# Learn WhatsApp

> The ideas behind building on WhatsApp — why the channel works, which product to use, the message types available, and how to think in flows. Knowledge that stays true even as tools change.

**Learn** is about WhatsApp the platform, not any one tool for building on it. The channel has its own grain — a set of message types, a few hard rules from Meta, and a way of thinking about conversations that rewards some designs and punishes others. Understand that grain and everything you build on top of it goes more smoothly.

These pages answer the questions that come *before* you open a builder:

* **Why build on WhatsApp at all**, and what becomes possible when your product lives where your customers already are.
* **Which WhatsApp product** to use — and why starting on the wrong one is the costliest mistake.
* **What message types exist** on the platform, and what each one is for.
* **How to think in flows** — designing a conversation that people actually finish.

<Note>
  This is knowledge that stays true even as the tools around it change. A button is still a button, the 24-hour window is still the 24-hour window, and a good conversation is still a good conversation — whatever dashboard you happen to be looking at.

## Learn vs. Tips & Tricks

It's worth knowing where to look for what.

* **Learn** (these pages) is platform knowledge — the concepts that hold across any WhatsApp project, regardless of how it was built.
* **[Tips & Tricks](/guides/testing)** is Paige knowledge — the practical craft of operating *your* bot: testing before you go live, reading logs, version history, using the mobile app, and prompting the AI well.
