One problem with building applications that talk to external dependencies like APIs, is that the applications are talking to external dependencies. This opens up a whole can of worms when it comes to testing the application. You may well have heard developers saying: don’t let tests hit external dependencies!
Validation can mean a lot of things, but in API land it generally means figuring out if the data being sent to the API is any good or not. Validation can happen in a lot of different places - it can happen on the server, and it can happen in
Nobody out there thinks you should always use REST for every single API being built, nor should you ever use any one paradigm for everything, but a growing number of people misunderstand REST so badly they think they never need it. As with most things, there is a whole bunch
Dealing with the Happy Path™ in an API is pretty easy: When a client asks for a resource, show them the resource. When they trigger a procedure, let them know if it was triggered OK, and maybe if it completed without a problem. What to do when something doesn’t
Recently a bunch of us API nerds got into a big old chat about what to call what you are writing when you write OpenAPI for your API. Some people call it the API specification, others think that "specification" is a word reserved only for the markdown file
Another guest post from our friend Darrel Miller. This is my attempt to make the HTTPbis caching rules more accessible and hopefully shine a light on how powerful HTTP caching can be. I’ve been working on a Pluralsight course that talks about how to use the Microsoft HttpClient library.

Designing the world's most beautiful API is only half the story, somebody needs to interact with it!
Written by Fran Méndez and re-posted here with permission. A recurring question that I get very often is: "how do I organize my AsyncAPI documents?". Also, the related one: "I have two services, a publisher and a consumer, should I define both in the same AsyncAPI document?
Written by Darrel Miller, on his blog Bizcoder.com. This article makes a case for trying to acoid batch requests (or compound documents, included resources, etc) in situations that make interactions slower. HTTP/2 is here, and we need tos foip some of the ways we think on our head!

Everyone and their dog wants an API, so you should probably learn how to build them.
In a system-oriented architecture, it is crucial to communicate with other systems. In an ideal world each service knows enough information to satisfy its clients, but often there are unfortunate requirements for data to be fetched on the fly. Broker patterns, proxies, etc., or even just a remote procedure being
Is your API working right now? It can be a tough question to answer. A lot of monitoring tools are out there, like Prometheus which can track all sorts of metrics, but that assumes metrics are being sent to it which let you know there’s a problem. Maybe NewRelic
