Having worked for a number of SaaS companies, I’m always surprised by the number of non-developers who use APIs.

These are founders, managers, marketers, and customer support people who need to solve a problem. It might be as something as simple as “update this spreadsheet when a new order comes in.”

Smart API developers write their API docs for both technical and non-technical audiences. They’ll also point non-technical audiences to abstractions (like Zapier) that make using APIs easier.
