Imagine you are sitting by your phone, eagerly waiting for a friend to send you a message with some important news. Now, think about doing the same thing but with two computers. This is, in the simplest sense, what a webhook does. It's a way for one computer to let another computer know that something has happened without the other one constantly checking for updates. Welcome to the digital equivalent of a friendly nudge.

Shrinkflation is a clever blend of the words "shrink" and "inflation," capturing the essence of the process. It's a stealthy form of inflation that affects consumers directly, though it may not always be immediately noticeable. Instead of increasing prices, companies reduce the size or quantity of their products, effectively raising the price per unit without alarming consumers with sticker shock. This tactic is often used by food and consumer goods companies to handle rising production and material costs without losing customers.
