What Is An API? The Clearest Explanation (With Real Examples) | Systems with Sana

Every app on your phone is secretly talking to other apps right now. The bridge that makes that happen is called an API — and it might be the single most important concept in all of modern software.

When you book an Uber, Uber calls Google Maps' API for directions, Stripe's API to process your payment, and Twilio's API to send you an SMS. Uber built none of those things. They just called APIs that already existed.

In this video I explain what an API is, how it works, and why it's the reason modern apps can be built in weeks instead of years.
