their lists by asking Alexa to do it for them. []

Thinking More About API Driven Conversational Interfaces
I am spending a lot of time thinking about conversational interfaces, and how APIs are driving the voice and bot layers of the space. While I am probably not as excited about Siri, Alexa and the waves of Slack bots being developed as everyone else, I am interested in the potential when it comes to some of the technology and business approaches behind them.
