WhatsApp is owned by Facebook (now known as Meta). In order
to use this Service and interact with your customers we must setup a WhatsApp
business account on your behalf. Meta (Facebook) require the Meta Business Manager
ID in order to setup the WhatsApp business account. Without this number we will
not be able to complete setup.
Note: If you have an older Facebook page it may be possible you do not yet have a Meta Business Account. A Meta Business Account allows you to manage Facebook, Instagram and Whatsapp under one login. The link above may take you to the landing page for signing up to a Meta Business Account. This only takes a minute and the information required is your name, your business name and your email address. After you click sign up and fill this in you will be able to access the Business Manager ID page here: Facebook Business Settings
