Why Ominiflow?

Most WhatsApp Cloud API setups require:

1. Meta Developer App
2. Business Manager
3. System user + permanent token
4. Webhook verification
5. Test number configuration

With Ominiflow Embedded Signup:

Connect Facebook → Get testing number → Start calling the API

You only use an OMINI_ API key. Meta access tokens stay on Ominiflow servers.

---

Install

npm install @ominiflow/whatsapp

Alpha: you can also copy src/ into your project until the package is published to npm.
