When people ask me how to grow in AI, I tell them it comes down to four fundamentals. Think of it as a stool. If one leg is missing, the whole thing wobbles. The legs are API, markdown files, JSON, and JavaScript. None of them are exotic or reserved for engineers. They're just the practical foundations that let you move from being a passive user to someone who can actually build with AI.
Let's start with the first leg: API.
Here's the honest truth. When I talk to folks in L&D or marketing, a lot of them don't really know what an API is. They nod along politely, but if you pressed them, they couldn't explain it. And I don't blame them. Most of us didn't go into this field to learn tech jargon. So let's clear the fog.
An API, or Application Programming Interface, is a set of rules and connections that lets two pieces of software talk to each other. It's not a program by itself, and it doesn't "do" the work. It defines the pathway so one system can request something from another and get a predictable response back. That predictability is the key. Without APIs, every system would need a custom-built translation layer, and nothing would fit together.
Think about ordering food through DoorDash. The app doesn't make your meal. It passes the order, in the exact format the restaurant's system expects, and gets back a confirmation. Or take checking the weather on your phone. Your app isn't reading satellite data directly. It makes a structured request to a weather service, and that service replies in a format the app understands. That handoff happens because of an API.
The same is true for AI. The chatbot you're using right now is built on top of an API. The chatbot is a polished surface designed to make things easy. The API is the real doorway into the kitchen. That's where you get the full set of ingredients, not just what's printed on the menu. In the context of learning systems, think of ChatGPT as the interface sitting between you and your LMS. It makes the experience approachable, but you're still playing with the settings someone else chose. The API, on the other hand, is your way to connect directly into that LMS and control how learning content is delivered, tracked, and adapted.
And here's why that matters for us. Staying in the chatbot feels safe, but it limits what you can do. You're stuck with someone else's defaults. Once you step into the API, you start to see new possibilities. You can adjust how the AI behaves, automate repetitive work, and connect it directly into your tools. You stop bouncing between tabs and start building flows that actually match your day-to-day.
I've seen what happens when people cross that bridge. They stop thinking of AI as a gimmick and start using it as part of their craft. A trainer builds a helpdesk that answers common learner questions. A marketer wires up a script that organizes survey results in minutes instead of hours. These aren't grand enterprise systems. They're simple pilots that show you what's possible once you take the first step.
