First of all, an “API” is much bigger than a “web API”. But, these days when someone says it they mean the web version (as much as that chaps my ass). Anyway, you have to learn them. Whether you are a ops person (consuming, debugging, and hacking them) or a dev (creating them).
Good API design is something that takes years of experience. It’s about
organization, business and systems and domain analysis, and all that
stuff that goes into good database design as well. But, you can’t make
one without first learning to make a web server. These days the dominant
language for API creation is Go using nothing more than net/http. This
is because Go has the strongest standard library of any enterprise
computing language, compiles to a single FROM SCRATCH (Dockerfile term)
binary, and is highly concurrent and portable.
Here’s a resource for getting started. I’ve not looked at it much, but Twitch streamer het_tanis recommends.
