Where Do I Go To Learn About APIs?

It is the top question I get–where do I go to learn about APIs? I’ve long had a list of the blogs, directories, podcasts, and other resources for learning about APIs–the trick is to keep it up to date and always properly reflect what is truly happening. I’ve reworked my previous work on this subject while at Postman as a YAML powered blog post that I will dynamically update on a regular basis.

I recommend beginning with the top blogs and newsletter, and tune into the podcasts as you have time. Then make sure you explore the directories and catalogs to look at the different types of APIs, and get more familiar with the space. Then as you develop more awareness you can engage more within the community, digest the various reports, and find what types of API knowledge and information interests you the most.

API Blogs and and News Sites

These are the blogs I tune into and recommend you subscribe to when looking for a way to tune into the API space.

	Nordic APIs - We’re an international community of API practitioners and enthusiasts. Our mission is to help organizations make smarter tech decisions using APIs.

I have been working in the financial industry for 18 years and my job was always around connecting pieces of software together, hence creating and using web services or APIs. My current daily job is helping people, from executive to developers and everything in between, to understand what are APIs, why they matters and how to do them. I also help dozens of different teams to design their APIs by reviewing and challenging their designs, training them to design API and also building API design guidelines.

API Catalogs, Directories, Networks, and Discovery

Places where you can actually find APIs that you can use.</p>

	Postman API Network - The Postman API Network provides a central place for both API consumers and API producers to easily discover, explore, and share APIs. The Postman API Network has two parts, a public network and a private network. The Postman Public API Network is open to the entire API community, while the Postman Private API Network is for your team only.
	RapidAPI - There are millions of software programs out there and they’re reshaping every aspect of our lives. We believe that they can get exponentially better by sharing data and functionality with each other. APIs are the language that software uses to communicate and connect. RapidAPI is the world’s largest API marketplace. RapidAPI lets you manage all your API integrations from one place and gives you real-time performance metrics.
	SmartAPI - The SmartAPI project aims to maximize the FAIRness (Findability, Accessibility, Interoperability, and Reusability) of web-based Application Programming Interfaces (APIs). Rich metadata is essential to properly describe your API so that it becomes discoverable, connected, and reusable. We have developed a openAPI-based specification for defining the key API metadata elements and value sets. SmartAPI's leverage the Open API specification v3 and JSON-LD for providing semantically annotated JSON content that can be treated as Linked Data.

	Reddit r/api - The Reddit channel all about application programming interfaces.
	Stack Overflow - This is the official API tag and conversation around it on Stack Overflow.

API Events

This is where you can tune into the conferences and events occurring across the space and rub elbows with folks who are doing APIs.

Nordic APIs - We’re an international community of API practitioners and enthusiasts. Our mission is to help organizations make smarter tech decisions using APIs. We do this through knowledge and information sharing via our blog and events. Nordic APIs was formed to help businesses become more innovative, lean, and efficient.

Some of these images need updating, and it was interesting to see which sites had gone away or went dormant. I will spend some more time curating what is here, and I think I will add OpenAPI, JSON Schema, AsyncAPI, and the leading API specifications to the list. They have communities, newsletters, etc. that are worth tuning into. I am also going to work to try and get outside the echo chamber a bit and see if I can’t find other avenues for driving API discussion amongst the normals.

If you see a mistake, something you’d like to fix or add, feel free to submit a pull request on the YAML powering this page, or submit an issue. I’ll regularly update this blog post, a recurring theme I am seeing, where I need to treat some posts as evergreen and power using YAML, keeping them up to date with what I am seeing, rather than launching a new landing page or micro site. If you have a questions don’t hesitate to ask, and if I have a resource to share I will make sure to add to my list.
