WhatSaaS Meta Cloud — Official WhatsApp Cloud API with One-Click Embedded Signup (Add-on)

This is NOT a standalone product. WhatSaaS Meta Cloud requires the WhatSaaS Web Platform (v1.0.5+) to be installed and running. This plugin adds official WhatsApp Cloud API onboarding via Meta’s Embedded Signup. Please ensure you have the web platform set up before purchasing this add-on.Description
WhatSaaS Meta Cloud is a plug-and-play add-on for the WhatSaaS platform. It lets your customers connect their official WhatsApp Business numbers in one click using Meta’s Embedded Signup — no manual token copying, no Business Manager headaches. Messages flow through the official WhatsApp Cloud API.
How It Works
Admin configures the Meta App credentials in Admin > Channels (App ID, App Secret, Configuration ID, Webhook Token)
User opens Settings > Connect and selects the Meta Cloud tab
User clicks Connect with Meta — the Embedded Signup popup opens
User logs in with Facebook and selects their WhatsApp Business number
The plugin exchanges the authorization code, registers the number, and creates the instance
The number is instantly ready to send and receive messages
Requirements
WhatSaaS Web Platform: v1.0.5 or later — the Meta Cloud plugin is an add-on.
Meta Developer Account: A Meta for Developers account and a Business Portfolio.
Meta App: With the WhatsApp and Facebook Login for Business products, plus an Embedded Signup configuration.
