Every week in my Tuesday Lunch & Learn livestream, we choose a useful software development skill, define a challenge related to that skill, and solve the challenge live. This week, we’re looking at how to program idiot-proof APIs.

When somebody uses your API, will they understand how it works? Will they be guided away from obvious mistakes?
