Hi, does anyone know what's the difference between using WhatsApp Business Connected System (plug-in) and Connected System with the base URL https://graph.facebook.com/

This is Appian’s pre-built connected system template for WhatsApp Business.
It abstracts away a lot of the complexity — like authentication setup, request formatting, and API endpoint wiring.
You just configure your credentials and fill in a few fields — no need to manually build REST calls.
Ideal for quick implementation and low-code convenience.

This is a manual REST integration where you define every aspect yourself.
You need to handle:
Auth token management
Custom headers and request payloads
Endpoint paths like /v18.0/{{phone_number_id}}/messages
/v18.0/{{phone_number_id}}/messages
Useful when you need full control or advanced custom behavior that the plug-in doesn’t expose.
So in short:
Use the plug-in for ease and speed.
Use the custom REST setup if you want flexibility
