  secret: "your_facebook_secret_key"
  page-access-token: "your_facebook_page_access_token"

whatsapp:
  account_sid: "your_whatsapp_account_sid"
  auth_token: "your_whatsapp_auth_token"
  phone_number: "your_whatsapp_phone_number"

slack:
  slack_token: "your_slack_token"
  slack_channel: "your_slack_channel"

The facebook section is used to configure the credentials for the Facebook Messenger integration.

The whatsapp section is used to configure the credentials for the WhatsApp integration.
