Why I Registered for an API Course

I run about sixty-five sites. Most of them are static. Hugo builds them, Cloudflare serves them, and I paste content into a text editor like it’s 2009. That works, and I’m not going to pretend it doesn’t. But every week I find myself doing something by hand that I know is a request and a response somewhere, and I’m the slow middle layer between them.

So I signed up for an API course.

Not because I can’t read documentation. I can. I’ve wired up enough endpoints to get a thing working, and then walked away without really understanding what I built. That’s the problem. I’ve been pattern-matching off Stack Overflow answers and half-remembered examples, and when something breaks I don’t debug it, I just try a different snippet until the error goes away. That’s not knowledge. That’s superstition with a terminal open.

What I actually want is the shape of the thing. Why REST is arranged the way it is. What a proper auth flow looks like when it isn’t just an API key pasted into a header. Rate limits, pagination, idempotency, retries, webhooks that fire twice. The unglamorous parts that separate a script that works on your laptop from something you’d let run unattended.

The concrete goal is smaller than it sounds. I want to stop copy-pasting into WordPress. I want analytics to arrive as data instead of a dashboard I screenshot. I want the domain portfolio — expiry dates, marketplace listings, nameserver groups — to live somewhere I can query, not in a spreadsheet I export every few months. None of that is hard. All of it is currently manual because I never sat down and learned the fundamentals properly.

There’s also the fact that everything worth connecting to now is an API first. Model providers, registrars, CDNs, payment processors. The interesting capability isn’t inside any one of those services, it’s in the wiring between them. If you can’t do the wiring, you’re stuck using whatever interface someone else decided you should have.

A course is a slightly embarrassing thing to admit to at this stage. I’ve been doing this a long time. But I’ve noticed that the gaps I never closed early are the ones that keep costing me, quietly, in hours per week. Better to be a beginner on purpose for a few weeks than to keep being an accidental one indefinitely.

I’ll write up what actually sticks.
