WhatsApp Connected System

Hi  [mention:d9737c9b566a47159485a573139116ad:e9ed411860ed4f2ba0265705b8793d05] ,

While using the base url from the documentation of Meta, it is difficult to implement Webhooks in Appian, since Whatapp business API works well with Webhooks whereas Whatsapp Business Connected System Plugin has already resolved this issue.

[emoticon:599cc6d89e2145289084ee73d7cb364b] WhatsApp Business Connected System (plug-in):

• 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.

[emoticon:3f2c51800d4e449b9bd994fe2466ddaa] Custom Connected System with https://graph.facebook.com/:

• 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

• 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
